Respond to the questions and/or prompts below and do your best. You've got this!

1

Some students notice that the force of a foot hitting the floor decreases when they increased the padding. Which of the following patterns might matches this data? There may be more than one - make the BEST choice.

1

A student lab group discovers that when students increase the amount of time they study, their grades increase too. Which of the following patterns might matches this data? There may be more than one - make the BEST choice.

1

Observation – Rachel asks the question, “How does the distance of my hand from the hinge affect the force needed to push open the door?” She then collects and graphs her data. The results are shown below.

Using the graph or the mathematical model, predict the force Rachel applied when the distance was 0.65 m.

1

What is the confidence in your prediction for the previous question? Explain. Use the confidence rubric to help you.

Observation – Rachel asks the question, “How does the distance of my hand from the hinge affect the force needed to push open the door?” She then collects and graphs her data. The results are shown below.

Use the mathematical model to calculate what force Rachel would need to apply for a distance of 2.0 m.

Zach notices that that the longer a line he draws with his marker, the more ink he has to use. He then asks the question, “How does the length of the line affect the amount of ink used?” Zach collects the following data about his marker.

Graph the data set using this desmos link, and insert a screenshot of your graph WITH THE MATHEMATICAL MODEL ON THE GRAPH PLEASE.

Zach notices that that the longer a line he draws with his marker, the more ink he has to use. He then asks the question, “How does the length of the line affect the amount of ink used?”

Looking at your graph above, which of the patterns from class best seems to describe your best fit line?

Zach notices that that the longer a line he draws with his marker, the more ink he has to use. He then asks the question, “How does the length of the line affect the amount of ink used?”

Looking at your graph and it's mathematical model above, type in your mathematical model in the space below.

Zach notices that that the longer a line he draws with his marker, the more ink he has to use. He then asks the question, “How does the length of the line affect the amount of ink used?”

Use the mathematical model from above to calculate the amount of ink used to make a 50 m line.

Jesus and Reyna decide to take data on their own pens and graph the results (shown below). Use CLAIM, EVIDENCE, REASONING structure to describe how Jesus’s pen (A) is different from Reyna’s pen (B). (Hint: think about what the "A" value is related to in this situation.)

The graph below shows data for a ball drop experiment. Identify the pattern.

1

The graph below shows data for a ball drop experiment. Use the graph or mathematical model to predict how far the ball will fall in 5 seconds.

In the next 2 questions you will describe the relevance of what we have been doing in class.  The following word bank may be helpful. (Note: you will not need to use all words from the word bank in each answer.)
