In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

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

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this engineering design challenge, learners build an air-powered spinning machine.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this activity, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.
