Lets Construct a Bridge!
1 ATTENTION GETTER
Teacher will show the students some images on different architectures such as Buildings, Streets, Malls and Bridges.
Teacher will distribute a thinking routine for students (see-think-wonder) and watch a video (http://science.howstuffworks.com/understanding-bridges-videos-playlist.htm)
2 DIRECT INSTRUCTION
Guest speaker will talk about how building is constructed. What are the essential materials should be used and considerations to take when constructing a building. Students will be digitally taking notes on evernote on their devices.
Students will share their questions/wonders on the class padlet page
3 GUIDED PRACTIC
Teacher will prepare 4 stations for the activity. Student will need to build a bridge from the material prepared in every station. the materials will be (papers, lego, cardboard and wood sticks).
Students will decide on the station they will work on. Students will collaborate to be able to design a durable bridge after sketching and designing its layout on sketchUp.
4 INDEPENDENT PRACTIC
Student will reflect on the design they have done individually and suggest how they can improve their design further.
Each group will share their design to the class and students will peer assess each other.
Students will fill a rubric designed by the teacher on Google form. Students will have to assess how the other group design was, as well as constructively criticize their structure.
