About 70% of our planet is covered by oceans and seas: large, full of life and mysterious.
They are a source of food, way of transportation, oxygen producer, and more.

But the sea is in danger: overfishing, plastic waste, acidification, species extinction.
We need to better understand the marine life and deal with it in a sustainable way, because our life is closely linked to the sea. If it is sick, we cannot stay healthy.

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).

In this 1-2 week engineering design lesson, students will design and build water filters out of natural materials to simulate a filter system (bioswales) that cleans storm-water runoff before it soaks into the ground or enters a city’s storm-drain system. Their ultimate goal is to determine the combination and sequence of materials that best clean polluted water. Using materials easily found in pet stores and garden centers, students use the scientific method, students design to test and retest their designs and record, display and analyze their results.

The study of biomimicry and sustainable design promises great benefits in design applications, offering cost-effective, resourceful, non-polluting avenues for new enterprise. An important final caveat for students to understand is that once copied, species are not expendable. Biomimicry is intended to help people by identifying natural functions from which to pattern human-driven services. Biomimicry was never intended to replace species. Ecosystems remain in critical need of ongoing protection and biodiversity must be preserved for the overall health of the planet. This activity addresses the negative ramifications of species decline. For example, pollinators such as bees are a vital work force in agriculture. They perform an irreplaceable task in ensuring the harvest of most fruit and vegetable crops. In the face of the unexplained colony collapse disorder, we are only now beginning to understand how invaluable these insects are in keeping food costs down and even making the existence of these foods possible for humans.

