Here is the link to the Bonobos Video.  Watch in class.  Finish at home and be prepared to discuss for THursday.

AP Physics Solar Water Distillation Project

Description:  Students will design and construct a solar thermal powered still.

1.   The device will change dirty salty water into clean pure drinkable water of low conductivity as measured by a conductivity probe.

2.    Grading will be based upon a 24 hour test period of 90% sun starting June 10th in a secure area on campus.  In the event of clouding a second test will be performed June 11th, or when sun is available.

3.  The total area of collector may not exceed 0.36 square meters.

4.  80% of the materials by weight must be  post consumer materials  such as used food containers, cardboard, worn tires,   construction debris, etc.

5.  Value:  This project is valued at 100 points.

6.  The test will be done on grass in the courtyard.

7.  Your project is required to have wind protection for winds up to 30 miles per hour.  There is  10 point deduction for designs without wind protection.  If ballast is your plan you are required to use at least 10 pounds.

8.  The reliance on tape to remove your clean water  will result in a 10 point deduction.  This is an inferior material for a project that generates steam.  Do not tape your glazing to your project body.

9.  A deduction of 10 points will result if your project requires more than 5 minutes to add dirty water, secure the glazing and stake down for wind protection.

10.  Grading will be based upon the production of clean water in mls.

300 ml =  A

200 ml = B

100 ml = C

50 ml = D

Less than 50 ml = F

Suggested design elements:

1.  Research the best orientation for capturing maximum sun in our latitude

2.  Do not allow vaporized clean water to escape from your project

3.  Keeping mass low will allow for quick temperature increases.

4.  Selective insulation can prevent heat loss through radiation back into the environment

5.  Some glazing will prevent light transmission.  This is to be avoided

6.  To maximize condensation your condensation surface must be cooler than the vapor inside your project

7.  Here is a link to a small still made from some recycled components

Physics Mouse Trap Boat Project

Description:  Construct a mousetrap powered boat that fits in the classroom channel.  This is a speed competition.  Your boat will receive a grade based on how quickly it reaches the end of the channel.  Your boat may not exceed 16 inches when starting.  You may use any materials as long as they do not add energy to the competition.

You may work with a single partner or you may work alone.

Point value:  100 points

Final Due date:  May 27 for AP and  May 30 for CP Physics

Starting  materials Due 15 for AP and May 19 for CP

The A + will be 3.5 seconds.

The rest of the rubric will be determined later but boats that do not reach the finish line will not pass.

CP Physics Numbered Heads Review Chap 16 and !7

Numbered Heads Instructions

1. Form into the designated groups

2. Take out one full sheet of paper per group and list the name of the group at the top. Then list the names of the group members and place numbers next to each name (1, 2, 3…..If four members then write 4 also). It doesn’t matter who gets what number.

3. Hand the paper to the instructor. It will be used for assessment and graded.

4. Begin reviewing/ learning the listed concepts. Make up sample questions related to the concept. Try to imagine what question the teacher will ask. Time is limited; so don’t waste it!

5. Once you understand the concepts yourself locate the group members who do not understand  by assessing them. Do not ask yes or no assessment questions.

Good Assessment. “Sam, could you show me how to do number three on the list?”

Poor Assessment. “Do you guys all know it?”

Now teach them how to answer the questions you have formulated.  

6. When the instructor calls a number randomly (ex. = 3) the three will go to a designated area alone and respond to a similar question. Make sure they have something to write with and a calculator. After they leave begin studying the next set of concepts for the next round.

7. After a short amount of time the person will then return to the group and their answer will be graded by the teacher and given to the entire group as a communal score.

8. The returning group member may be called again so they should receive extra instruction to help get caught up.

9. The scores are added at the end to determine winners. The top three groups receive extra points on the test.

List of Concepts"

1.  Considering three charges in a line with known distances, solve for the  E field strength of a fourth test charge at a known location.

2.  Considering three charges in a line with known distances solve for the resultant force on one of the charges.

3.  Considering three charges  90 degrees apart solve for the resultant force on the charge at the 90 degree vertex.  This is perpendicular vector addition.

4.   Considering three charges  90 degrees apart solve for the resultant force on the charge not at the 90 degree vertex.  This is non perpendicular vector addition.

5.  Be able to draws E fields based on single charges or combinations of charges

6.  Solve for PE given q E D or any combination

7.  Solve for Change in potential  given Change in Pe  and charge  or any combination

8.  Solve for capacitance given charge and potential dif or any combination

9.   Solve for capacitance of a parallel plate capacitor given area and separation distance.  Know the value of Epsilon zero

10.

Know the Electric potential energy stored in a capacitor given charge and potential difference

11.  Know Ohm's Law I = V/R  and any variation

12.  Know that Current is charge divided by time period and be able to solve  for one of the variables

13.  Know that power is Current multiplied by Potential difference and any variation of this formula
