In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

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

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

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

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.
