Let’s Discuss: How do shadows appear? Using the diagram in your workbook, describe one way light and shadows help us in our everyday life.
Link forward: Student design and conduct an experiment to test how brightness and color can affect our perception of the shadow generated.
Part 2: Create a system that forms shadows (10 mins)
Steps:
Step 1.
Turn on and pair:
- 1 RGB LED
- 1 Button/Virtual Button
Remind students they need to hold the on/off button down for a few seconds for it to turn on. A red light will appear once it is on.
Step 2.
Drag the RGB LED and Button onto the workspace.
The RGB LED block will enable us to create shadows from the light source
Step 3.
Add a Toggle block to the workspace.
