Take a look at the final diagram here. Where do you think the motor is? Which part is the pulley?

Draw a diagram in your handout and label the important parts, while also sharing what you know about these simple machines.

Step 3: Engage & Enquire 构思与探索

Check out how it SHOULD work. This is the end goal. And if you have issues, bring your model to school in September and we will discuss what went wrong, and how we can make sure ALL the models work!

Answer the following question on your handout:

What part of the crane build was the most challenging or interesting for you, and why? 在组装过程中，哪一部分最有挑战性或最有趣？为什么？

4. Align & Apply 实践与应用

MrAlanL — 2024-06-06 08:42:03 UTC

If you have not built the crane model yet, ask for help! Then answer the following question:

Did you ask anyone for help or share your project with someone? What did you learn from that experience? 在过程中你有没有向别人寻求帮助或与人分享？你从中学到了什么？

If you didn't ask for help, what were the most important pieces of materials or information that allowed you to successfully build your crane? What skills did you already have?

Step 1: Catch and Connect 激发与连接

MrAlanL — 2024-06-06 08:42:03 UTC

Complete the section in your handout listed as "Catch and Connect". Then answer the following question.

Why do you think motorized cranes are important in real life? Can you think of where they are used? 你认为现实中为什么需要电动起重机？它们常用于哪些场所？

Step 5: Test & Trial 测试与评估

What happened when you first tested your crane? Did anything need fixing or adjusting? 第一次测试时发生了什么？你是否需要修理或调整什么部分？

If it all worked out on your first test, explain some of the tricky parts while building that you needed to pay special attention to.

Step 6: Exhibit & Extend 展示与拓展

Take your model and look at it to see what you would change to make it a better model. You can go back to the website linked in step 1! What challenges are there in using cranes in real life?

Don't forget to answer the following question in your handout.

How could you improve this crane model to lift more or work better? What would you add? 你认为如何改进这个起重机模型才能提升更多或更有效？你会增加什么？
