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.

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

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

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.

Learners will understand the relationship between climate change and sea-level rise.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

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 build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

In this activity, learners make a device called a phenakistoscope, which displays a continuously looping animation consisting of images drawn onto a spinning disc.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

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.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

In this activity, learners use simple items to construct a device for indicating air pressure changes.
