1 - Kinetic Molecular Theory (KMT)
Conditions of Use:
Remix and Share
Rating

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.

1: Measurements in the Laboratory (Experiment)
Conditions of Use:
Remix and Share
Rating

Chemistry is the study of matter. Our understanding of chemical processes thus depends on our ability to acquire accurate information about matter. Often, this information is quantitative, in the form of measurements. In this lab, you will be introduced to some common measuring devices, and learn how to use them to obtain correct measurements, each with correct precision. A metric ruler will be used to measure length in centimeters (cm).

2 - Elements and the Periodic Table
Conditions of Use:
Remix and Share
Rating

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.

3 - Nuclear Change
Conditions of Use:
Remix and Share
Rating

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?

Introduces the object that contains almost all of the mass in the universe, the atomic nucleus. Antimatter, beta rays, fission and fusion, the structure of the atomic nucleus, how elements on the earth were produced, how we use the nucleus in every day life, and the effects of radiation in the environment are among the topics. The site includes nearly a dozen experiments that can be done in chemistry and physics classes, along with A Teacher's Guide to the Nuclear Science and Technology Wall Chart.

Accidental Drowning or Foul Play?
Conditions of Use:

Rating

This case was developed for use in the first semester of a sophomore organic chemistry laboratory to illustrate how a combination of techniques is usually required in the identification of chemical compounds. It involves a murder mystery with a forensic twist. Students are told that two bodies have recently been recovered from two different lakes. Due to a mix-up at the morgue, the coroner's office is unable to determine which body came from which lake. The students' task is to develop a methodology to solve this mystery as well as determine whether the deaths were the result of murder or mishap. The case could also be used in instrumental analysis courses or adapted for a non-majors course in the general education curriculum.

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

This Science NetLinks lesson is intended for a high-school, introductory chemistry class or health class. The lesson begins with an article on the history of the development of aspirin. Students will then complete a lab that compares the reaction of regular aspirin, buffered aspirin, and enteric aspirin in neutral, acidic, and basic solutions. They will then analyze the results of the experiment to gain insight into how this information was used by researchers to solve some of the problems associated with aspirin. To complete the lesson, students must understand acids and bases.
