Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

Iron in Cereal: Find iron in your food!
Source Institutions
Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

As Light as Air
Source Institutions
Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

Dangling Magnet
Source Institutions
In this activity about magnetism (page 13 of the pdf), learners will experiment with magnets to explore how water and other liquids affect the strength of magnetic fields.

Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

Cabbage Patch Chemistry
Source Institutions
In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Having a Gas with Water
Source Institutions
In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

Biotech in a Bag
Source Institutions
In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

Choose Your Ooze
Source Institutions
During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

Miscibility
Source Institutions
Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

What Do You Know About Microbes?
Source Institutions
This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.
