2. Make your hypothesis: How do you think different light sources will affect shadow length and size?
3. Identify the variables in our investigation:

Independent variable (what we will change): ________________________

Dependent variable (what we will measure): ________________________

Controlled variables (what we will keep the same): ________________________

4. What safety risks should we consider when working with light sources?

8. Which light source created the longest shadow?

Torch

LED Lamp

Natural Light

🤔 Part 3: Analysis and Reflection

9. What patterns did you notice in your results? Explain what happened to shadow length and size with different light sources:
10. How did you make sure your test was fair? Give two examples:

1. ________________________________________________

2. ________________________________________________

11. How did your group demonstrate the RISE values during this investigation?

Respect: _________________________________________
