Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

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

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

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t

This is an online game about the complexities of farming. Learners will "draw" cards and make decisions about how to take care of their farm.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

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 a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

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 build unique sound enhancing inventions with items from around the house to amplify sound from their smart phone's speakers.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

In this activity, learners learn about the adaptations that flowers have developed which support pollination. Learners also list their personal preferences (i.e.

In this activity, learners act out the flow of blood in the human body! A great way to get learners up and moving while learning about the circulatory system.
