Teacher Demonstration
Use the live model as a shared screen demonstration before students try their own predictions and observations.
Biology
I Saw The Cells!
Explore I Saw The Cells! as an interactive EJS simulation for biology.
1. Watch or Launch
Launch the Interactive
Open the simulation, adjust the controls, and compare what changes on screen before answering the concept-check questions.

2. Big Ideas
Key idea This interactive model helps learners test a prediction, observe the result, and explain the relationship shown in I Saw The Cells!.
What Students Can Learn
- Identify the main controls and the visible output.
- Change one setting at a time.
- Compare two cases using evidence from the screen.
- State the concept or rule shown by the model.
Guiding Question
What relationship does the model help you see more clearly?
3. Try the Investigation
Predict
Choose one control and predict what will happen before changing it.
Observe
Change one setting and describe exactly what changes on screen.
Compare
Test a second setting and compare the two outcomes.
Explain
Use the evidence from the model to explain the concept or rule being illustrated.
4. Teacher Notes
Lesson Use
Use the simulation as a short inquiry activity: predict first, change one control, observe the result, then explain the relationship shown by the model.
Discussion Prompts
Ask learners what changed, what stayed constant, what evidence they used, and how the model helps them explain the concept more clearly.
5. Concept Check
These questions are generated from the topic and the concept illustrated by the simulation. Use them after students have explored the model.
