This activity offers learners and their families several ways to raise their awareness together about home water.

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

See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

This is an activity about music, movement, and math. Learners will start a rhythm pattern with 2, 3, or 4 beats. For instance, tap your foot, jump, clap, repeat.

This simple but open-ended math game introduces basic probability concepts using coins and dice. Players roll the dice and collect coins to match the number rolled.

In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

In this quick activity/demonstration (5th on the page), learners explore depth perception.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this activity, learners investigate static electricity using everyday objects at four different stations.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
