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 explore how nanosized structures can create brilliant color.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

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.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

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

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

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

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

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

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

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