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.



Key Terms



• 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

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

B - Dimension the overall height (either the front or side view)

C - Dimension the overall width (either the top or side view)

D - Dimension any other edges, cut-outs, slants, holes, etc. (don’t over dimension, it only makes the drawing look messy)

A- Draw the side view of the shape in the bottom right corner of the sketch box (over one up one)

B - Starting at point #1, draw a diagonal line up to the left 5 intersections. (take your time and hit each diagonal intersection)

C - Repeat step B for points 2, 3, 4, and 5.

D - Now simply connect all 5 dots and your isometric view will be complete.

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.