Begin Research“Where Do I Start?”Do you have an assignment to write a research paper but you’re not sure where to start? Take a deep breath and begin by carefully reading the assignment requirements. This will help you understand the work you need to do.First, let’s think about what we mean when we say “research.”HOW MUCH DO YOU ALREADY KNOW?What makes a good topic?It is broad enough that you can find enough information on the subject.It is focused enough that you are not overwhelmed with too much information.The topic is interesting to you.All of the above.If you don’t know much about your topic, what resources would be most helpful when you being your research?Encyclopedias and websitesScholarly articlesNewspapers and magazinesStatistical informationIt is always a good idea to brainstorm different words for similar ideas when you first begin to research your topic.TrueFalseWhat statement below is generally true about beginning research?It is pretty easy to find information on any topic.As long as you have a good topic, researching for it will not take a long time.No matter t he assignment, good research takes time and effort.None of the above.ANSWERSAll of the above.2.1True4.3Read Your Assignment CarefullyBefore you can even begin your research, though, you need to read the assignment instructions carefully—more than once! This will help you understand the work you need to do.Highlight topic guidelines, required length, and the types of information sources allowed.Let’s take a look at a sample assignment.UNDERSTAND YOUR ASSIGNMENTLily is taking a University Studies class and must complete this assignment:In this paper, you will analyze the scientific aspects of a known environmental problem and identify and discuss at least two proposed solutions.Now, analyze this assignment step by step.Find the words that tell you what to do (think verbs!): analyze, identify, and discuss.Find the limits of the assignment: scientific aspects and two proposed solutions.Find the key theme: a known environmental problemBy reading the assignment carefully, we know that Lily has to analyze an environmental problem and identify and discuss at least two proposed solutions.Pick a Good TopicLily’s assignment is broad enough to give her some choices when picking a topic. So, what makes a good topic?It interests you! You’ll enjoy it and do a better job.It meets the requirements of your assignment.It’s broad enough to give you several search options.It’s focused enough that you’re not overwhelmed with information.HOT TIP!Explore the library’s databases to get you started.Browse newspapers and news sources.Talk to your instructors and fellow students.Consult with a librarian.TOO BROAD, TOO NARROW, OR JUST RIGHT?Air pollution in urban areasToo broadToo narrowJust rightRespiratory diseases in children in high-density urban areasToo broadToo narrowJust rightEnvironmental consequences of California’s October 2007 forest firesToo broadToo narrowJust rightPolar bear adaptation to global warming in the ArcticToo broadToo narrowJust rightRenewable energy in the United StatesToo broadToo narrowJust rightThe design and implementation of Cal-Cars—the California Cars InitiativeToo broadToo narrowJust rightANSWERSToo broad. You’d need to identify an aspect of air pollution to narrow down the scopeJust right! This is a good topic. You’ll continue to refine your ideas as you learn more about the topic.A bit narrow. It will be hard to find information on just one event. Look more broadly for information on forest fires in California or the West.Just right. There should be just enough information to get you started. You will continue to refine your ideas as you learn more about the topic.Too broad. This is a good starting place, but you’d want to focus the topic by selecting a specific renewable energy like solar power or wind.Too narrow. It’s going to be difficult to find information on such a narrow topic. Broaden the focus to look at initiatives like this one that are less regional.Identify Potential IdeasNow it’s time to really focus your topic. Browse a few resources for ideas and identify different aspects of the topic.Remember, if you pick a subject that interests you, you’ll enjoy the research process much more!Customize Your TopicLet’s say your assignment is to research an environmental issue. This is a broad starting point, which is a normal first step.One way to customize your topic is to consider how different disciplines approach the same topic in different ways. For example, here’s how your broad topic of “environmental issues” might be approached from different perspectives.Social Sciences: Economics of Using Wind to Produce Energy in the United StatesSciences: Impact of Climate Change on the Habitat of Desert Animals in ArizonaArts and Humanities: Analysis of the Rhetoric of Environmental Protest LiteratureTurn Your Topic into a QuestionWhen you’ve chosen a topic, it’s time to ask some questions. Using “environmental issues” as our general research interest, let’s ask some questions about environmental issues and agriculture.How: How do government agricultural subsidies impact the price of food?  How does the use of pesticides affect food safety?Who: Consumers, farmers, farm workersWhat: Food safety, pesticides, food prices, genetically modified food, organic farmingWhere: United States, developing nations, European UnionWhy: Why does the European Union ban the sale and distribution of genetically modified food?What’s Your Angle?Let’s say that the most interesting question that emerged from the last exercise was: “How does repeated pesticide use in agriculture impact soil and groundwater pollution?”Find Your KeywordsNow that we have our sample research question, we need to identify the key concepts and their related keywords.Using our research question, “How does repeated pesticide use in agriculture impact soil and groundwater pollution?” we might consider these keywords:A SYMPHONY OF SYNONYMSLet’s examine our research question again:How does repeated pesticide use in agriculture impact soil and groundwater pollution?Now analyze this assignment step by step:Find important words and phrases that describe this topic (you can ignore common words that don’t have a lot of meaning, such as prepositions, articles, and adjectives): pesticide, agriculture, soil, and pollution.Now, think of some synonyms for the keywords you found:pesticideagrochemicals, pest management, weed management,diazinan, malathionagriculturefarming, food crops, specific types of cropssoilclay, organic componentsgroundwater watershed, water resources, water table, aquaticspollutionenvironmental impact, degradation, exposure, acid rainWhy are synonyms necessary? You’ll often need to search for different words relating to the same concept.Dive Into a Sea of Resources!Browse through general sources to get familiar with your topic. You will find many sources for locating background information. Remember our point from earlier in this tutorial: the source you select will determine what you find. Make sure you spend your time looking in the right places.HOT TIP!Is there enough info on your topic? If not, review the earlier steps for starting your research. It’s normal to refine and revise your topic multiple times.What Do You Know?Once you’ve established your focused topic, you need to get familiar with it by doing some reading. Start with more general sources and then work up to more specific and detailed sources. Where you go next depends on how much you know.So, just how much do you know about your topic?Not All That MuchI’ve Got the BasicsI’m Ready for DetailsSounds like you need the type of information typically found in encyclopedias and websites.Sounds like you’ve got a basic understanding of your topic and just need to learn more. Check out books, magazines, and newspapers.Specific information is what you need. You’ll want to find relevant scholarly articles, statistical sources, and government publications.Matching Resources to Your Information NeedNewspaper: Current regional or local informationScholarly journal article: Detailed analysis of a complex problem.Book or book chapter: Summary of what is known about a topic.Encyclopedia or website: Factual information like names, dates, and definitions.TEST YOURSELF: WHAT HAVE YOU LEARNED?What are the characteristics of a good topic?(Select all that apply) It interests you.It meets the requirements of your assignment.It’s broad enough to give you several search options.It’s focused enough that you’re not overwhelmed with information.Rank the following questions in order from most general to most specific (1 being the most general):Are pesticides bad?Do video games cause violent behavior in adolescent males?Are agricultural workers in Mexico at a higher risk of health problems due to pesticide exposure because of lax government safety standards?Is there a relationship between fast food consumption and obesity?What is the best way to focus  your topic?Think about the discipline that you are researching for.Tailor your topic to the requirements of your assignment.Talk to a librarian about the resources that are available for your topic.All of the above.Pick the best set of keywords to begin searching for information on global warming.Rising ocean levels, air pollution, greenhouse gasesBiodiversity, atmospheric temperature, ozone layerGlobal climate change, greenhouse effect, atmospheric carbon dioxideEnvironment sustainability, alternative energy, biofuelsWhy is it a good idea to use different words to describe similar ideas when you are beginning research?(Select all that apply) Because there is only one right answer and you can find it by trial and error.Because  using different words will help you cast a broader net than just using the same term over and over.Different researchers might use different terms to describe the same idea.You might spell some of the words wrong and not get any results.What is the most difficult aspect of beginning to research a topic that you don’t know very much about?You don’t know enough about the topic to know what is important and what is not.You don’t understand the technical aspects of the topic.It takes a lot of time to do research.All of the above.For you, what the most difficult part about beginning your research?ANSWERSA good topic will incorporate all these characteristics.1 = Are pesticides bad?2 = Is there a relationship between fast food consumption and obesity?3 = Do video games cause violent behavior in adolescent males?4 = Are agricultural workers in Mexico at a higher risk of health problems due to pesticide exposure because of lax government safety standards?The more a research question incorporates the concepts of Who, What, When, Where, Why, and  How the more specific it will be.All of the above.4.3; think carefully about which terms are closely related to global warming.5.2 and 5.3; there may be many ways to describe a single topic. Using as many related words as possible will help you find the most information!All of the above; remember that research takes time and energy and isn’t an easy thing to do!No matter what, coming to the library and talking to a librarian will help you get started. Finding information effectively and efficientlyLevel 2 teaches you how to structure a search for the information you need to write a paper, for example. You will learn the following:how to construct a search strategy using the aspects defined in level 1how to perform a smart search using the information sources available at TU Delft LibraryDetermining search termsNow it is time to do an actual search! In level 1 you divided the search topic into its different aspects. What’s next? Are you going to use Google and type in all the aspects, like you probably do every day? What will you do with all the search results? Are you going to study them all? No, there is a smarter way!Exercise 1Plug in your earphones or turn down the volume and watch the clip ‘Web Search Strategies Explained in Plain English‘ by Commoncraft about smart searching on the web.Searching the web is very similar to searching other information sources such as Worldcat Discovery. Doing the following exercise will teach you how to apply the aspects of your search topic in a smart search. Complete the exercise on how to find suitable search terms matching the aspects of the search topic. Determining search strategyNow you are going to convert the synonyms you have found into a smart search strategy. You have to use search operators to use all the synonyms properly.Exercise 2Study the TUlib module Search operators.If you want to perform a smart search, you must combine your search terms. Complete thisexercise on combining search terms with Boolean operators.Towards information sourcesNow you have formulated a search strategy, which you will use to search the various information sources. But where to start? How do you choose which information source you want to use? This table gives an overview of the differences between Worldcat Discovery, Scopus and Google Scholar and helps you determine when to use each one.Exercise 3Watch the first two sections (“Basic searching” and “Retrieving documents”) of this video about searching in WorldCat Discovery (which includes the TU Delft Library catalogue).Watch this video with an example of a search strategy carried out in article database Scopus.Complete the exercise on carrying out your search strategy in various information sources.Now you have learned how to convert the aspects of your search topic into a search strategy and how to apply this strategy in a number of information sources.You can find other relevant information sources for your subject area in the “Useful links” overview in the section “What’s next”.

