Seventh graders study elapsed time, radioactive decay and half-life.  In this time machine lesson students complete several activities and view a presentation. 

To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.

High schoolers create a biosphere using the computer program SImEarth. They work in small groups to create "Daisyworld" in which they model aspects of the Gaia hypothesis. They form a question to answer and choose variables to...

Students model the biosphere and manipulate variables affecting change and plan their experiments with the help of others. They describe their question, hypothesis, and methods of investigation.

Students describe and define xenophyophores.  In this protozoa lesson students divide into groups and complete a lab activity.
