In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

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 engineer a new shape and use it to create a new pattern with no wasted space.

Up close, an array of dots could look random, but take a step back, and an image forms. By tracing over an image, learners can create their own dot based image.

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 activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

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.

In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.

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

In this activity, young learners (2 years and up) explore turtle basic adaptations and biology. Turtle external anatomy is explored by "building" a turtle with a nature collage.

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

In this activity, learners will go outside and create a constellation.

In this activity, learners will become an engineer by designing and engineering a miniature parachute.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.

In this outdoor activity, learners will gather natural materials outside that they think a dinosaur would want to lay its eggs in.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.
