In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

Learners make their own simple slide rules out of paper and learn how they work.

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

In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners take on the role of environmental engineers as they design water filters.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

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

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

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 explore how wind energy can be generated on both a large and small scale.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
