CP Physics Test Concepts for Light and Reflection

Light and Reflection Test Concepts

1. Table 1 applications pg 447 Ex. Which portion of the electromagnetic Spectrum is used in medical examination of bones?



2. Find Frequency given Wavelength using speed of Light, including use of prefixes like Mega and Giga, etc



3. Find Wavelength given Frequency using speed of light including prefixes



4. Commonality of EM spectrum in a vacuum regarding speed



5. Difference in colors of light regarding wavelength and frequency

Ex. What is different about red and blue light?



6. Distance v Light intensity relationship and applications
Ex How much light is available if we Triple the Distance from the source?



7. Finding angles of reflected rays from a plane mirror measured from horizontal and normal surfaces

8. Image and Object and Distance and Height for flat mirrors


9. Image and object Distance and radius of curvature for concave mirrors
Ex Know how to solve mirror and magnification equations

10. Focal length Radius of curvature relationship

11. Drawing ray diagrams of concave mirrors for cases 2-6 pg 460

12. Primary additive colors (Light)

13. Primary Subtractive Colors (Pigment)

14. Polarization of light

Tennis Ball Rocket Project Description

Tennis Ball Rocket Project

Project Description: Working in teams of two design and construct s a pressurized air based soda bottle rocket that is used to keep a tennis ball in the air for extended periods of time.


Point value: 100 pts Project category

Design constraints:

1. Only one pressurized 2 liter bottle allowed
2. No metal parts larger than 2” x 2” and or two grams total
3. No other sources of energy other than 80 psi air compressor
4. Rocket and or parachute must be free floating during the timing period
5. No kits
6. Rockets must have fins and nose cones


Grading

20 pts : Building day credits: everyone starts with 20pts total and deductions are received for lack of materials or failure to build during class time.

20 pts : two page write up of the physics principles involved in your design . Minimum of ten concepts documented

10 pts : completed launch of first prototype before deadline May 20

10 pts : completed launch of second prototype before deadline May 27 Must be significantly different than prototype 1

The following Updated Rubric is an attempt to better delineate the point values in each performance grade category. Overall, It makes it easier to be in the "A" range and raises the majority of student scores.

Updated Rocket Rubric Mr. Davison

A+ = 30 seconds and up 40 pts

A = 24-29 sec 38 pts

A- = 21-23 sec 36 pts

B+ = 18-20 sec 35 pts

B = 15-17 sec 34 pts

B- = 12-14 sec 32 pts

C+ = 11 31 pts

C = 10 30 pts

C- 8-9 28 pts

D+ = 7 27 pts

D= 6 26 pts

F = Less than 6 but launched 20 pts

F = No launch 0 pts

Numbered Heads Review for Heat (CP Physics)

Numbered Heads Activity Heat Review

Directions:

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 and figure out what question the teacher will ask. Time is limited; so don’t waste it!

5. Once you understand the concepts make sure each group members also 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?”

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.

Concepts:

1. Molecular reason for temperature increase





2. Internal energy definition and understanding of what is happening






3. Kinetic energy of molecules temperature relationship






4. General temperature volume relationship for liquids and known exceptions (water 0 degress C to 2 degrees C)






5. Final Temperature calculation when mixing equal masses of same substance with known temperature of each






6. Familiarity with widely used Temperature scales temperature



7. Temperature increases in Celsius changed into Farenheit increases






8. Common point between C and F scales and MP BP of water for each





9. Heat definition






10. Three heat transfer methods







11. how house insulation works






12. PE KE U relationship





13. Find delta T if Q, M, C are known





14. Description of Temperature during a phase change vs during a phase






15. Interpret heating of water diagram all three phases including calculating M, C, Q or delta T





16. Calculate C to F C to K




17. Calorimetry calculation between hot metal and water Solve for C of metal



18 Calorimetry calculation between hot metal and water Solve for T final of metal and water
