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

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

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.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.

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.

This is an activity where learners will discover what types and how many insects live in their own backyard.
