DESIGN CHALLENGEDESIGN CHALLENGE
Design and build a boat that that can hold as many passengers (pennies) as possible and move across the water tank on its own power. Design and build a boat that that can hold as many passengers (pennies) as possible and move across the water tank on its own power.
Criteria Constraints
You boat must... Be able to hold at least 20 pennies without
sinking Float on the water and be stable (buoyant) Be able to travel from one end of the water
tank to the other under its own power
You boat must stay within these limits: Maximum Length: 20.5 cm Maximum Width: 25 cm
Approved Materials Key Points
• 2 foam blocks • 1 propeller• 1 motor• 1 battery• 1 wooden platform• 1 switch• 1 battery holder• 2 wires• Mechanical fasteners (screws, nails, bolts, etc.)• Glue
NOTE: Keep track of and safeguard all materials. Points will be lost if replacement parts are needed.
Objects that are lighter than the same amount of water will float.
Objects that are heavier than the same amount of water will sink.
• 2 foam blocks • 1 propeller• 1 motor• 1 battery• 1 wooden platform• 1 switch• 1 battery holder• 2 wires• Mechanical fasteners (screws, nails, bolts, etc.)• Glue
NOTE: Keep track of and safeguard all materials. Points will be lost if replacement parts are needed.
Key Terms

NOTE: Keep track of and safeguard all materials. Points will be lost if replacement parts are needed.
• Buoyancy- the tendency of an object to float.• Drag-the force that slows down or prevents an
object from moving.• Hull- the body of a boat.• Stern- the back of the boat.• Bow- the front of the boat.• Beam- the width of the boat from side to side at the
widest part.• Port- the left side of the boat.• Starboard- the right side of the boat.
Class CompetitionClass Competition
Race Day Rules:1. The boat will be released by from the end of the tank with the boats’ stern (back) touching the wall.2. The launcher must release the boat without providing any force.3. The timer will start when the boat's stern (back) leaves the dock (back of tank) and ends when the bow touches the opposite end of the tank.4. The boat may hit the sides of the trough or take on water without disqualification, but all parts of the boat must finish together.5. The boat must remain in contact with the water at all times6. The winning boat will be the one with the best figure of merit (finishes the course in the shortest time with the most passengers). In the event of a tie, another time trial will be run to break the tie. No repairs or modifications will be allowed for re-trials.

ENGINEERING YOUR PROTOTYPE
All transportation vehicles have sub-systems or parts that work together to make them go. The scooter on the right has a motor for PROPULSION, a handle bar for GUIDANCE, a hand brake for CONTROL and a wheel for SUSPENSION.
A) Identify each of the same sub-systems parts in your prototype
PROPULSION: ______________________________________
GUIDANCE: ________________________________________
CONTROL: _________________________________________
SUSPENSION: ______________________________________
DRAG the force that slows down or prevents an object from moving.
B) Which of the vehicles below will likely produce the least drag? _____
C) How are you going to reduce drag in the design and building of your prototype? (Complete sent.)

IDENTIFY THE PROBLEM
In your own words... state what you’ve been asked to do.
I have been asked to ___________________________________________________________ that will
_____________________________________________________________________________________
Look at the rubric for this project on the last page and then answer the next two questions.
1. Which category do you think will be the most challenging? ____________________________________
2. What’s ONE strategy you can try to overcome it? ____________________________________________
_____________________________________________________________________________________
DEVELOP POSSIBLE SOLUTIONS
In the boxes below, draw six (6) different versions of what your design might look like. It’s very important to label the drawing to help me understand your thinking.
Prototype #1 Prototype #2
Prototype #3 Prototype #4
Prototype #5 Prototype #6
5
CHOOSE A SOLUTION
Identify which prototype you’ve chosen to make and explain why. If you really can’t describe it to me and tell
me why this prototype is insanely great, you shouldn’t be building it.
CHOOSE A SOLUTION
A paragraph has a beginning a middle and
an end.The beginning, or the topic sentence, states what the paragraph is about.
The middle develops the idea in detail by giving specific support & details
for it (usually 3 - 5).
The end (conclusion) restates the main idea in the topic sentence.

CHOOSE A SOLUTION
You need to create clear, specific and labeled drawings (using rulers and other drawing instruments) from three different views (front, top and side). Draw the designs in centimeters and label the dimensions. You will not be able to begin construction until this drawing is completed. Teacher’s initial are required for approval. Follow the examples below.
A - Place a point of origin 3 blocks over and 3 blocks up
B - Draw in the object line representing the overall length (3inches or 12 blocks)
C - Draw in the object line representing the overall height (2 inches or 8 blocks)
D - Finish drawing the object lines that represent the outside edges of the shape
E - Measure and draw any other object lines that represent more surfaces

PROJECT RUBRIC
____ Your prototype exceeded the goal and
worked perfectly every time it was demonstrated.
____ Your prototype met the goal all or most of the time it was demonstrated.
____ Your prototype’s performance was
inconsistent and partially met the goal when
demonstrated.
____ Your prototype did not meet the goal or was not able to be demonstrated
____ Your prototype is exceptionally sturdy and well
made. The joints and any moving parts precisely fit
together (nothing wobbles, shakes, jiggles or vibrates).
Surfaces are smooth, rounded and even; no dents, gouges, chips, globs of glue, scratches or machine marks.
____ You chose, used and kept track of tools and
materials very effectively without any safety reminders
or replacement parts. You pushed yourself even when
problems came up and it was difficult to figure out a
solution.
____ Your prototype is solidly made and holds
together. The joints and any moving parts all fit together. Most surfaces are smooth;
curves are rounded and even and there are few, if any
dents, gouges, chips, globs of glue, scratches or
machine marks.
_____ Your prototype has some parts that don’t hold or fit together; surfaces are not
all smooth, curves not rounded and even and it’s got some dents, gouges,
chips, globs of glue, scratches or
machine marks.
_____ Your prototype is rickety; nothing really fits together well. Surfaces are
unfinished, damaged or improperly formed and frequent repairs and
replacement parts were needed.
____ Your design brief clearly shows how hard you thought about, planned and
followed the engineering design process, drawings and building guide while making
your prototype.
____ You chose and kept track of tools and materials
and used them without many safety reminders or replacement parts.
You tried to solve your own problems before asking
for help.
____ Your choice, use and care of tools and materials
was sometimes careless. You needed some replacement parts and safety reminders
and had trouble solving problems on your own.
____ Your choice, use and care of tools and materials was careless. You needed
replacement parts and stopped working when there was a problem and waited for others do the work for you or tell you what to do.
____ Your design brief shows that you thought
about, planned and followed the engineering design process, drawings and
building guide while making your prototype.
____ Your design brief shows somewhat that you
thought about, planned and followed the engineering
design process, drawings and building guide while making
your prototype.
____ Your design brief doesn’t show that you
thought about, planned and followed the engineering
design process, drawings and building guide while making
your prototype.
