Got Seaweed?
Source Institutions
In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

Flocking for Food
Source Institutions
In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

Candy Chemosynthesis
Source Institutions
In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

Edible Earth
Source Institutions
In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

Edible Soil
Source Institutions
In this yummy activity about soil (page 9 of PDF), learners will create layers of soil using food. They will learn about the composition and role of each layer.

Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

Grow Rock Candy
Source Institutions
Learners grow sugar crystals (rock candy). They make a hot solution that has an excess of sugar dissolved in it, then as the solution cools, they see sugar crystals form.

Algae in Excess
Source Institutions
Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Who Can Harvest a Walleye?
Source Institutions
This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

Recipe for a Moon
Source Institutions
In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Bury Me Not!
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

Single Serving Volcanism
Source Institutions
In this activity, learners eat a snack and make a model of the plumbing system of a volcano.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

Making Waves
Source Institutions
Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.

Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
