2. Now that you have studied these important architectural terms, you are going to complete a scavenger hunt to demonstrate your understanding.
3. Now we are going to learn about and use shapes that make structures strong, first focusing on compression and tension. You will need a small group of 4 people ideally. If you have an odd number of people, repeat some of these exercises so that everyone has a chance to try it.
4. In your small group, get a bag containing straws and paper clips. Think click on the link below and follow the directions.
- Straw Shapes Handout
- Now that you have finished the Straw Shapes activity, identify the areas in each shape that experience tension and compression when a load is placed on top of the shape.
- Explain why the triangle is stronger than the square in terms of the distribution of tension and compression.
- In your small group, gather masking tape and newspaper. Build a "chair" out of these materials that will support your weight when you sit on it. Do not be wasteful with the tape. Discuss why something so flimsy like newspaper can be strong enough to hold your weight.
6. Now it is your turn to pick an engineering challenge of your choice. You must work with a small group of 3-5 people. Choose wisely. You must be able to work cooperatively together and not distract each other. These challenges require you to think critically and be creative. You must problem solve in order to complete it. Some of the challenges require very few materials while others require quite a few. Think about this while your group picks your challenge. As a group, you are responsible for getting all of your needed supplies. I will not be providing your supplies. The links provided to the engineering challenges are lesson plans for teachers. You will be your own teacher, so your group will need to use the provided lesson plans to teach yourselves what to do. There are student resources as well. Your group will need to use both. There are 16 different challenges/lesson plans to choose from. Carefully look them over and submit in writing the members of your group, the challenge selected, the materials you will need, and how you will provide the materials. You will have until the end of the first week in May to complete your engineering challenge. If your group finishes early, please choose another challenge to work on.
