In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.

In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh
