Make your own spin art device using an old record player! Notice patterns and effects the spinning movement has on your work. When finished, post your work to the Spin Art Gallery!

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

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

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners overlap the three primary colors to see how all other colors are made.

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.

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

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

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

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.

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

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 sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.
