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

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

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

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

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 make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

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

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

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

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

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

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

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

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

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

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 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 design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
