Numbered Heads Chap 3 Review

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.

Chap 3 Concepts for the test.

1.  Vx and Vy  of an object at rest and at the top of an ark and shot horizontally

2.  memorized equations for motion ---One for X and four for Y

3.  vector v scalar

4.  how to add or subtract perpendicular vector components

5.  sliding vectors over to apply tip to tail rule for vectors 

6.  adding and subtracting vectors that are parallel.  (ie in a line)

7.  Find resultant displacement or velocity involving N,S, E, W given resultant (Expressing the angle from a reference line)

8.Find Horizontal displacement given resultant velocity and angle 

9.  Relative velocity of an object dropped straight down from the perspective of an observer moving with the object

10. Given a bunch of vectors, state the number of vectors that have only Y components or X components

11.  projectile motion problems

12.  shape of an object in projectile motion

13.  interpreting D-T graphs for projectile motion

14.  Given the resultant and a third side, find the perpendicular component of the vector system

15.  addition of nonperpendicular vectors by adding x and y components to make a perpendicular system

16.  projectile problem given resultant velocity,  angle of throw and time in the air, find the height.

Stomp Rocket Lab

This is the most excellent link to the stomp rocket lab.

What is required of you is the following by next lab period:

I.  google doc with names of each member in the title, shared with teacher = bdavison40@gmail.com

II.  Clearly stated purpose

III.  Summary of Procedure  (7-10 steps)

IV.  Data table of your results

V picture showing setup and team members

VI.   All analysis questions answered by each member in a different color.

Projectile Motion Lab

Here is the darn link to the Vernier Projectile Motion Lab.    Your lab report should be in Google Docs form and include:

I.  Purpose

II.  Preliminary questions  (each member dif. color)

II.  Summarized procedure (8-10 steps)

III  Data in table form

IV.  Picture of setup

V.  Analysis questions answered by each group member.



This is due by next lab period.
