STEM Challenge: Wheely Axellent!

Build a Merry-Go-Round

Context for Challenge

Students go on a time-traveling adventure to ancient Mesopotamia, circa 3500 B.C.E., where they meet Nasaba, an innovator who revolutionized pottery making with the world’s first wheel and axle. They must build a merry-go-round using the principles of the wheel and axle introduced by Nasaba.

Constraints and Success Criteria

The constructed merry-go-round must use a wheel and axle and be capable of spinning at least three times with a single push, without any additional force.

The success of the merry-go-around will be determined by its ability to spin freely at least three times after being given a push, showcasing the effective use of the wheel and axle design.


Materials
Final M1-4 Materials

You do not need any testers for this challenge.


Set Up

  1. Prepare Materials: Ensure you have all the necessary materials ready beforehand and organize them so that they are easily accessible to students. Students should use no more than five of any one material per creation! For example, a student can use five straws and five pieces of paper, but not ten straws. If you provide aluminum foil, no more than one arm’s length piece for each student!
  2. Provide Guidelines and Constraints: Reiterate the challenge to students, as needed. Building time is 45 minutes!
  3. Model the Design Process: Before students begin, demonstrate the design process by going through the steps yourself. Discuss how to brainstorm ideas, create prototypes, test them, and make iterations based on the results, as needed.
  4. Encourage Collaboration: Foster a collaborative environment where students can work together in pairs. Encourage them to share ideas, help each other troubleshoot challenges, and provide constructive feedback throughout the process. But no groups of three!
  5. Support Adaptation: Encourage students to embrace the mindset of adaptation and problem-solving. Help them see that setbacks and failures are opportunities to learn and make improvements. Guide them in identifying areas for adaptation and brainstorming alternative solutions.
  6. Facilitate Reflection: Set aside time for students to reflect on their design process and decision-making. Ask questions that prompt them to think critically about their choices, challenges they faced, and what they learned from the experience. This reflection can be done individually, in pairs, or as a whole-class discussion.
  7. Celebrate and Showcase: Celebrate students’ efforts and showcase their work.

CASEL Discussion Questions

Five questions aligned to Social Awareness and Relationship Skills — our focus CASEL competency for Module 4 and Module 5 —  for teachers to foster an engaging discussion and social-emotional learning

  1. Discuss the importance of respecting and acknowledging contributions from diverse cultures to our current knowledge base. How does this foster social awareness?
  2. How might Nasaba have felt introducing her invention to others? Why is it important to recognize the feelings and achievements of those who came before us?
  3. How can we apply the principle of reducing friction in relationships, similar to how it benefits the wheel and axle?
  4. Discuss the significance of inventions in bringing communities together or driving them apart. Can you think of a modern example?
  5. Nasaba was initially dismissive of Special Agent L. What could this tell us about the importance of patience and open-mindedness in our interactions?
