Understanding of the Structure of an Amino Group
Students review the characteristics of acids and bases. They examine the structure of an amino group and compare amines to ammonia. They work together to develop the concent of polymerization.
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
What Is Chemistry, Anyway?
Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.
Curated OER
Learning Lesson: Crunch Time
Students demonstrate the effect of heat on pressure. They use a 2-liter bottle and hot tap water to complete the experiments. They also discuss thunderstorm safety rules.
Curated OER
Demonstrating That Light is Dissipated as Chlorophyll a Fluoresces
Students examine the concepts of light and chlorophyll. They participate in an experiment in which the chlorophyll shows as a red ring on the test tube. They answer discussion questions to end the lesson.
Curated OER
Coefficient of Kinetic Friction and Surface Area
Students investigate coefficient of friction with respect to surface area and applied force in contact with the sliding force.
Curated OER
Causal Patterns in Density Phenomena
Learners consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
Curated OER
Atoms, Kinetic Theory, Solids and Fluids
Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

Urban Impact on Chollas Creek (California): A Field Study
Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.
Curated OER
Autumn
Students examine the cycle of nutrients in a forest. They research the concepts of decomposing and recycling within a forest.
