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

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

Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.

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 activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

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

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

Students design and build their own parachutes in this hands-on engineering project.

In this engineering activity, young learners investigate multi-level buildings.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.
