Source Institutions
In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

Build a Bubble Circuit
Source Institutions
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

Glow in the Dark Jello
Source Institutions
In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

Whirling Windmills
Source Institutions
In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

Soap-Film Painting
Source Institutions
Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

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.

Planaria Fishing
Source Institutions
In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

Momentum Machine: Speed up your spin
Source Institutions
Spin in an office chair holding milk jugs! Plus, learn physics. Very fun (but stay safe) activity from the Exploratorium Science Snacks series.

Center of Gravity
Source Institutions
A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.

Jelly Beads
Source Institutions
Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

The Crayon Rock Cycle
Source Institutions
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

Holding Charge
Source Institutions
In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

Dusted!
Source Institutions
Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.

Dinosaur Bone Experiments
Source Institutions
This activity features two connected hands-on activities about dinosaur bones.

Root Observations
Source Institutions
In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

Balloon Bugs
Source Institutions
In this activity, learners make balloon models of disease-causing bacteria.
