Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.
Fungus Among Us
Source Institutions
In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.
Stuck on You: Adhesion
Source Institutions
Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
Investigating Sleep
Source Institutions
In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns.
All Mixed Up!
Source Institutions
In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.
"Can" You Stand the Pressure
Source Institutions
In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.
Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.
Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
Water Breathers
Source Institutions
In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.
Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.
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.
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.
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.
