Drop Shape
Source Institutions
In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.

Sandy Samples
Source Institutions
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

Who Goes There?
Source Institutions
In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

Beachcombing
Source Institutions
In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

Web It!
Source Institutions
In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

Crayfish Investigations
Source Institutions
This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

Water Striders
Source Institutions
In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

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

Ocean in a Bottle
Source Institutions
In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

Size Wheel
Source Institutions
In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

Animals in a Grassland
Source Institutions
In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

Damsels and Dragons
Source Institutions
In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

Scent Tracking
Source Institutions
In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

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.

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

Out of Control
Source Institutions
In this outdoor activity, learners release a portion of a lawn from human control—no mowing, no watering, no weeding, no pest control—and then investigate the changes that result over several weeks.

For the Birds
Source Institutions
In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

Marine Skulls Cart
Source Institutions
In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.
