In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
