Assignments for Friday, March 30, 2012

Hi everyone,

I'm still really sick with bronchitis. Here are your assignments for Friday, March 30th. Have a great weekend.

All physics classes (Periods 1, 3, 4, and 6)

Online Labs

http://www.physicslessons.com/iphysics.htm

Fluids & Heat

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 four 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

Each group turns in ONE paper for the entire group. Make sure all of your names are on it.

Assignments for today, Thursday, March 29th

I am absent today with severe bronchitis. Here are your assignments.

Period 1 - Packet #9, Problems 10-17
If you lost your packet, it is also posted on the class site where the lecture notes are located.

Period 3 - In red Physics book (Glencoe Physics) on bottom shelf in back corner of room.
Chapter 13, States of Matter (pretty sure that is chapter number, definitely title of chapter)
Practice Problems in chapter: 1, 5, 9, 13,17, 21
Make sure you put the books back on the shelf at the end of the period

I will check the work when I come back. You do NOT  have to turn it in to the sub, but don't lose it either.

Fluids Homework

The lecture notes for the 1st part of fluids were posted yesterday (see post below).

The homework is Packet 9, #10-17.

If you lost your Packet #9 you can access a digital copy of it here:

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

However, do not ask to print it out in my room. Print it out somewhere else, or just do the answers in your notebook while viewing the packet online.

Prizes at each grade level

Second Prize: Kindle or eBook device
Third Prize:Season pass to one of the following museums: Stepping Stones Museum for Children, The Discovery Museum or CT Science Center
Honorable Mention: Energy-Saving Gift Bag

Labeling

Each entry should have the following information typed or neatly printed at the top, left-hand corner of each page, Student Name, Grade, School, Town, Teacher’s Name, School Telephone

High School Grades 9-12 Contest Challeng –

Reducing Your High School’s Carbon Footprint

Write a letter to your principal about what you and your fellow high school students can do to address the problem of climate change in your high school. What actions can you take to reduce the school’s carbon
footprint? Be sure to include a comprehensive carbon footprint reduction plan, including the installation of energy efficient technologies (example: lighting, boilers, air conditioning), renewable energy sources, recycling, transportation and energy conservation behaviors (example: turning off unnecessary lights). Please submit a four to six page letter addressing the actions you would suggest, any issues or concerns regarding those actions, and any anticipated outcomes. You can include graphs, diagrams and
references only if they support your plan.

See me for help and to submit your entry if you decide to enter.
