Procedure (how to go about the activity):

=20
Unknown macro: {text-data}=20
Unknown macro: {Go over force diagram of a boat, talk= about the most effective shapes for a boat. Have students draw their desig= n ideas. Distribute 1 square foot pieces of aluminum foil to each pari of s= tudents. After the first designs are complete, allow students to test wheth= er their boat floats. Redesign if needed. Final test should see how many pe= nnies the boats can hold.}=20

How can the EDP or engineering design practices be incorporated = into this activity?

Unknown macro: {text-data}=20
Unknown macro: {Testing the initial designs and then = allowing for redesign incorporated this part of the design process. Testing= the prototype and discussing how to improve designs is also part of the en= gineering design process.}=20

Comment: We completed this activity with 5th grade stud= ents. It went very well an the teacher was able to get involved with talkin= g about forces and the best designs for the boats. We had multiple tubs of = water for testing in order to speed up the process, but it may have been mo= re engaging to have one tub that all the students watched. This way the stu= dents could see what kind of designs were successful or not.
