- Have students observe and learn about LEDs
- coin cell batteries
Let's Get Started!
You can learn a lot about electronics by observing the components carefully. Here are some questions that you can think about as you play with LEDs.
1. Why do you think the LED has a short leg and a longer leg?
2. How many LEDs can you glow using a coin cell?
3. Why do you think the Blue LED stops lighting up when we add a Green or Red LED?
