Remake of Data Detectives: What on Earth is Happening? by Caitlin (Abby) McDevitt https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic First, look through each of the graphs and complete the yellow boxes to write down the independent variable (the x axis label) and the dependent variable (the y axis/graph line label), and then describe the trend shown by the graph. Then, look through the green hypotheses to match up each graph with the relevant hypothesis, and then state if the hypothesis is correct or incorrect and explain why using evidence from the graph to back up your opinion. en-us 2023-02-27 18:32:53 UTC 2023-02-27 22:11:50 UTC hello@padlet.com https://padlet.net/icons/png/1f9d0.png Graph 10 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842876 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842876 Graph 1 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842879 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842879 Graph 6 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842880 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842880 Graph 4 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842883 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842883 Graph 5 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842886 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842886 Graph 2 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842888 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842888 Graph 3 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842890 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842890 Graph 9 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842893 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842893 Graph 8 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842895 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842895 Do not scroll further down past this point! cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842896 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842896 Graph 7 cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842898 2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842898 Graph 1 Analysis cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842900

There is a high correlation between the number of cosmic rays (produced by the sun) and the temperature on earth.”
    Is the hypothesis true or false? False
    Explain your answer, using the graph as evidence: Although cosmic rays cause more than the average in the last 40 years, humans are not measured on the graph for the amount of temperature change so there is no way to tell whether the analysis is true or false. Also, as cosmic rays increases, the average global temperature decreases, thus not contributing to global warming.

It’s outside of our human control, so we should just enjoy life and not worry about it!"
    Is the hypothesis true or false? 
    False
    Explain your answer, using the graph as evidence: 
    According to Graph 9, there is no human activity on the graph, and thus we cannot conclude if humans do or do not contribute to global warming. Also, the changes in temperature and volcanic activity do not have the same trend, for the change in temperature increases over time, but the changes in volcanic activity fluctuates over time.

There are many natural sources of CO2, including plant and animal respiration and volcanic eruptions. The human causes are very small compared with the natural causes"
    Is the hypothesis true or false? 
    False

    According to graph 4, human causes have a higher contribution to climate change than natural causes.

Levels of CO2 have changed drastically throughout history based on many different factors - the current high levels of CO2 just follow these natural patterns.”
    Is the hypothesis true or false?
    This hypothesis is false.
    Explain your answer, using the graph as evidence:
    This statement is false because over the years, the CO2  levels have gone up and down, the highest point before present day was at 300 ppm 300,000 years ago. Now, the current level is close to 400 ppm, which has never happened before.

In fact, global warming has stopped and a cooling period is beginning.”
    Is the hypothesis true or false? False

From that line we can see that from 100 years ago, the temperature has increased significantly since that time.]]>     2023-02-27 18:32:53 UTC https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842926     Hypothesis E cmcdevitt26 https://padlet.com/cmcdevitt26/73vrgy0u9g9el0ic/wish/2496842928 "CO2 has nothing to do with global warming. Changes in CO2 do not match up with changes in temperature on earth."

    Is the hypothesis true or false? 
    False
    Explain your answer, using the graph as evidence: 
    Even though the prediction from the 70's is not perfectly accurate, the prediction in graph 5 was made in 2000, 30 years later, so that would mean that it could be more accurate than predictions made in the 70s.
