In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

In this activity, learners use their imaginations and picture a scene in their heads.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this math lesson, learners rotate through six estimating and measuring centers. First, learners read the book, "Room for Ripley" by Stuart J.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
