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

Materials needed: - 20 spaghetti sticks - 1 marshmallow - 1 roll of masking tape

Instructions: 1. Divide the students into small groups of 3-4. 2. Provide each group with the materials mentioned above. 3. Explain the challenge: The goal is to build the tallest freestanding tower using only the spaghetti sticks, masking tape, and the marshmallow. The tower must be able to support the weight of the marshmallow on top. 4. Set a time limit of 30 minutes for the construction phase. 5. During the construction phase, encourage the students to brainstorm ideas, plan their tower design, and work collaboratively to build the tower. 6. After the construction phase, have each group present their tower to the class, explaining their design choices and any challenges they faced. 7. Test the stability of each tower by placing the marshmallow on top. Measure and record the height of each tower. 8. Facilitate a class discussion about the challenges faced during the activity, emphasizing the learning pit strategies such as perseverance, problem-solving, and resilience. 9. Conclude the activity by highlighting the importance of learning from failures and embracing challenges as opportunities for growth.

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