Do Cities Affect the Weather?

In this activity, learners explore clouds and how they form. Learners compare the cloud formation in two bottles, one with air freshener and one without, to examine the importance of condensation nuclei. Learners will discover that pollution and dust in cities increase the number of condensation nuclei in the atmosphere, which can affect the local weather. This activity is written as a demonstration for a whole group, but can be conducted by individual learners.
