Zero in on an interesting resource involving radar technology. Groups construct a radar sensing unit and learn to calibrate the system. Using the radar system and the Pythagorean Theorem, they calculate distances between objects.

The Diary of a Wimpy Antenna? In the last installment of a six-part series, your class constructs a model of a radio antenna and tests its torque. Pupils use the results to design a better model that resists bending and twisting forces.

We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

Learners practice relating rules of trigonometry and properties of circles. With a few simplifying assumptions such as a perfectly round earth, young mathematicians calculate the lengths of various paths between satellite and...

Every time a bell rings ... there is lightning in the area. The activity provides directions to build a model of a lightning detection system. Similar to a system designed by Benjamin Franklin, the system uses static...

Challenge young meteorologists to apply their knowledge of weather to build their own weather stations. The resource provides the directions to build a weather station that contains a wind vane, barometer, thermometer, and rain...

In which direction is traffic moving faster, north or south?  Use box and whisker plots to organize data and interpret the results. Detailed solutions are included. This activity would be good as a warm up or quick assessment at the...
