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

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, young learners (2 years and up) explore flower and plant biology and pollination by planting seed in a homemade seed starter.

In this activity, young learners (2 years and up) explore dirt and what is in it by painting with mud.

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

In this activity, young learners, (2 years and up) explore bird behavior and adaptations by providing a homemade bird feeder and observing birds.

In this activity, young learners, (2 years and up) explore animal behavior and adaptations by providing a "track trap" and observing the signs animals leave behind.

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners will trick out their bike with crafts and flair. Learners will explore symmetry, cause and effect and design through this activity.

In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

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

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.

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

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

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

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.
