Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

The Scoop on Habitat
Source Institutions
Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Skin, Scales and Skulls
Source Institutions
In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

Tiny Particles, Big Trouble!
Source Institutions
In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

Exploring Materials: Liquid Crystals
Source Institutions
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

Smelly Balloons
Source Institutions
In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

Design For All: Imagining Inventions
Source Institutions
In this design challenge, learners will practice empathy and design thinking skills by creating an invention of the future.

Cookie Mining
Source Institutions
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

Setting the Scene
Source Institutions
In this activity (on page 2), pairs of learners create an imaginary crime scene. One person leaves the room while the other person moves a few things around.

Design a Microexpression Zoetrope
Source Institutions
In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

Morphing Butterfly
Source Institutions
In this activity, learners explore how nanosized structures can create brilliant color.

Robot Hands
Source Institutions
This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

Gravity Fail
Source Institutions
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.

Gummy Shapes
Source Institutions
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.

Waterproof Hanky
Source Institutions
In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

Ice Melt
Source Institutions
In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

Nebula in a Jar
Source Institutions
In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.
