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

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 how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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 fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
