Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Space Stations: Bones of Contention
Source Institutions
In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
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.
How Many In a Minute
Source Institutions
In this activity, learners will keep track of how much they can do in one minute. Instructors can pick something everyone will do for a minute, such as jumping up and down or drawing stars.
Aerogel
Source Institutions
This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.
Valves and Pumps: A Demonstration
Source Institutions
This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.
How can You Demonstrate the Efficiency of Different Light Bulbs?
Source Institutions
In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.
Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
What is a “Convection Cell”?
Source Institutions
In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.
Updrafts in Action
Source Institutions
In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.
Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
Ready to Observe: Enhance Your Telescope Experience
Source Institutions
This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
How it is Currently Done
Source Institutions
In this quick activity, learners observe how wind creates ocean currents.
Mystery Matter
Source Institutions
This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.
