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.

Kimchee Fermentation Chamber
Source Institutions
Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

Conservation of Mass
Source Institutions
This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

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.

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.

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.

Plants Around a Building
Source Institutions
In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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

Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

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.

Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

Shaking It!
Source Institutions
In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

Production of a Gas: Controlling a Chemical Reaction
Source Institutions
Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.

Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.

Using a Sundial
Source Institutions
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Cool Tool
Source Institutions
In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

Energy For Life
Source Institutions
In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.
