Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity about backyard habitats learners create a safe and toad-friendly environment near their own home.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

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

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

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

In this art-related activity, learners make a coin rubbing—a process similar to what archeologists may do with ancient artifacts. This activity can be used in connection with a history or art lesson.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

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

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

In this activity, learners will create their own coral polyps - the basis for a coral reef.

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.

Use this activity (13th activity on the page) to introduce learners to the sense of touch. Learners collect objects of varying textures like feathers, rocks, sand, etc.

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

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 explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.
