Here are some example SMART Goals, choose 1 and make it your own.
#1: In the next 5 days, we will use balsa wood and glue to design and build a truss bridge that will hold at least 20 pounds.
#2: In the next 5 days, we will use balsa wood and glue to design and build a truss bridge that will be 14 inches long, 3 inches wide and will hold 25 pounds.
Vocabulary:
pier truss
span beam
arch support
suspension
Work your way through the slideshow for step-by-step instructions to a successful bridge!
Teamwork and time management are so important on this project. Everyone on the team should be doing something at all times in order to get this project completed on time!
Things to consider before writing your SMART Goal-
What type of bridge are you going to design?
How much weight do you want it to hold? (A ream of paper is 5 pounds.) The New STEM Lab record is 60 pounds, set by Evolet, Adie and Meritt from Mrs. Kelley's 5th grade class!
How long does your bridge need to be (minimum) to fit across the bridge testing table?
Design and build a bridge or structure with balsa wood. Test the strength of your design on the bridge/structure tester table.
Day 1: Complete design and sketch ideas. Complete a three-view sketch (top, bottom and side) of the bridge/structure you plan to build. (Watch video for build procedure.)
Day 2: Build side #1(Includes cut, pin and glue joints)
Build bottom and top (Includes cut, pin and glue joints)
Day 3: Build side #2 (Includes cut, pin and glue joints)
Day 4: Assemble all sides together to dry for presentation. (Use large black clips to hold pieces together after gluing.)
Day 5: Test the model you designed.
