Fold a Crystal
Source Institutions
Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

Beaded Braids: Investigating Patterns & Ratios
Source Institutions
In this activity learners create patterns of hair beads.

Boomerang
Source Institutions
Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

Attention!
Source Institutions
In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

Flower Powder
Source Institutions
In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.

Penny Rubbing
Source Institutions
In this art-related activity, learners make a coin rubbing—a process similar to what archeologists may do with ancient artifacts. This activity can be used in connection with a history or art lesson.

Moon and Stars
Source Institutions
In this craft activity, learners create a string of cut-out moons and stars.

Bee Builders
Source Institutions
In this activity, learners make a model of a beehive using simple materials.

Bird Feeder
Source Institutions
In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

Bird Nests
Source Institutions
In this outdoor activity, learners build bird nests and place them in the activity area, then play the role of naturalists as they try to locate each other's nests.

Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

Moo Glue
Source Institutions
Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

Wind Tunnel
Source Institutions
Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

Bird Feeders
Source Institutions
In this activity, learners build a bird feeder or feeders to attract birds for observation.

Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.

Sound Off!
Source Institutions
This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

Web Weavers
Source Institutions
In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.
