After examining the data we determined we could not conclude whether or not there were differences in the impact of beet salt and road salt on germination. We decided the best next step was to do another experiment:

 Our experiment will be pretty much the same as last time, compare beet salt and road salt, but we will each put our own variable. Everyone will try to keep track of progress and keep more data like some sort of watering schedule and keeping track of water use. 

Variables everyone will use:

Independent variable: type of melting agent (beet salt vs road salt)

Dependent variable: rate of germination (how many germinate or not)

Set up controlled experimental variables that you could vary include: 

  • Paper towel or soil
  • Amount variable
  • Sunlight
  • Water temperature
  • Air temperature
  • Solid salt or diluted in water
