Chemistry: Metals and Non-Metals
Students conduct an experiment to test the reactivity of metals and non-metals. In this chemistry activity students test metals with different chemicals to observe the reaction. The results are used to categorize the metals.
Curated OER
Limiting Reagent
Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...
Curated OER
CAN'T TOUCH THIS!
Students discover the best practical shielding material when dealing with radioactive substances. They draw conclusions based on availability of materials, price, and best shielding properties.
Curated OER
The Connection Between Pigment and Light Colors
Students explain the mole concept and use this concept to prepare chemical solutions of particular molarities.
Curated OER
The Right Chemistry
Learners see that chemistry is the study of matter, how matter reacts and combines to create new chemicals, the changes that take place in matter and what makes up matter. This lesson provides many good ideas across the curriculum to...
Curated OER
Metalloids
Students discuss metalloids, their use as semiconductors, and their impact on the computer industry. They work in groups to create a visual timeline showing the evolution of the computer.
Curated OER
Matter
Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.
Curated OER
Matter and Energy
Students participate in a small group read aloud of the short story, "Cerium" by Primo Levi. They answer several questions about the story and then relate the reading to a lecture on Kinetic theory. After the lecture they apply the...
Curated OER
Heat Transfer
The students construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.
Curated OER
EGG-cellent POLYMER PACKAGING DESIGN
Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...
