In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

In this activity, learners of all ages will experiment with paint and printmaking.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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

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

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.

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 activity, learners will explore how and why weight distribution works.

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

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.
