Junior Project
Junior Project
5% of your grade for the 4th Marking Period. Late projects are downgraded and receive a zero after five working days of lateness. Seniors and sophomores are exempt from the assignment.
Select two articles in one category from the list at the bottom of the page. Your articles should have contrasting ideas about the topic so that you can read about both sides of the issue. Once you have read the articles, you will write a 400 word response in which you take a position citing and/or refuting information from the articles. You must work alone, and your response will go into your ePortfolio. All submissions must be made on-line. The format for submission to Mr. Davison is to share the final document as a Google Drive Document (Formerly Google Docs) with bdavison40@gmail.com. This is my Google Drive link.
By Wednesday June 5 you will choose your two articles and inform your teacher of your choice of articles by creating a Google Drive Document with your full name, "Junior assignment" , and words that indicate your selection of topic in the title in the title linked to bdavison40@gmail.com.
By Friday June 8st you will submit an outline of your response on-line in the designated assignment. using the same shared google drive document.

Mouse Trap Vehicle Description for AP Physics
Project Description:
This is a performance based assessment, meaning you are graded largely on how your project performs not on the number of hours you worked on it. There are no partners and no teams. Students will use one Victor brand mouse trap as the energy source to drive a vehicle as far as possible down the hallway. They will get a maximum of three tries to produce their best distance and that distance will be the basis for their grade.
You may use any materials you wish as long as those materials do not add energy to the vehicle. For example rubber bands or springs or rockets that store elastic energy are forbidden. However, no kits are allowed. The use of a kit will result in a 30 point reduction in score. A 90 would become a 60.
Due Date: The first lab day after return from Winter Break.
Point value: 100 points for the final test output, with other point values assigned also. Example 5 points for drawing and materials list.

Numbered Heads Electrostatics Test Rview
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 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.
