Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

Statistics: Steppin' Out
Source Institutions
In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

Going Green
Source Institutions
In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

Slowing the Flow
Source Institutions
In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

Up, Up, and Away
Source Institutions
In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

Breathing Room
Source Institutions
In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

Measuring and Protecting Skin
Source Institutions
In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

Heart and Lungs
Source Institutions
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

Temperature Tactics
Source Institutions
In this activity, learners explore the devices used over time to measure changes in temperature.

Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

Mapping the Homunculus
Source Institutions
In this activity, learners will explore how the human brain interprets environmental stimuli.

There's Always Room For JELL-O
Source Institutions
In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.
