Scientists know about laws of nature that explain much about the world and the universe. They continue to learn by experimenting, and they make discoveries. They take nothing for granted. They may think an idea is true, but they test it over and over to prove it. When you earn the Scientist activity badge, you'll do scientific experiments and test some famous scientific laws. You'll explore ideas about how airplanes fly and the way changes in atmospheric pressure can move objects. You'll also experience the strange tricks your eyes and your brain can play on you. |
| Do These: |
| 1. Read Bernoulli's principle. Show how it works. |
| 2. Read Pascal's law. Tell about some inventions that use Pascal's law. |
| 3. Read Newton's first law of motion. Show in three different ways how inertia works. |
| And Do Six of These: |
| 4. Show the effects of atmospheric pressure. |
| 5. Show the effects of air pressure. |
| 6. Show the effects of water pressure. This may be combined with atmospheric pressure or with air pressure. |
| 7. Build and launch a model rocket with adult supervision. (NOTE: You must be at least 10 years old to work with a model rocket kit sold in hobby stores.) |
| 8. Explain what causes fog. Show how this works. |
| 9. Explain how crystals are formed. Make some. |
| 10. Explain how you use your center of gravity to keep your balance. Show three different balancing tricks. |
| 11. Show in three different ways how you eyes work together. |
| 12. Show what is meant by an optical illusion. |
| When you pass each requirement, ask your den leader or counselor to initial your Scientist scoreboard. |
