In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
