About the Science
- This experiment introduces the concept of how clouds form.
- It uses the hands-on activity to demonstrate how water vapor and condensation nuclei both need to be present for cloud formation.
- The experiment also has an extensional activity where temperature and pressure can be varied in order to see how those variables change the cloud formation process.
- Passed initial science review - expert science review pending.
About the Pedagogy
- This resource is a hands-on experiment that demonstrates how clouds form.
- During the experiment several assessment/discussion questions are provided in order to reiterate the scientific concepts. The questions lead to critical thinking about how clouds are formed.
- There are several other links for the students to explore, as well as another experiment.
- The combination of these materials should appeal to all learning types.
Technical Details/Ease of Use
- Extra links are added for further investigation.
- Some schools don't allow matches for the cloud in a bottle activity - alternatives like aerosol sprays can be used (a search will provide ideas for alternatives).
