  1. List the general steps of the scientific method:
  1. Read the following experiment and identify the following parts of the experiment.

Maverick wants to find out whether or not Miracle Grow really makes plants grow faster. He takes two identical pots, puts ½ cup of dirt into each one, and puts 3 pea plant seeds into each one. He waters the plants the same amount at the same time each day. The only difference is that one plant is watered with regular water, while the other is watered with water that has Miracle Grow in it.

  1. Identify the control group.
  1. Identify the independent variable.
  1. Identify the dependent variable.
  1. How could the experiment be improved?
  1. Read the following experiment and identify the following parts of the experiment.

Bailey wants to find out which frozen solid melts the fastest: soda, ice, or orange juice. She pours each of the three liquids into the empty cubes of an ice tray, and then places the ice tray in the freezer over night. The next day, she pulls the ice tray out and sets each cube on its own plate. She then waits and watches for them to melt. When the last part of the frozen liquid melts, she records the time.

  1. Identify the independent variable.
