  3. How much water do seeds need in order to sprout?
  4. Do some kinds of seeds take longer to sprout than others?
  1. What is the I-Variable in this experiment? (what was different)
  2. The kind of cup
  3. The kind of seed
  4. How much water was used
  1. What were the constants that remained the same?
  2. The cups, the water, location and kind seeds
  3. The cups, the water and location of the cups in the sun
  1. The Scientific Method can be used ……
  2. At school in Science class
  3. At home to do a project like fix the lawnmower
  4. At work, when you begin working part-time, saving money
  5. All the above (a, b and c)
  1. (6.2E) For a science fair project, Jose did an investigation using bean seeds. He put 10 seeds with wet cotton in a jar (jar 1) and placed the jar in a closed cabinet in his room. He put 10 seeds with wet cotton in another jar (jar 2) and placed it in the dark, cold refrigerator. After a week, he checked the jars. Beans had sprouted in jar 1 from the cabinet. No beans had sprouted in jar 2 from the fridge.

Which conclusion can be drawn from the data in this investigation?

  1. Light affects the growth of bean seeds.
  2. Without soil, bean seeds will not sprout.
  3. Temperature affects the growth of bean seeds.
  4. Without moisture, bean seeds will not sprout.
  1. What was the I-Variable (independent variable)? (different)
  2. The seeds
  3. The location of the jars
  4. The time
  1. (6.4B) Which of the following activities would most likely require the equipment shown above?
  2. Catching fish in an aquarium
  3. Heating liquids
  4. Measuring outdoor temperatures
  5. Finding the mass of a rock sample
  6. It is ok to not wear your safety goggles or glasses if your eyes get itchy
  7. True
  8. False
  9. We always ‘reset’ the trays and materials exactly as we found them before we leave the room.
  10. True
  11. False
  12. Working ahead or touching lab materials is ok as long as you don’t break anything.
  13. True
  14. False
  15. If using hot plates, make sure the cords do not touch the hot surface.
  16. True
  17. False
  18. MSDS stands for Material Safety Data Sheet
  19. True
  20. False
