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.

Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.

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.

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.

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

Dinosaur Homes
Source Institutions
In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.
Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.

Dancing Cereal
Source Institutions
In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

Air-filled (Pneumatic) Bone Experiments
Source Institutions
Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

Small Habitats
Source Institutions
In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
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.

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.

Fossil Dig Site
Source Institutions
In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.
