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

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.

In this activity, caregivers and young learners work together to make a scale from household materials to compare different weights--an essential principle in early math.

These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

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

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

In this activity, learners play a game similar to Tic-Tac-Toe. In this version, learners try NOT to get three-in-a-row. The player who gets three-in-a-row first loses!

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.
