In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

How many colors make black? Gather as many water soluble black markers as you can find.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.

In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

In this archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

En esta actividad la tira cómica muestra a los participantes como pueden hacer un experimento simple para ver cuales líquidos son ácidos.

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