REMINDER – MRS. RYAN ABSENT ON TUESDAY Mrs. Vanover will be here. She is a former Akimel A-al Spanish teacher. Working on earning the marble jar treat time on Friday! For Tuesday – meet in 6th grade computer lab, sit at any computer for Tuesday ( there will be a seating chart in the future). You will work on a scavenger hunt for the class webpage, to learn where things are and how to get caught up when you are absent. Toward the end of class, Mrs. Vanover will have you “sign out”, and go over your answers. Make sure you turn your paper in for credit!

Creating Puffmobiles using the engineering design process!

The engineering design process It is a set of steps followed by engineers, to define a problem, brainstorm solutions, try the one you think is the best, then improve on it by making changes (doing ITERATIONS).

Criteria and constraints Engineers must work with: Criteria – the requirements of the design, or what it must be able to do. Constraints – the limits on the design, such as the cost of materials, the size, how much time to build, etc.

Making a puffmobile Your engineering challenge: Design a “car” using the criteria and constraints that follow, and see which puffmobile can travel nine feet with the FEWEST PUFFS OF BREATH!

What’s a puffmobile???!!?!

Video clip of puffmobiles in motion! Watch part of this clip to see young engineers collaborating while making a puffmobile! How do they share ideas? How do they receive them? How do you think they will handle disagreements? When you work with your group, what things can you do to help the engineering design process?

The criteria and constraints for the puffmobile Criteria: You may use the following: 3 straws 4 Lifesavers (do NOT eat!  ) – ALL WRAPPERS GO IN THE TRASH! 1 piece of paper 2 paper clips 50 centimeters of tape Constraint: You must move your puffmobile only by blowing on it.

Documenting your work In your notebook, draw a picture/sketch of your first puffmobile design. Use words and sketches to record each ITERATION (changes you made to your design) and why.

Storing your supplies to continue work next day… Each group will have a baggie to place their materials in. Write your baggie number down in your science notebook. Place all materials in the baggie, unless something won’t fit. Lay large pieces on top of your baggie and make sure your name is on them. Respect other groups’ baggies as you would want them to be careful near yours.

Brainstorm, choose a solution and begin working today. timeline Brainstorm, choose a solution and begin working today. Get half of next period to finish building and testing. Then we have the class road test, to see which puffmobile can go 9 feet with the fewest puffs to push it!

On your group’s turn, line up your puffmobile at the starting line. Road test! Use Level 1 voices! On your group’s turn, line up your puffmobile at the starting line. Choose ONE person from your group to blow on the puffmobile, to move it through the nine feet with the fewest breaths possible! We will record the results in a class data chart.
