In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

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 environmental health activity, learners investigate their own vital lung capacities.

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

Get all wrapped up in a lesson about skin!

In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

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

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

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

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

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

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

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