In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

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

In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity on page 3 of the PDF, learners discover how science and Halloween are fun companions as they make paper bleed.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).
