rubric for the boat project

Rubric for Staying Afloat Project


Exceptional (4)

Supported at least 1000 grams for minimum of 20 seconds
Report indicates proper measurements taken for the amount of foil used, area, weight and pressure of the boat.
Report clearly & logically discusses the procedure used to develop & design the boat Report clearly & logically discusses clearly & logically addresses problems that arose as well as solutions to solve. Words are spelled correctly. Punctuation & capitalization are correct. Scientific vocabulary is used.


Good (3)

Supported 750 - 999 grams for 20 seconds. Report indicates properly 2 out of the 3 required measurements. Report addresses procedure used to develop & design the boat. Few areas are unclear.
Some problems and solutions are discussed. Few areas unclear. Some spelling, punctuation & capitalization errors. Some scientific vocabulary is used.

Average (2)

Supported 500 – 749 grams for 20 seconds. Report indicates 1 out of the 3 measurements required. Some mistakes in measurements taken. Report overviews the procedure used to develop & design the boat. Some areas are unclear. Few problems & solutions discussed. Some areas are unclear and affect understanding
Many spelling, punctuation & capitalization errors that interfere with meaning. Few scientific vocabulary is used.




Still Working (1)

Supported under 500 grams for at least 20 seconds. Report does not accurately depict and/or report the amount of foil used or the area, weight and pressure of the boat. Report lacks details in regard to how the boat was designed. Information hard to follow. Report gives no information on problems and solutions experienced in designing the boat.
Spelling, punctuation and capitalization errors seriously interfere with meaning. Lack of scientific vocabulary.

extra credit for every 150 grams over the 1000 grams

model for boat write up

Model to Write the Report for
Staying Afloat Project.

Intro – These are the questions that need to be answered within this paragraph. An example below the questions is supplied as a reference.

Where did the ideas you used to design your boat come from?
What makes a boat buoyant, and how did this affect your design?

The ideas I used to design the boat came from ______. Knowing that for a boat to be buoyant it _______, therefore I needed to ______.


Body - These are the questions that need to be answered within this paragraph. An example below the questions is

What problems or obstacles did you face while constructing your boat, and how did you solve them? ( Describe and Explain)

As I constructed the boat there were _______ problems that arose, causing me to come up with solutions to these problems. The first obstacle was _________. To solve this problem I ______. The second problem I was faced with was _________. In this case I ____________.



Conclusion - These are the questions that need to be answered within this paragraph. An example below the questions is supplied as a reference.

How much tin foil did you use to construct your boat? ( total area )
What was the total quantity of mass your boat was able to support & for how long? ( in grams)
What is the area your boat takes up? measure bottom of boat ( L x W )
What is the weight of your boat? ( this should be done in class and recorded in Newtons ( to convert grams to Newtons - move decimal 2 places to the left ( dividing by 100 )
How much pressure does your boat exert of the surface of the water both with and without the load? formulas to follow to calculate this -


without the load : pressure = wt of boat/ area of boat ( answer recorded in n/cm2)


with the load : pressure = total wt of boat plus wt it held / area of boat ( answer in N/cm2)

In the end my goal was met, and the boat, which was made up of ________ of foil, was able to support a cargo of _______ for __________. It took up an area of __________ and had a total weight of ______________. As a result, the boat exerted _________ of pressure on the surface of the water without its load and ________ of pressure with its load.

buoyancy project guidelines

Staying Afloat

Objective : To construct a boat that can carry a cargo and float in
water.

Your boat should:
Be made of only aluminum foil
Support a cargo of 1000 grams without allowing any water to enter for at least 20 seconds.

Get started –
Begin by thinking about the shape of real ships and boats and what makes objects buoyant.

Requirements:

· You must keep track of how much aluminum foil you use. (LxW)
· Describe the process of how you developed and designed your boat.
· Record the area the bottom of your boat takes up and its weight using a spring scale.

Assessment:
· A rubric will be given to you on Wednesday, April 12, 2007
· You will test your boat in class on Wednesday, April 18 th

Project Due: Wednesday, April 18th
