In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

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

Learners make their own simple slide rules out of paper and learn how they work.

Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

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

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

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

This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
