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.

Microbes are Everywhere
Source Institutions
In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

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.

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.

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.

The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.

Currently Working
Source Institutions
Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

Defining Dissolving
Source Institutions
In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

How is Coastal Temperature Influenced by the Great Lakes and the Ocean?
Source Institutions
In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

Balloon Flinker
Source Institutions
In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.
