In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

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

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

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

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

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

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
