How can Clouds Help Keep the Air Warmer?
Source Institutions
In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

Super Gelatin
Source Institutions
Can gelatin (like Jell-O ®) change the speed of light?

Planting with Precision
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

Pi Graph
Source Institutions
In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

Collaboration via Slime Mold
Source Institutions
In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.

Throwing Pi
Source Institutions
In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

LEGO® Chemical Reactions
Source Institutions
This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

Antigen-Antibody Testing: A Visual Simulation or Virtual Reality
Source Institutions
In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.
The Earth's Timeline
Source Institutions
In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Wetlands
Source Institutions
Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

Mussel Your Way Through Photosynthesis
Source Institutions
Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

Ping Pong Ball Shooter
Source Institutions
In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

Diffraction
Source Institutions
In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

Rate of Solution Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

Variation Game
Source Institutions
In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.
