You and a friend have been asked to help design a playhouse for a new park. Your job is to evaluate and recommend materials for different parts of the structure. The playhouse will be out in the direct sun during the day, where summer temperatures can reach 34°C (93.2°F). You must consider how materials transfer heat as you make your choices.

1. What kind of materials do you think would be best to use to build different parts of the playhouse? Explain your reasoning.
