We have four rotations this week. During the first two rotations, you will have an opportunity to learn more about how bridges work by doing a webquest related to bridges. During the last two rotations, you will get started on building your bridge!
Bridges Webquest You are encouraged to work with one other person on this webquest. Do not work in groups of three or more! Each question is hyperlinked to a website where you can find the answer. Fill in the answer on your worksheet. 1. What kind of engineer builds bridges? 2. Name that bridge 3. Bridge Strengths and weaknesses (same as website #2 above) 4. Forces that act on a bridge 5. Sketch Truss Designs 6. Four Factors that Describe a bridge (same website as #4 above) 7. Forces Lab If you finish the webquest before the second day, please go back to the Cargo Bridge Virtual Bridge building activity and see if you can apply your newfound knowledge to improve your bridge building skills!

I have given you only a very brief overview of how bridge works. You learned in the video about how triangles are a common design feature. You also saw with the Tacoma Narrows Bridge what happens when you have an engineering failure. Try experimenting a little bit with different designs to see how far you can get in this virtual bridge building challenge. Just like a real engineer, you have constraints in terms of materials - how much they cost and what they can do. You can work independently or you can work with a partner on this virtual project. How far do you think you can get? Good Luck!

Over the course of the past month, we took the concept of the engineering design loop and what we learned from the catapult experiment and built our own catapults using limited supplies. We had several build days and two days of trials. The first day was a distance competition, seeing just how far we could launch marshmallows. Measuring where the marshmallow first landed, we had several groups that were able to launch over 6 meters (nearly 20 feet)! The next day, we had an accuracy competition, looking to see how close to a target they could get their marshmallow to stop. We had several students who could land their marshmallow within 6 inches of the target. Great work by all the teams. It's the perfect time of year to "drop everything and code". Not only is it National Coding Week, it is a great introduction to the concept of computer engineering. While we are not able to do any hardware engineering, students are hard at work learning the basics of computer coding. This week, they will have nearly 4 hours to finish as much of the introduction to coding course sponsored by Code.org.
