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 group or individual activity, learners are encouraged to watch birds near home or school—possibly where birds are nesting in a tree, pecking in a park, feeding from a feeder, or flying through

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.

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

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this activity, learners will collect, dry and press seaweed over the course of four days in a similar way that artists/crafters press flowers.

Investigate a flower's power of marketing by making an imitation flower that successfully signals a bee (or other pollinator of your choice) to visit.

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.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.

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

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
