1.1 Analyzing Data Intro & Make Up

​1.1 Assessment Make Up

Carefully read each slide, write down any questions you have & do your best!​

First, we're going to review how to analyze a graph, then we'll try it out on the graphs from this topic.

​Reading Bar Graphs

Data is information that has been collected to represent real life situations, usually in number form but can be numerical or non-numerical information.

​​

Data can be analyzed in many different ways. In the next few slides you will analyze numerical data using a bar graph.

​

One way to display data is in a bar graph. A bar graph shows the relationship between different values of data. Each data value is represented by a column in the graph. The categories of different kinds of data are listed along the horizontal, or x, axis. The quantity or amount of data is listed along the vertical, or y, axis. 

​

Draw

Draw a circle around the X axis.

Draw

Draw a circle around the Y axis.

Multiple Choice

What is the graph measuring, according to the axes?

• X axis: students

  Y axis: Seventh graders

• X axis: Favorite Activity

  Y axis: Number of Students

• X axis: 7

  Y axis: Reading

• X axis: 0 - 10

  Y axis: Babysitting

Multiple Choice

Which activity is most favored by these 7th graders?

• Babysitting

• Reading

• Watching T.V.

• Hanging out with friends

Draw

Circle the Age Group that needs about 9 hours of sleep per day

How many years ago were you in preschool?

​How many years ago were you in elementary school?

Elementary School

​

How many years ago did you START middle school?

​

Middle School

​Think about the order of these 3 events to help you distinguish between events that happened FIRST and the events that happened MOST RECENTLY. ​

Draw

Circle the school a student would attend FIRST.

Multiple Choice

Which time period is MOST RECENT? (mya = Millions of Years Ago)

• 100 mya

• 200 mya

• 300 mya

• 400 mya

Multiple Choice

Which time period happened FIRST? (mya = Millions of Years Ago)

• 100 mya

• 200 mya

• 300 mya

• 400 mya

Multiple Choice

Choose the correct order of events in the Geologic Time Scale

• FIRST: Paleozoic

  NEXT: Mesozoic

  MOST RECENT: Cenozoic

• FIRST: Mesozoic

  NEXT: Cenozoic

  MOST RECENT: Paleozoic

• FIRST: Cenozoic

  NEXT: Mesozoic

  MOST RECENT: Paleozoic

Draw

Place an X next to the X axis label and a Y next to the Y axis label

Multiple Choice

According to the graph, when did the MOST RECENT mass extinction occur?

• 66 mya

• 251 mya

• 375 mya

• 444 mya

Multiple Choice

What percentage (%) of genera went extinct in the FIRST known mass extinction?

• 45%

• 50%

• 60%

• 80%

a straight line that runs from one side of a figure and passes through the center.

​

Diameter

Impact craters tend to be circular. This does not mean the object that created the crater was circular. Instead, the circular shape happens because there is typically a massive explosion upon impact. This explosion causes material to fly out in all directions.

​

Impact Event

Draw

Trace the vertical line that represents impact events of 100km, then circle the 2 largest impact events.

Multiple Choice

What two data sections have been added to the graph according to the X axes?

• Craters and diameters

• km and ma

• Extinction and Periods of Major

• Impact Events and Periods of Major Volcanic Eruptions

Multiple Select

According to the graph, which of the following time periods did Earth experience BOTH a ‘Major Volcanic Eruption’ and an ‘Impact Event’ from a crater with a diameter of at least 100km?

Select all answers that apply

• Between 50 and 100 million years ago (mya) AND

• Between 200 and 250 mya

• Between 350 and 400 mya

• Between 450 and 500 mya 

Multiple Choice

Complete the sentence to match a pattern in the graph.

Beginning at 500 mya, I notice as time goes on…

• Volcanic eruptions decrease

• Volcanic eruptions increase

• Volcanic eruptions ALWAYS happen after EVERY impact event

• Extinction Intensity increases

Multiple Choice

Students were asked to write a scientific argument based on data from the graph that explains what may have caused the mass extinction of the dinosaurs 66 million years ago.

Select the claim that CAN NOT be answered by the data.

• An asteroid collision most likely caused the extinction of the dinosaurs.

• Major volcanic eruptions most likely caused the extinction of the dinosaurs.

• Suffocation from smoke and lack of sunlight most likely caused the extinction of the dinosaurs

• A large impact event and a series of major volcanic eruptions most likely caused the extinction of the dinosaurs.

Multiple Choice

Students were asked to write a scientific argument based on data from the graph that explains what may have caused the mass extinction of the dinosaurs 66 million years ago.

Select the piece of evidence that CAN NOT be interpreted from the graph.

• They obviously didn't have enough food and water to survive because we've heard this story a thousand times.

• There is evidence of a crater over 150 km wide that happened at around the same time as the extinction intensity spiked to over 40% 66 mya.

• There is evidence of several major volcanic eruptions that happened around the same time as the extinction intensity spiked to over 40% 66 mya.

• There is evidence of both a large asteroid and volcanic eruptions that happened at around 66 mya.

Poll

How helpful was this slide deck in helping you understand how to analyze and interpret data for patterns in the fossil record that document extinction events?

• This didn't help me at all, I'm still really confused.

• It helped a little

• It helped me to understand this more than before.

• It helped a lot, I feel like I understand it much better now.
