STEM Challenge - How Many Pennies Can Your Bridge Hold?


Our STEM Challenge for the week focuses on engineering. Students in this challenge are going to build a bridge that can hold pennies.

We want to really challenge them and see if they can build a bridge out of straws, scotch tape, and index cards that can hold 100 pennies for at least 30 seconds!

Think you are up for the challenge?

What you need..

  • Straws

  • Scotch Tape

  • Index Cards

  • Scissors

  • Pennies

What you need to do...

  • Before students start building have each student brainstorm three ways they think might work for building their bridge to hold 100 pennies for at least 30 seconds.

  • Once students are done brainstorming have them pair up with another student.

  • In pairs let students discuss how they think they can build their bridge to hold the pennies.

  • Have each student choose one of their three brainstormed methods and give students all the materials they are going to need.

  • We recommend at least 10 straws and index cards per student.

  • When students are done building and they feel their bridge is ready to be tested have each student come to the front of the room and give their bridge a try to see if it meets our challenge!

We would love to see you try this STEM Challenge. Share your results with us through social media!

Happy Making,
