This lesson focuses on how materials behave differently as their surface area increases.

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this electrochemistry activity, learners will explore two examples of electroplating.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners conduct tests for proteins, glucose, and starch.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this activity, learners stain fabrics--on purpose!

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.
