In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this math activity, learners make and explore patterns using the letters in their names, a grid, and some colors.

In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this activity, learners are challenged to design and construct a jointed figure that moves in a motion (something like jumping jacks) when a string is pulled.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

This activity has three story puzzles learners can solve to learn about life in the Arctic.

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 will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

In this activity, learners build small animated toys that move.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
