In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.

In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.

In this activity, learners will trick out their bike with crafts and flair. Learners will explore symmetry, cause and effect and design through this activity.

This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

In this optics activity, learners investigate afterimages.

In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

In this activity, learners will use their nose to sniff out hidden scents using extracts and cotton balls. Activity includes materials list, game instructions, STEM connections and more.
