Curated OER
Corrosion & Rust
Students examine how and when rust and corrosion occur. In this corrosion lesson students complete an experiment to see why metals rust.
Curated OER
Warm and Cold Air
Students examine what happens to air when it is heated or cooled. They conduct an experiment using bottles and balloons, record and discuss their observations, and write a hypothesis.
Curated OER
Acid Rain
Students create acid rain using carbonic, nitrous, nitric, and sulfurous acids.
Curated OER
Hess's Law
For this reactions worksheet, students use Hess's Law to calculate the heat gained or lost by different reactions. Students determine if the reaction would occur spontaneously at a given temperature. This worksheet has 9 problems to solve.
Curated OER
Enzymes
Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.
Curated OER
CO Buildup City
Students conduct a controlled experiment. They collect data in an organized manner. Students analyze data to reach a conclusion and communicate findings. They explain how city size, temperature, and pollution is related to the air quality.
Curated OER
Yo-Yos, Tow-Yos and pH, Oh My!
Students explore how hydrothermal vents are formed and where they are located on the ocean floor. They study how scientists use CTDs to locate hydrothermal vents.
