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, learners create painting machines that can paint moving forwards and backwards.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

In this activity, learners build small animated toys that move.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

No glue is needed for learners of any age to become marshmallow architects or engineers.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
