Students will learn about the the hazards chemicals pose to the people who use them while learning about states of matter and kinetic molecular theory. First, students examine physical properties and hazards of substances and mixtures. Next, students examine how different gases respond to temperature changes and how different concentrations of salt water respond to temperature changes. Students engage in collaboration, analysis of data through board discussions, and writing an analysis using claim-evidence-reasoning. Using a phet simulation, students then model what happens to particles during increase and decrease in energy. Students then investigate thermal transfer through a water mixing lab. Finally, students engage in an ice cream engineering activity to examine how different substances in similar conditions can have different properties which may be harmful or beneficial.
In Part 1 of this unit, students will learn about data collection, graphing skills (both by hand and computer aided [Desmos]), and the fundamental mathematical patterns of the course: horizontal line, proportional, linear, quadratic, and inverse. Students perform several experiments, each targeting a different pattern and build the mathematical models of physical phenomena. During each experiment, students start with an uninformed wild guess, then through inquiry and making sense through group consensus, can make an accurate data informed prediction.
Students will learn about elements, atoms, and the Periodic table through the phenomena - How do you know if your water is safe to drink? What kind of substances in water might be hazardous? First, student will learn atoms are made up of subatomic particles, which give rise to predictable properties through a phet simulation. Next, students will try to build their own table looking for patterns in element cards. Students will then look at properties of elements which are divided into metals and nonmetals. Student will then look at electron configuration through a POGIl activity. Students will also complete a flame test activity. Finally, students when end the unit with a engineering project examining water quality to determine if it is safe to drink.
Students are confronted with a scenario of a student who is texting and driving in the school parking lot and they are tasked to determine the effect of various parameters to see if a student will collide with a pedestrian. Students must begin by breaking the scenario down into more manageable parts to determine what must be studied about the situation. Through a series of labs and activities, students learn how to model and predict situations with constant velocity and acceleration. Then, coding a spreadsheet, students model the complex situation of a texting driver, reacting, and braking during a potentially hazardous situation to create an evidence-based argument.
In order to contextualize the Energy unit, students are tasked to engineer a bungee cord that will optimize the enjoyment of a doll’s bungee jump. To do this, students first develop the mathematical patterns through inquiry on gravitational energy, kinetic energy, and elastic energy. Once the patterns have been established, students further build on their spreadsheet coding skills, in order to use computational thinking to create a program that will help predict the length of bungee cord necessary for a variety of situations.
In the Nuclear Change unit, students will learn about nuclear change through examining the phenomena of radon. Three questions that students will answer at the end of the unit are: is air we breathe in buildings radioactive and what is Radon and how does it affect health? First, student will investigate what is radon. Next, students will build a atom to learn how atoms can exist in stable and unstable isotopes. Students learn about types of radiation and then complete an inquiry about half-life of atoms. Half lifes can be used to map geology and assess danger timelines. Next, students learn how nuclear change occurs through fusion or fission. Additionally, students learn that the high energy released has military/commercial uses, and the legacy of cosmic, geologic and human events and activities has impacted where radioactivity exists on the earth. Students end the unit with a cumulative Socratic seminar about Hanford while assessing risk and benefits of using nuclear reactions and recovering sites contaminated by radioactive materials is complex. At the end of the unit students discuss the following question: should parts of the Hanford Nuclear Reservation be opened as a recreation area or returned to Native Americans?
This unit is centered on designing a shoe for a customer. Students decide on a particular type of shoe that they want to design and utilize ideas of force, impulse, and friction to meet the needs of a particular customer. Force plates are used study the relationship between force, time, and impulse to allow students to get the mathematical models that allow them to make data informed decisions about their shoe design.
The phenomenon that launches this unit is a cell phone call to a student in the class, where the caller on speaker phone asks “How are you hearing me?”. Over the course of the unit, students discover the patterns with waves. Then use that understanding to explain ultrasound medical imagining technology and ultimately how cell phones work. Cell phone communication is operationalized by the engineering challenge of communicating a three letter signal by first coding a spreadsheet to digitize the signal in binary (ASCII), then transmit the digital signal using light and sound (AM and FM), then receive and decode the signal to complete the communication. This project models the sending and receiving of a text message.
This unit is loaded with phenomena. The real world task of being a member of Oregon's Energy Commission that must create a 50-Year Energy Plan propels students through a learning arc that includes electricity, magnetism, power production, and climate science. After the Request for a 50-Year Energy Plan students jigsaw energy sources and power production. They need to understand the basic physics of how generators works leads us to build and explore motors (starting with speakers which also connect to the Waves & Technology unit) and inefficient generators (electric guitars). The need for large amounts of energy and efficient generators motivates us to engineer wind turbines and optimize solar cells for a local facilities use. Creating the rubric to evaluate large scale power production launches us into climate science. With all the learning of the unit students and many real world constraints student finally complete, compare, and evaluate their 50-Year Energy Plan.
By using the hook of Halley’s comet, dark matter, and dark energy students data mine Newton’s Law of Universal Gravity and build an and evaluate other arguments for the Big Bang.
This lab-based course covers the foundational principles of modern life science as outlined in the Next Generation Science Standards (NGSS). It also includes approximately a third of the Earth and Space Science standards, primarily those connected to environmental science and ecology. The course emphasizes all three dimensions of the NGSS, with special attention to the crosscutting concepts of Patterns and Energy and Matter. Additionally, scientific inquiry and engineering design practices are emphasized throughout the course. The course is designed to follow a chemistry course and so builds on student understandings of molecules as they explore the biomolecular underpinnings of life's functions, the evolution of life, and the interactions of life in ecosystems. Technological, historical, political, and environmental aspects of biology will also be addressed. Critical thinking, data analysis, and argumentation from evidence are also emphasized.
Anchoring Phenomenon: A baby is born and seems perfectly healthy, but after a few days starts to exhibit strange symptoms that could lead to physical impairment or even death. What is causing the problem? Can the baby be saved? Unit Essential Question: How and why do cells make the molecules they need and get rid of the molecules they don’t need? What happens if steps in this process aren’t working?
For this unit plan, see the old unit calendar (link on left sidebar, click ALT3 tab at the bottom). Once we update this unit to the new Doc template, we will post it here. This is now unit 3, but it used to be unit 2 (we will update file and folder numbering as we continue to revise the units). Thanks for your patience as we work hard this year to update all of the materials to the new unit template and unit/standards arrangements.
