This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

This activity (located on page 3 of the PDF under GPS: Cave Swallows Activity) is a full inquiry investigation into bird behaviors.

This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

Learners follow a three-step process to start their own rock collection.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

In this activity, learners work in teams to study the observation skills essential to scientific research.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

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.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.
