Moving Water without Touching it - Lab Activity Disclaimer: This activity is a customized version of the experiment found in the textbook with permission from Wiley

Learning Goals:

Students will be able to:

1. Improvise and build small physics experiment from household items
2. Observe and describe physical phenomena
3. Relate everyday life events with physical theories

Experiment:

Unlike gravity, which always pulls objects toward one another, electric forces can be either attractive or repulsive. You can experiment with electric forces using a thin stream of water and an electrically charged comb.