Climate change is an urgent problem. Because it is causing new weather extremes and fatal catastrophes, climate change is better termed climate disruption. Bending the curve to flatten the upward trajectory of pollution emissions responsible for climate disruption is essential in order to protect billions of people from this global threat. Education is a key part of the solution.

Biochemical Oxygen Demand" is an essential educational resource tailored for environmental science and engineering students, aiming to deepen their understanding of water quality assessment and pollution control. This unit comprises a series of engaging lessons, each meticulously designed to explore the dynamics of Biological Oxygen Demand (BOD) and its implications for aquatic ecosystems.Beginning with foundational concepts of dissolved oxygen and BOD, learners progress to advanced topics such as the Dissolved Oxygen Model and SAG (Submerged Aquatic Growth) curve analysis. Through interactive discussions and problem-solving exercises, students develop proficiency in calculating key parameters related to water quality, including DO concentrations and BOD levels.

In this activity, students construct "flying birds" (pollution collectors) from paper and wire hangers. Students hang up their birds to see how they react to air pollution, and compare and make observations about the differences in the birds.

In this lesson, the music and visuals of the Gorillaz album Plastic Beach is used to introduce students to the issue of plastic waste. Students are asked to calculate the percentage of plastic that goes unrecycled internationally, and illustrate a model of polyethylene to better understand why the molecular makeup of plastic creates both benefits and drawbacks. Finally, they evaluate various projects that are currently being undertaken to curb plastic waste, and develop their own similar program or project that they could employ on a local level.

In this lesson, students listen to Flint-based rapper Jon Connor's song "Fresh Water for Flint" to better understand the sense of frustration and injustice people living in the city felt during the water crisis. Students then experiment with creating their own water filtration system to better understand the scientific and engineering principles behind water treatment. Lastly, they consider the biological effects of lead poisoning and determine specific, political, economic, and scientific causes behind the Flint water crisis.

