In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore how salt water freezes in comparison to fresh water.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

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.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity, learners will explore the water cycle by creating a small atmosphere.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

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 three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
