The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

This activity features two connected hands-on activities about dinosaur bones.

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

This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.

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

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
