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.

Electrostatics Test Review Concepts

1.  Be able to write out the Coulomb's Law Formula, E field Formulas (there are two)

2.  Explain how to get an induced charge and relate it to lightning 

3.  Find the size and direction of a force given two charges, a distance and K

4.  Know your prefixes, nano, centi, milli, micro, kilo

5.  Find the size and direction of the resultant force when three charges form two forces that are perpendicular

6.  Find the size and direction of the resultant force when three charges form two forces that are nonperpendicular

7. Calculate the resulting E field on a point charge when the vectors are linear.

8  Calculate the resulting E field on a point charge when the vectors are perpendicular

9.  Calculate the resulting E field on a point charge when the vectors are  non perpendicular
