Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

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 activity, learners explore materials through paper chromatography.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

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

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

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 mark their height on a height chart and discover how tall they are in nanometers.

In this activity, learners use a string and pair of scissors to find pi in the world all around them. Take the circumference of a round object with string and cut the string to that length.
