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 mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.

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 try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

Coins are everyday objects which tell a lot about the people who use them.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

In this activity, learners build small animated toys that move.

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

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

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

In this design challenge activity, learners build a four-stringed instrument that can play a tune.
