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

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

Put on a pair of gloves and be the conductor of your invisible orchestra!

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this activity, learners can observe chaotic motion. A magnet tied to a piece of string makes a pendulum, which swings over three sets of fixed magnets.

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.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

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.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

In this activity, learners discover why only some types of plastic can be recycled.

In this online activity, learners discover how random variation influences biological evolution.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.
