In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

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.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

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 meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners compare the number of letters in the names of the people in their families or group of friends.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

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 Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

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

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

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

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this math activity, learners explore probability as they play a game. Learners will categorize everyday events as either impossible, possible or certain.
