Learners write a message in Braille using beans to form the patterns of dots. Learners glue beans in place, and then challenge another learner to read the message.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity learners will build a neighborhood out of blocks and cardboard.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners explore sports engineering and advanced materials development.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.
