Terms
Temperature: Measures the amount of heat energy something contains
( average kinetic energy)
Thermal Energy : measures the total kinetic energy of all the particles in a
substance.
degree Celsius: basic unit of measurement for temperature in the Metric
system.
degree Fahrenheit: basic unit of measurement for temperature in the English system.
Absolute Zero: temperature at which there is no heat energy. No
molecule movement. Used by scientists in extreme
conditions.
Conduction: The transfer of heat through a solid; direct contact
particle to particle within a substance.
Convection : The transfer of heat through a fluid ( gas or liquid) - currents
Radiation : The transfer of energy through empty space in form of
electromagnetic waves.
Specific Heat : The amount of heat required to raise the temp of a
Substance
The higher the specific heat the longer it takes to heat up.
The higher the specific heat longer it takes to cool down.

Straw Structure Lab Packet
Name: _____________________ Date: ___________
Science 6 - ______ Lab # _______
Constructing a Straw Structure
Problem: How can we construct a straw structure at least 1 meter high that is able to
stand on its own and withstand at least 250 grams of mass at its highest
point for at least 1 minute?
Pre – Lab questions to discuss.
Jot down answers in your lab book.
1. What are the best shapes to use for a tall structure?
2. What kinds of support does your structure need to continue standing
as you build up?
3. What are some good ways to build a foundation, or base, for a tall structure?
4. If you were going to design a building, how would you determine how strong
it would need to be?
5. How do you think the material from which a building is made affects its strength?
Gather Information:
As a group discuss what different types of straws and paperclips you could use and write down this information below.
Discuss the different shapes you could construct and possible number of straws and clips you plan on using in your structure. Meaning do you think you should use a lot or minimize the amount? Write this info below.
Paper Clips Straws Shapes Quantity
Form a Hypothesis:
Sketch your group’s design plan below and develop a hypothesis that is a suggested solution to the problem stated above. Write this hypothesis on the lines provided below.
Ex. - If we use straight straws and small clips with a big base, than our structure will be able to stand and support more than 250 grams.
Hypothesis:
Record and Analyze your Observations
At the end of each period (~ 5 minutes prior to the bell ringing) sketch your structure and count the approximate number of straws and paper clips it is made up of. Record these numbers on the side of your drawing. Jot down observations you are making in regard to your structures durability to stand on its own and later withstand weight.
Analyze your drawing and notes each night and write down one or two ideas on how to improve your group’s structure. Share these thoughts with one another the following day and continue to work on meeting your goal.

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
