In light of the fact that this year project grades are based on two separate test, the new grade scale is as follows:
D = 10-12.99 meters
D+ = 13-14.99 meters
C- = 15-16.99 meters
C = 17-18.99 meters
C+ = 19-20.99 meters
B- = 21- 23.99meters
B= 24- 27.99 meters
B+ = 28-29.99 meters
A- = 30 -32.99meters
A = 33-34.99 meters
A+ beyond 35 meters

Chap 7 Numbered Heads Review Instructions and Concepts
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.

Physics Link to Newton's Second Law Experiment
Directions: Follow the link to the second law computer experiment and then collect data on time and acceleration for 10 totally different cart weights and ten totally different hanging mass weights.
When you are done you should answer the following analysis questions:
1. What effect does adding mass to the cart have on acceleration?
2. What effect does lowering mass to the cart have on acceleration?
3. What effect does increasing mass on the hanging weight have on acceleration?
4. What causes the downward force on the hanging mass?
5. What is the formula that links force, mass and acceleration? and what is it called?
6. If a 1 kg falling mass pulls a 1 kg cart what is the acceleration?
7. How does this lab relate to the way your car would accelerate when pulling a trailer or loaded with passengers?
8. What would the physics justification be for limiting the number of passengers for new drivers?
