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

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

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

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

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 computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.
