Building Background Door Adventures & Observations

The purpose of this activity is to increase students' awareness of design variations in common objects in their environment. 1. Ask the students to discuss the following prompts:
• Why do rooms have doors?
• What are doors made of?
• How many kinds of doors can you think of?
2. Ask each student to draw a picture of a door. Have the students share their drawings with the entire class. 3. Take your students on a tour of the school and ask them to observe all the doors they see. When you return to the classroom, draw a sketch on the board showing how the doors make a connection between rooms.

Steps for Learning Pet House Design

1. Show the students three pictures of floor plans at the following links, and ask them to locate the doors in each: 2. Divide the class into small groups and give each group a copy of the "Pet House Design" handout. Read the assignment aloud with your students and clarify any questions. Tell the students that they are using the steps of the design process to solve a problem. 3. Provide time for the students to share their work. Ask the students to explain their design to their classmates. Encourage the students to ask questions about the different designs, and how they generated ideas to solve their design task. Talk about how different students solved the doghouse design problem in different ways, and how there are many ways to solve problems.
