A collection of lessons that have middle schoolers completing a design project where they construct, test, and modify a device that uses chemical processes to either release or absorb thermal energy. Site includes work samples,...

[Free Registration/Login may be required to access all resource tools.] In this lesson, students study the difference between reactions that absorb versus release heat as well as how to measure this change in energy.

[Free Registration/Login may be required to access all resource tools.] Explains chemical property and chemical reaction.

[Free Registration/Login may be required to access all resource tools.] Provides an introduction to chemical reactions.

In this experiment, three reactions are performed in a sealed Ziploc bag so that they can be observed. Students identify whether physical or chemical change has taken place.

Learn about the process of germination in this hands-on science experiment. Includes full list of materials, procedures, and scientific explanation of why plants can survive in a variety of environments.

This lesson will give an overview of different types of chemical reactions.

Explains what an endothermic reaction is and gives four everyday examples.

A simple lab activity that allows good data collection on heat of solution.

Demonstrate how soil absorbs radioactivity by simulating the absorption of the radioactive isotope from the Chernobyl disaster into the lichen of Scandinavia. Use a chart to figure out the half-life of the isotope.

Explore how life invades, colonizes and changes over time. Model a shallow underwater volcano to see what type of island forms, investigate seed dispersal methods and describe how wing size and shape determine which birds fly where.
