Patterns Physics
This is our third quiz of the year and it will cover the science inquiry process we used to make a data-based prediction for how many pennies can can fit into a 56 cm circle.

This week there will only be a multiple choice and essay in GoFormative.

There is a time limit on this quiz, which is due at the end of the class period, but it will likely take you much less time. When done, please begin work on collecting data for our next experiment.

Take a deep breadth, take your time to read each question, and pick the best answer- or write what you think. When done, I will have you work in teams on a new experiment where we will look to discover a new pattern.

I wish you the best!
Mr. Scannell

When introducing an experiment and before we have collected any data, you got a chance to think about the real life experience and make a wild guess prediction. Then, we have engaged in science inquiry using the process below.



Providing evidence from this class, explain why in science we prefer a data-informed decision over a wild-guess: To receive full credit for this question, you should provide at least 2 pieces of evidence from our experiments.

Optional (this question is not scored as part of your grade): Based on your thoughts about the quiz, please provide any feedback to Mr. S. about the quiz and how you are doing. We are just finishing week 5 and I want to do all I can to help you be successful. Thank you.

Looking at the graph below, which of the following represents an actual data point on the graph (x,y).


(15, 40)
(10, 30)
(15, 50)
(0, 5)
Looking at the graph below, which of the following are similarties in both lines?


The lines are the same color
The lines have the same equation
The lines have the same steepness
The lines both start at (0,0)
Looking at the graph below, which of the following are differences between both lines?


The lines are both positive
The lines have the same A value
The lines have the same steepness
The A values are different
For the graph below, what is the A value for the steepest line?


0.10
0.22
1.0
D
D^2
For the graph below, what is the A value for the largest coin?


0.10
0.22
1.0
D
D^2
Something special about the A values for these graphs is...
The A values change as the diameter of the circles gets bigger.
The A values are the same for all coins
The A values for each coin are constant, they do not change.
None of these
Which of the following is a true statement?
The bigger the A value, the larger the coin
The bigger the A value, the flatter the line
The bigger the A value, the smaller the number in the equation (ie. the coeffiecient)
The bigger the A value the steeper the graph and the smaller the size of the coin
The A values shows up in the graph as the
color of the line
the number of words in the equation
the steepness of the graph
A student in Physical Science asked, "Hey what would the A-value be for a dime?" Another student said, oh, that should be easy to predict since a dime is a little smaller than a penny. Based on our experiments, I would expect the A-value for a dime to be _____."
A=0.22, because it should be the same A value as the penny
A< 0.22, because the dime is smaller than a penny, the A value should be less than that of a penny.
A> 0.22, becuase the dime is smaller than a penny, the A value is larger than that of a penny
What does the A-value have to do with it? The A value is constant for all types of coins.
The graph below shows the number of marbles that will fit within a metal ring (like the lid to a jar). Based on the graph, how many marbles would be found in a ring with a diameter of 8 cm

About 20 marbles
About 40 marbles
About 60 marbles
About 100 marbles
Using the graph (# marbles vs. diameter) above, students made a data-informed decision for a ring that was 8 cm in diameter. However, they were uncertain about their confidence in their prediction. Which of the following confidence and reasoning is most accurate.


My confidence in predicting for 8 cm is high because the best-fit line goes through the center of most of the data points and the prediction is within our data range.
My confidence in predicting for 8 cm is medium-high because the best-fit line goes through most of the data points and the prediction is outside our data range.
My confidence in predicting for 8 cm is medium-high because the best-fit line is near the edges of many of the data points and the prediction is within our data range.
My confidence in predicting for 8 cm is medium because the best-fit line is near the edges of many of the data points and the prediction is near the data range.
My confidence in predicting for 8 cm is medium because the best-fit line is near the center of most of the data points and the prediction is far from the data range.
Two groups collected the following data using metal ball bearings and glass marbles.




What is the A value for the graph showing the ball bearings? ( look at the picture in the graph to see a scale drawing)
0
0.22
2.2
0.3
Two groups collected the following data using metal ball bearings and glass marbles.




Using the graph above and the equations: How many ball bearings do you predict would fit in a 10 cm diameter circle.
2.2
30
220

We found that in a quadratic pattern, the shape of the graph is a ...
horizontal line (flat line)
a straight line with a positive slope.
a curved line that curves upward
none of these
We found that for the quadratic pattern, when the X variable doubles, the Y variable _____________?


stays the same
doubles
triples
quadruples
halves
None of these
What you think? This Quiz was... (this question is not scored as part of your grade)
too hard
too easy
it was reasonable and related well to what we did in class
