In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

En esta actividad, los aprendices aprenderán que es la cromatografía y cómo usarla para separar diferentes sustancias - en este caso,usarán los colores.

This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity, learners will explore acid-base reactions and create their own bubbly results.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

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

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

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.

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.
