"Physics - Packet 09 - Solids-Liquids-Gases - Answers.pdf"


Remember, quiz on this tomorrow, Friday, April 1st. 

Buoyancy Lab

Buoyancy Lab

1. Go to:
http://phet.colorado.edu/en/simulation/balloons-and-buoyancy
Click “Run Now!”

Learning Goals:

• Determine what factors make a hot air balloon or a helium balloon float.

Student Instructions: Follow the instructions and  ANSWER THESE QUESTIONS IN A WORD DOCUMENT AND EMAIL IT TO ME. dandrade@bridgeportedu.net

1. Why does a hot air balloon float even though it is so heavy?


2. What makes balloons float when they are full of air but not float when they are
deflated?

3. Starting with a hot air balloon, figure out how to make the balloon float. What
factors affect the balloon floating or sinking? Explain three of these factors and your
understanding of why this works as it does.

4. Move to the rigid hollow sphere. What does it mean that the sphere is “rigid?”

5. Play with the parameters of the simulation and get the sphere to float. How is the
sphere floating similar to and different from the floating hot air balloon?

6. How will you get the helium balloon to float? Explain how you plan to set all the
parameters to get the balloon floating.

7. Set the parameters as you predicted above. Did it work? If so explain why this worked.
If not explain why your predictions didn’t work and what you did to change it.

8. Summarize your findings, how does a hot air balloon that is so heavy float in air?

Fluids and Heat Labs for class today

•Go to: http://www.physicslessons.com/iphysics.htm 

–Fluids & Heat
Experiment 20 Density
Experiment 23 Pressure in Liquids
Experiment 24 Buoyant Force
Experiment 25 Ideal Gas Law

•

Instructions and what to hand in - put it all in a Word document with names and email to me. dandrade@bridgeportedu.net 

Lab 20 Density

–three objects on bottom (blue triangle, red/black square, red oval) - calculate density for each

–list which object(s) floated (try all of the objects)

•

•


Lab 23 Pressure in Liquids

–raise and lower manometer (red box with tube) and record depth and hydrostatic pressure

–do for all five liquids (water, ethanol, benzol, tetrochloromethane, and mecury)

–write down your observations of differences or similarities of the pressures at different depths

•

Lab 24 Buoyant Force

–lower the mass into the liquid and note the buoyant force as it is lowered into the liquid. Note how it changes until fully submerged.

–change the preselected values of base area, height and densities (do at least 6 trials)

–write down your observations of the different buoyant forces vs. the area, height and density

•

Lab 25 Ideal Gas Law

try it out and explore concepts 

Go to: http://www.physicslessons.com/qphysics.htm#qpf and answer the three questions

QUIZ FRIDAY!

On Friday, April 1st, all physics classes (periods 2,3,5,6,7) will take a quiz on Packet 9 - Density, Solids, Liquids, Gases. 


There are 5 problems on the quiz. You should review the packet and your notes. 


Reminder: the class notes are here:
https://sites.google.com/site/dandradeedusite/Home/physics-class-files
"Physics - Density-Solids-Liquids-Gasses - part one.pdf"
"Physics - Liquids lecture notes.pdf"
"Physics - Gases lecture notes.pdf"


There is also a copy of the packet on the same site. 


I will post all of the solutions to the problems on Thursday evening in case you missed any.

Bridges Project - pics

Go to this site:
https://sites.google.com/site/dandradeedusite/Home/physics-m-info/bridges-project 

for pictures of past bridges and an example sketch of a bridge with part counts and measurements.

Bridges Project

Bridges Project

You will start be exploring bridges and their structure:



WebQuest
–http://docs.google.com/View?id=d2rbhs8_1184fpz6r4gs

There are links on this site for you to go to also. You need to go to each of the links on the site. 

You should be taking notes and coming up with ideas for your bridge.



Bridge Links
•ces:
–http://www.bridgesite.com/funand.htm
There are tons of links on this site for you. Go through as many as you can. Take notes.




I will be checking the notes your group is taking about bridge design and construction. You must keep these notes written down and must have a drawn design before you may start construction.



---------------------------------------------------------------------------------------------

The requirements for the bridges you will build are listed below.

You must have a design drawn before you may start construction.



---------------------------------------------------------------------------------------------


Rules and Requirements


•Students will then build model bridges. The bridge that can hold the most weight wins.
–

Bridges have to be between 250mm and 300mm long and width must be between 50mm and 75mm wide.

The bridges must be less than 100mm high.
–

The only materials you will have are a knife, working surfaces, ruler, 15 pieces of balsa wood, and glue. The balsa wood pieces are 61 cm long and 4mm square.

You will not have to build any legs or supports - that will be done with books.

We will start building the bridges after you have done your research and designed your bridge.


UPDATED:

Your design should be well thought out. You should have drawing of your design (3 views - side, top, front). You should estimate how many different pieces of different size cuts of wood you will need.


You should also create a template where you can lay the wood on the paper and then glue it.
