In this activity, learners build a carousel toy that spins when pushed down.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners explore the possibilities of clay as a natural material.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

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

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

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
