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

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 activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this math lesson, learners explore and investigate measurement using standard and non-standard units.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this challenge, learners figure out how to make a juice stain disappear.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

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

In this activity, learners will use their nose to sniff out hidden scents using extracts and cotton balls. Activity includes materials list, game instructions, STEM connections and more.
