In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.

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.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Get all wrapped up in a lesson about skin!

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 make different shapes that hold exactly one mole of gas (air).

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

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

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

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.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

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