In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Our bodies produce snot, or mucus, that we blow from our noses. In this activity, learners will create a model of how snot works and will explore how it keeps our bodies healthy.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

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

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

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

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity, learners make self-assembled polymer spheres.
