One possible challenge that can be done in 45 minutes to teach the learning pit strategies to grade 8s is the “Marshmallow Tower Challenge.” Here’s how it can be structured:

Objective: To build the tallest freestanding tower using only marshmallows and toothpicks.

Materials needed: - Marshmallows (mini or regular-sized) - Toothpicks

Instructions: 1. Divide the students into small groups of 3-4. 2. Explain the concept of the learning pit and how it relates to problem-solving and critical thinking. 3. Provide each group with a set number of marshmallows and toothpicks. 4. Explain that they have 45 minutes to build the tallest freestanding tower using only the given materials. 5. Encourage the students to discuss and plan their tower design before starting to build. 6. Remind them to consider stability, balance, and structural integrity while constructing their towers. 7. Once the time is up, have each group present their towers to the class. 8. Measure the height of each tower using a ruler or measuring tape. 9. Discuss the challenges faced by each group during the activity and how they overcame them. 10. Reflect on the learning process and relate it back to the learning pit strategies, emphasizing the importance of perseverance, problem-solving, and learning from failures.

This challenge allows students to experience the learning pit firsthand as they encounter obstacles, make mistakes, and iterate their tower designs. It also promotes teamwork, communication, and critical thinking skills.
