  1. 2. The scientific study of animals and their behavior. She majored in zoology because of her lifelong fascination with wildlife.
  2. 6. A statement about what will happen or be observed in the future. Based on the hypothesis, the prediction was that the plant would grow taller with more sunlight.
  3. 8. Any factor, trait, or condition that can exist in differing amounts or types. The temperature of the water is a key variable in this experiment.
  4. 10. The variable in an experiment that is changed or manipulated by the researcher. The independent variable in this experiment is the amount of fertilizer used.
  5. 11. Relating to, or based on, an experiment. The experimental group was the one that received the new treatment.
  6. 13. A proposed explanation for a phenomenon, which is a starting point for further investigation. A good hypothesis should be testable and falsifiable.
  7. 16. The variable in an experiment that is measured or observed to see if it is affected by the independent variable. The dependent variable is the plant's growth, which we will measure daily.
  8. 17. The scientific study of matter, energy, and the fundamental forces of nature. Isaac Newton's work in physics laid the foundation for classical mechanics.

  1. 1. The scientific study of the atmosphere and weather. A meteorology expert predicted a high chance of thunderstorms later in the day.
  2. 3. Relating to, measuring, or measured by the quality of something rather than its quantity. The qualitative observations described the texture and color of the rock sample.
  3. 4. Dismissed as untrue or invalid. The hypothesis was rejected because the data did not support it.
  4. 5. Considered to be true, valid, or appropriate. The hypothesis was accepted after repeated experiments showed consistent results.
  5. 7. Relating to, measuring, or measured by the quantity of something rather than its quality. The quantitative data showed that the population of butterflies had decreased by 20%.
  6. 9. The part of an experiment that is used as a baseline for comparison. The control group received a placebo instead of the experimental drug.
  7. 12. A conclusion reached on the basis of evidence and reasoning. The detective's inference was that the suspect had fled the country.
  8. 14. The scientific study of the physical structure and substance of the Earth. The geologist studied the rock formations to learn about the area's history.
  9. 15. The scientific study of the properties and behavior of matter. We conducted an experiment in chemistry class to identify the unknown substance.
