In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?
