Remake of Data Detectives: What on Earth is Happening? by Anne Ginna https://padlet.com/aginna232/t2ac362l54zwa5sa 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 2021-03-08 22:02:33 UTC 2025-09-25 16:12:17 UTC hello@padlet.com https://padlet.net/icons/png/1f9d0.png Graph 10 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682074 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682074 Graph 1 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682076 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682076 Graph 6 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682077 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682077 Graph 4 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682080 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682080 Graph 5 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682083 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682083 Graph 2 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682085 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682085 Graph 3 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682086 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682086 Graph 9 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682088 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682088 Graph 8 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682089 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682089 Do not scroll further down past this point! aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682090 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682090 Graph 7 aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682093 2021-03-08 22:02:33 UTC https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682093 Graph 1 Analysis aginna232 https://padlet.com/aginna232/t2ac362l54zwa5sa/wish/1284682094

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: The temperature change is caused by both Cosmic Rays and humans, because on the graph both Cosmic Ray and Global temp are increasing meaning they are both cause temperature changing.

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: We see that the change in temperature does not line up with the changes in volcanic activity, hence global warming is not caused by volcanic activity.
