In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

In this activity, learners set up a night time insect observation station with a light and sheet.

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

Learners draw and describe a leaf, and then re-find leaves drawn and described by other learners. Learners can observe leaves outside, or leaves may be brought into the classroom.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

This activity (9th activity on the page) about hearing demonstrates to learners the importance of having two ears.

Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.

In this activity, learners collect worms and then observe how they move.

In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.
