This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

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

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.

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

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

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

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

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.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
