In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this activity, learners will investigate the part of soil. Explore how clay, silt, and sand make up the dirt in your background. Activity includes step-by-step instructions and extension ideas.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this design challenge activity, learners invent a convenient way for someone using crutches or a wheelchair to carry small personal items.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

In this activity on page 5 of the PDF, learners use their knowledge of energy and batteries to create homemade flashlights.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
