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.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

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

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

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

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.
