In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

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

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

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

In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.

In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

In this activity (8th activity on the page) about the sense of touch, learners make their own set of Braille letters. Learners use glue to make raised dots on a Braille Alphabet Sheet.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!

In this activity, learners explore the great pump in their chests--the human heart!

In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.
