Introduction
In this activity you will build a bridge out of only the materials on the list provided in this activity. You will also need to follow the size limits on the list. This is an activity to teach you about physics and engineering as the builders will understand how some types of bridges are stronger than others, what different materials can support, etc.
Task
You will have to build a bridge to the best of your ability and it will have to be able to support a certain amount of weight. The grade you get will depend on how much your bridge can hold and if it follows the rules. Have fun and good luck!
Process
You will get into equal groups depending on how many are participating. When you have the groups, they will work together to build a bridge that follows the guidelines.
These rules are as follows:
- Bridge must be 10-12 inches long.
- Bridge must be only one segment. For example:
- Bridg must be able to hold 20-35 pounds.
- Bridge can only be made of popsicle sticks, wooden dowel rods, yarn, or copper wire and can be put together with a hot glue gun.
Evaluation
All bridges will have to go by the guidelines in the Process tab. If the bridge does not match the description, it will result in the teacher's choice of a grade.
If the bridge supports:
Over 35 lbs.(A)
35 lbs. to 31 lbs.(B)
30 lbs. to 26 lbs.(C)
25 lbs. to 20 lbs.(D)
Less than 20 lbs.(F)
Conclusion
Congratulations! You have successfully built a bridge made of household items! This might even lead to a career of architecture and building real bridges!
