Instructions
Complete the following activities to learn about the efficiency of a pulley system and a trebuchet. Make sure to think critically and express your thoughts clearly.
Part 1: Pulleys
1. Describe how a simple pulley works. What is its purpose?
2. There are different types of pulley systems. List three types and briefly explain how each one works.
3. Conduct a simple experiment using a pulley. Describe your setup and the materials you used.
4. What did you learn about the efficiency of your pulley system during your experiment? Explain your reasoning.
Part 2: Trebuchets
5. What is a trebuchet, and how does it differ from a catapult?
6. Describe the key components of a trebuchet. Why are they important for its function?
7. Build a simple trebuchet using household materials (e.g., popsicle sticks, string, etc.). What materials did you use, and how did you construct it?
8. After testing your trebuchet, what conclusions can you draw about its efficiency? Consider factors like distance and accuracy.
Part 3: Comparison
9. Compare the pulley system and trebuchet based on their efficiency. In what situations is one more effective than the other?
10. Reflect on what you have learned about mechanical systems. How do these concepts apply to real-world machines?
