This is a simple and fun activity for learners to explore water and colors.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

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 two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

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

In this art activity (page seven of the pdf), learners will use their creativity to make a "motion collage." Each student will be encouraged to draw a picture of something that moves to be a part of t

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

How many colors make black? Gather as many water soluble black markers as you can find.

In this activity, learners craft their own model of a comet on a stick to make it fly around the room.

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

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.

This activity is a fun way to show two stages in a Monarch butterfly's life cycle. Learners will create an optical illusion that can be flipped from caterpillar to butterfly.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners will create their very own constellation.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.
