October 1 (Monday) Review
Einstein Board today:
1. Handout review sheet for unit 1; the test tomorrow.
2. Students follow the instructions on the review sheet by working in groups of two and then comparing their answers with another group of two before grading them from the KEY TO THE REVIEW SHEET.
Teacher is handing back papers and letting students know what outstanding assignments need to be turned in.
3. Students grade the Practice Problem Sheet from the Practice Problem Key by changing the ones they had wrong before studying the sheet for tomorrows test. Students turn in the sheet in tomorrow before the test if they haven't already done so last Friday when the sheet was due. Here are some of the practice problem sheet problems done in class duri
3. Show smile2340.com Homecoming Video collection. Have class chose one to watch from each event.
4. Lights off learning the last 13 minutes of the class. (During lights off learning, I'll explain:
a). No erasing on the scan tron multiple choice. Instead if you wish to change a already marked C to an A just write A in front of the number of the problem you are on.
example: A 23). A B X C D E Whatever letter is written in front takes priority over bubbled.
b). No music during test. You may where headphones and listen to your own music if it does not bother anyone around you.
c). You will need your own #2 pencil and calculator during test.
d). Bring something else to do because you will finish early. No talking until everyone is done with the test.
e). LAW OF FALLING BODIES is that any object will fall at the same acceleration in a vacuum such that the distance fallen is directly related to the time interval squared. Thus during 1 interval of time and object will fall 1 unit, during 2 intervals of time 4 units, during 3 intervals 9 units, during 4 intervals of time 16 units of distance and so on... Thus if you tied objects on a string they would end up a consecutive odd numbers apart meaning the first object would be 1 unit from the end of the string but the 2nd object 3 units from the second (or 4 from the end of the string) and the 3rd object 5 units from the 2nd (or 9 units from the end) and the 4th object would be tied 7 units from the 3rd (or 16 units from the end since 16-9 = 7) and so on
f). If an object is NOT following in a vacuum it will still follow the law of falling bodies until it reaches terminal velocity at which point it stops accelerating thus stays a constant speed at that point. The main two factors that determine when an object will reach terminal velocity is mass and Area. Terminal Velocity is directly related to the square root of m/A meaning if the mass is 9 times as much the Terminal Velocity will be 3 times as high but if the area is 16 times as much the Terminal Velocity will be 1/4 as much. If you made both the mass 25 times as much and the Area 100 times as much the terminal velocity would be 5/10 or 1/2 as much.
g). Graphs are set up so that if one figures out the slope at any point on the graph the slope has meaning. Thus since slope is rise over run; if the rise (y axis of the graph) is distance and the run (x axis of the graph) is time the slope of a distance/time graph would give you the objects instantaneous speed. The slope of a speed/time graph would be m/s/s or acceleration. The slope of a volume/mass graph would give you the density of the object and so forth. Side note: Note if the x axis is time and time cannot go backwards you are sure it is a function.
h). Look through all your sheets and make sure you understand them especially the practice problem sheet.
i). On the practice problem sheet if you tackle a problem by listing all the givens, hidden givens like initial velocity is zero and acceleration equals gravity or 9.8 m/s/s and figure out what letter stands for what they want you to solve for....then you just need to fit the given variables to a formula that contains those variables so you have one equation and one unknown. Note Practice Problem Key.
