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.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

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

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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