Class Lava Crossing Challenge: Hot Problem Solving

Suggested materials for the entire class to share:

• 4 baseball base plates or square pieces of cardboard (~12 x 12 inches, or .3 x .3 m)
• string or rope, ~20 feet (6 m)
• duct tape
• 2-4 small buckets
• clipboard and paper to write down the problem statement and record brainstorming ideas
• (optional) Design & Brainstorming Handout (PDF)

Note: Limiting the amount of materials limits the choices for solutions. So, the more materials made available to the students, the more interesting the activity.
