Teaching with one computer and a projector
Not every school has a computer lab. Many teachers have only their own laptop, or one projector shared between classrooms. You can still teach effective virtual lab lessons.
Make the class the scientist
The key is to keep students thinking, even though only one person controls the mouse.
- Show the question on the board.
- Ask for predictions with a show of hands or on mini whiteboards.
- Let students direct you: "Which equipment should I pick? What should I measure first?"
- Invite a student to the laptop for each new run.
- Everyone records results in their own exercise book.
Rotating roles
Assign roles for each run: one student operates, one reads the measurement aloud, one records on the board, and one checks the units. Rotate every few minutes.
Group tables
If you have a few phones or tablets with internet, groups can repeat the experiment with different values and report back. Compare results on the board.
Working offline
The labs run in a browser and need an internet connection during the lesson. If your connection is weak, test the lab before class and keep the lesson focused on one lab so less data is used.
Why it is worth it
Even whole-class virtual experiments help students picture equipment and processes they have only read about. Students remember what they predicted and saw far better than what they copied.