Botany generally refers to the study of plants, but other organisms are often included in the field such as photosynthetic bacteria, fungi, algae, and slime molds. Plants are multicellular organisms with complex, eukaryotic cells that contain cell walls, chloroplasts, and other cell structures that are absent in animal cells. They can be studied at many levels, ranging from the molecules that comprise them to cells and tissues to organs (flowers, leaves, roots, etc.) to organ systems (shoot system and roots systems). Each structure in the plant body is adapted to optimize its function, whether it be photosynthesis, support, nutrient absorption, transportation, or reproduction. Plant physiology explores the chemistry and physics of these functions, including how they respond to the environment, coordinate responses using hormones, gather energy and nutrients, and change throughout their life cycles. Plant ecology examines even larger scales, including plant populations and their roles in communities and ecosystems. Humans rely on plants for food, fiber, and medicines, and to provide clean air, erosion control, and other services. Unfortunately, human activities resulting in habitat loss, climate change, and pollution threaten plant biodiversity, but current and future conservation efforts slow the loss of biodiversity.

Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers help us stay healthy by designing machines and medicines that support respiratory health and function.

Breathing Easier is a 5th-grade curricular program created by EarthGen. For this unit, we offer professional development training and assistance with implementation. If you are interested in implementing this program at your school or district, please let us know! Please contact info@earthgenwa.org for more information.EarthGen and Puget Sound Clean Air Agency have partnered to develop opportunities for learning about local air quality (AQ). Using interactive maps, multimedia resources, classroom discussions, community science, and data analysis, students will explore the causes of air pollution and its relationship to environmental justice. These lessons are aligned with the Next Generation Science Standards and encourage students to engage in argumentation from evidence and propose solutions to socio-ecological issues of air quality and public health for communities in Washington.  

Welcome to the online text resource for CH105: Consumer Chemistry. The focus of this textbook is to introduce students to the fundamental applications of organic chemistry to society, technology, and the development of consumer products. The first part of the textbook focuses on the basic fundamentals of measurements in chemistry, the scientific method, and an introduction into atoms and elements. The second part of the textbook focuses on an introduction to organic chemistry and how it is applied to our daily lives. Topics include fuels and energy, polymers, fertilizers, pesticides, food and food additives, household cleaners, cosmetics and personal care items, pharmaceuticals, and air and water pollution. Organic concepts covered include an introduction to intermolecular forces and solution dynamics, VESPR and molecular geometry, organic structure and basic chemical reactions.

Course Goals and Learning Objectives. The goal of this course is to give the student a basic understanding of chemistry and physical processes in the context of food chemistry, metabolism and cooking. The course also necessarily makes connections to the future sustainability of food and water. We aim to prepare the student for the increasingly urgent and complex national dialogue on the interrelated topics of global climate change, energy, pollution, extinction and the food supply. The specific objectives of this course are to provide the student with the basic vocabulary of chemistry, and a basic understanding of the experimental process as it relates to food chemistry and cooking.

Learn about one town's conflict over the issue of spraying pesticides to combat disease-carrying insects, in this video segment from Greater Boston.

SYNOPSIS: This lesson shows that different foods have different environmental impacts. Students will calculate ratios and practice proportional thinking.

SCIENTIST NOTES: This lesson is thoroughly sourced. It is engaging and suitable for students to understand how to measure carbon footprint from food sources. The activities in the lesson would also enable them to build their quantitative skills to determine the extent of CO2 impact on the environment. The lesson has passed our science review, and it is advised for classroom use.

POSITIVES:
-This lesson is great because it shows that different foods have different environmental impacts.
-It shows the great disparity between certain types of foods. For example, creating 1 kg of beef (from a beef herd) emits 99.48 kgCO2eq. Creating 1 kg of potatoes creates only 0.46 kgCO2eq. Raising beef creates more than 200x the carbon dioxide than raising the same amount of potatoes!

ADDITIONAL PREREQUISITES:
-You will need to share the Student Slideshow with students and grant them editing rights. They will all be writing in the same slideshow.
-In general, animals and animal products use far more resources than plants.
-Kilograms are used in this lesson. Some students will be unfamiliar with this unit. You can read more about the kilogram at Britannica. An easy conversion from kilograms to pounds is 1 kg = 2.2 lbs.
-Kilograms of CO2 equivalent are also used in this lesson. This is pretty abstract for the students. You can have them imagine holding a 2.2-pound ball in their hands. This ball has mass and takes up space. This is the "pollution" generated when creating different foods.

DIFFERENTIATION:
-You can create groups of students with mixed abilities.
-If a group finishes early, you can ask these extension questions:
-"Food 1’s emissions are what % of food 2’s emissions?"
-"Can you convert your answers from kilograms to pounds?"
-The Investigate section features a completed table of calculations. You can use this before the students begin their calculations. You can also share this with certain students or groups and let other groups complete their calculations on their own. Another option is to have students use the completed table to check their thinking when they are finished. There is a walkthrough of calculations in the speaker notes of this slide.
