Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

In this activity, leaners build their very own rainsticks, an instrument filled with pebbles and seeds that create sounds like falling rain. Save costs by using material found around the home.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

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

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

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 (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this family or group activity, learners create a nature journal by visiting a local nature center or backyard, observing creatures in their natural habitats, and sketching what they see.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

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