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

In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

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

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 add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this chemistry demonstration, acid rain is simulated in a petri dish.

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.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this activity, learners explore the flexibility of polymer chains by pushing sharpened pencils through a Ziploc bag.

In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

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

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this activity, learners perform a simulated blood test procedure.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.
