In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

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

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity about tangrams, learners print and cut out their own tangram shapes and solve puzzles by fitting these geometric pieces together in a variety of ways.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

In this activity, learners will be able to measure themselves in nanometers. A nanometer is a billionth of a meter, a unit of measurement used in nanotechnology.

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

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

In this activity, learners take their own pulse and explore how heart rate is affected by various activities.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.
