Rearing Monarchs
Source Institutions
As a long-term project, you can rear monarch butterflies at home or in a classroom.

Crash Landing!
Source Institutions
In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

Spaghetti Bridge
Source Institutions
Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.

Egg Osmosis: A four day eggsperience!
Source Institutions
Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

Build a Big Wheel
Source Institutions
In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

Yeast Balloons: Can biochemistry blow up a balloon?
Source Institutions
Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Joe's Place
Source Institutions
In this math activity (Page 8 of the Dining Out! PDF), younger learners select items from a menu and count out the total amount needed using the fewest bills and coins possible.

Jiggly Jupiter
Source Institutions
In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

Temperature Affects the Solubility of Gases
Source Institutions
In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.
How Does Water Climb a Tree?
Source Institutions
In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

Ziptop Bag Chemistry
Source Institutions
In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

What's in the Water?: Biotic and Abiotic Elements in Aquatic Ecosystems
Source Institutions
In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

Instant Ice Cream with a Dry Ice Bath
Source Institutions
In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

Number of Mentos vs. Height: Soda Geyser Series #5
Source Institutions
In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

M&M's in Different Sugar Solutions
Source Institutions
In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

Green Travelers
Source Institutions
In this activity (on pages 23-29), partners use the Plant Traveler Cards, along with a world map and map worksheets, to follow plants such as cassava, chocolate and coffee that grew first in one part
