2. Georgia’s bar is nearly halfway between the 0 and 50 mark for numbers of attacks. 20 is the most logical answer.

3. Tool What Does This Tool Do? MicroscopeUsed to observe objects that are too small to be seen by the human eye BarometerUsed to determine air pressure TelescopeUsed to observe objects outside of Earth’s atmosphere Wind VaneUsed to determine the direction of the wind PsychrometerUsed to measure relative air humidity These tools are used to measure some aspect of weather. Microscopes and telescopes are used to study other things.

7. If you look closely at the growth over the last couple decades, you would notice that the population has been growing by about 100,000 people (or a little more) every ten years. We could expect it to be more than 5,500,000 but not 8,500,000. about 5,100,000 about 2,850,000 about 3,800,000

8. I can make a conclusion about where the ash came from. B is a question. We can only infer C is correct; there is not enough information. D is an observation.

10. You live in Ohio and you need two days of fair weather so that you can spread fertilizer on your garden so that it does not wash away. 9. Looking at the weather maps above, on which day should you start fertilizing? A. Saturday, the 14th of the month B. Sunday, the 15th of the month C. Monday, the 16th of the month D. Thursday, the 19th of the month The weather maps show it might rain on Monday and that Tuesday should be clear. There is nothing in between Sunday’s front and Tuesday’s high pressure. You would not fertilize on Saturday or Sunday due to Sunday’s forecast. We can’t predict Thursday’s weather yet. Monday is the best choice.

12. There is only one battery so opposite polarity isn’t a possibility. We were told the switch has been closed so it must be made of plastic.

13. residential A B C 12. The researcher collects a water sample from locations B and C in the diagram and runs pH analyses on each sample. He finds that the pH in sample C is lower than the pH in sample B and concludes that the factory must be responsible for the low pH values in the lake. Give two reasons why the researcher’s conclusion may not be valid. Explain each reason using information from the diagram above. (4 points) C is downriver from B. Anything upstream from C could be causing the difference in pH. Reason One: The residential area could be releasing chemicals, cleaners, oils, and/or fuels into the river as runoff. Reason Two: The farm area could be releasing fertilizers and pesticides into the water. All of these things would flow toward C.

14. A controlled experiment should only test one variable at a time. The students want to see if different colors of sugar water affect the number of hummingbirds that come to their bird feeder so that is the ONLY thing that should be different in each experiment.

15. The seeds in the unsealed bag were also exposed to air while the others were not. It is necessary to start over to properly collect data.

16. 15. Which of the following statements could be a conclusion drawn from the investigation above? I can make a conclusion about the density of lemons and limes based on my observations. A is a question. B is the observation that allows me to conclude lemons are less dense than limes. I don’t have a thermometer to make sure D is correct.
