Phet can be used to:

1) Introduce new concepts: PhET simulations can be used to introduce new scientific concepts to students, giving them an interactive and engaging way to explore and understand the topic;

2) Illustrate complex concepts: some scientific concepts can be difficult to visualize or understand through traditional instruction methods. PhET simulations can be used to illustrate complex concepts, providing students with a more concrete understanding of the topic;

3) Reinforce learning: after teaching a scientific concept, PhET simulations can be used to reinforce learning and help students apply what they’ve learned in a hands-on way;

4) Assessment: PhET simulations can also be used as a form of assessment, allowing teachers to test students’ understanding of a concept through interactive simulations and activities.
