Starting from this week we are going into a 3 weeks series of teaching the students how to build a bridge. There are some basic requirements for building our bridge: 1. The construction shall not use more than 50 popsicle sticks; 2. The bridge should span at least 12 inches; 3. The width of the bridge should allow a tennis ball to row over it easily; 4. There should be a stable flat surface on it allowing cookie sheets to lay on for testing purpose; 5. The bridge should be able to take as much weight as possible. In this week's lesson, we are going to initiate the building process. The key question to ask is: 1. Purpose of building a bridge; 2. Common features of a bridge; 3. Destructive events for a bridge and precautions accordingly. Next, we are going to distribute the materials to the students and start the design process. The students shall draw their design before the actual construction. After the design is completed, we will help the students to build their bridge and label them for next week's tests.

Construction on bridges moved slowly this week. Some groups were able to complete a bridge. We also tested our example bridge which held over 36 pounds.
