Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.

In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this activity, learners create their own bird species using arts and crafts materials. The bird call recordings are not online so the introduction activity can't be done, but everything else can.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

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

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.
