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

Wiggly Water
Source Institutions
This is a simple and fun activity for learners to explore water and colors.

Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.

Liquid Lava Layers
Source Institutions
In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

Crystals: Grow Your Own Garden
Source Institutions
In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

Crystal Packin' Mama
Source Institutions
In this activity, learners investigate the basic crystal structures that metal atoms form.

Density Rainbows
Source Institutions
In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

Atomic Mobile
Source Institutions
Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Special Effects Using Household Chemicals
Source Institutions
In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

Fused Plastic Wallet
Source Institutions
In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

Cooking with Chemistry
Source Institutions
In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.

Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Fill it to Capacity
Source Institutions
In this math lesson, learners rotate through six estimating and measuring centers. First, learners read the book, "Room for Ripley" by Stuart J.

Avi's Sensational Salt Dough
Source Institutions
In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

Make a Garbage Bag Kite
Source Institutions
Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

Glitter Slime
Source Institutions
In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

Glitter Globe
Source Institutions
This activity shows learners (with adult supervision) how to make a Glitter Globe, a fabulous toy that shimmers when you shake it.
