In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

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

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.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this activity, the learner will experiment with the physics of sound production while making a sound making toy. The activity includes a video with step by step instructions.

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

In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

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.

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.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

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.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
