Shape Stamping
Source Institutions
In this activity, learners will explore two-dimensional shapes that are found in three-dimensional shapes. Learners will explore geometry, design, color and tool use through this activity.

Lava Lamp
Source Institutions
In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.

Be a Plumber
Source Institutions
In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

Hidden Color Chemistry
Source Institutions
In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

Squishy Letters
Source Institutions
In this activity, learners will practice writing while making a fun messy craft. Learners will explore texture and color as well as develop writing and fine motor skills through this activity.

Chromatography
Source Institutions
In this activity (page 3 of the PDF), learners will observe a physical change.
One-Cut Paper Stars
Source Institutions
Here's a very simple activity if you have paper and scissors: make one cut, unfold, and you have a beautiful star! A great way to learn about polygons and origami mathematics.

Our Beautiful World
Source Institutions
In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses.

Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

Make a Totem Pole
Source Institutions
In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Pop Bottle Whirligig
Source Institutions
Learn about friction and kinetic energy with this cool spinning toy.

Size It Up
Source Institutions
In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.

Fraction Penguin
Source Institutions
In this craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

Shaving Cream Marbling
