  1. SOL REVIEW SCIENTIFIC INVESTIGATION

  2. What variable is changed by the experimenter? Hint: remember MIX

  3. Answer= Independent VariableM stands for manipulatedI stands for IndependentX stands for X axis

  4. What variable responds to the changes in the independent variable? Hint: remember DRY

  5. Answer= Dependent VariableD stands for dependentR stands for respondingY stands for Y axis

  6. What do we call variables that we keep the same? We don’t change these variables.

  7. Answer= Constants

  8. This is the standard of comparison. We compare our results to this group.

  9. Answer= Control

  10. A testable idea or explanation that leads to scientific investigation. Also, phrased with an, “If then statement.” If I do this then this will happen.

  11. Answer= Hypothesis

  12. A system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation.

  13. Answer= Theory

  14. A general statement that describes how the natural world behaves under certain conditions and for which no exceptions have been found.

  15. Answer= Law

  16. Process of using the senses of sight, touch, taste, hearing, and smell to gather information about the world.

  17. Answer= Observation

  18. An interpretation or explanation of an observation.

  19. Answer= Inference

  20. What is the metric unit for these measurements? -Length= -Volume= -Mass= -Temperature=

  21. Answer= What is the metric unit for these measurements? -Length=centimeter (cm) and meter (m) -Volume= liter (l) milliliter (ml) -Mass= grams (g) -Temperature= Kelvin (K)

  22. What is this tool used to measure?

  23. What is this tool used to measure? Answer= Length

  24. What is this tool used to measure?

  25. What is this tool used to measure? Answer= Volume

  26. What is this tool used to measure?

  27. What is this tool used to measure? Answer= Mass

  28. What is this tool used to measure?

  29. What is this tool used to measure? Answer= Temperature

  30. A measure of the amount of matter that occupies a particular space is called __________.

  31. A measure of the amount of matter that occupies a particular space is called DENSITY

  32. What is the formula for density? Remember……we love density

  33. A block of aluminum has a volume of 17.0 ml and a mass of 45.9 g. What is its density?

  34. A block of aluminum has a volume of 17.0 ml and a mass of 45.9 g. What is its density? Answer= D= M/V D= 45.9 g/ 17.0 ml D= 2.7 g / ml

  35. Using the graph above, describe how temperature changes as the altitude in the atmosphere increases.

  36. Using the graph above, describe how temperature changes as the altitude in the atmosphere increases. Atmospheric temperature changes from layer to layer. Gases expand when they are heated and contract when they are cooled. Hot air is less dense than cool air. Increasing air temperature decreases atmospheric pressure. Decreasing air temperature increases atmospheric pressure.
