Ms. Lotzkar wants to find out if giant pumpkins grow faster than miniature pumpkins. In one pot she plants a giant pumpkin and in another identical pot she plants a miniature pumpkin. She waters both plants daily and places them in the same location. After one week, she adds a small scoop of fertilizer to the miniature pumpkin. After six weeks, she measures the plants using a meter stick and finds the plants to be the same exact size.
What is the IV?

DV: Growth
CV(s): The pots, waters daily, amount of water, growth conditions
100cm = _________ m
What is ... 1 m
What is the unit measurement for LENGTH?
What is ... Meters
e.g. kilometers, centimeters, millimeters
This step of the scientific method allows you to collect measurements and use statistical or graphical tools to process what happened during the experiment
What is the dependent variable?
What is ... a factor that is observed, counted, or measured to see how it responds.
Ms. Lotzkar decides to redo her penny lab experiment. She already collected data for heads and is about to collect data for tails. For trial 1, she got 25 drops. In trial 2, she got 30 drops. Lastly, in trial 3, she got 20 drops. Calculate the average for Miss. Lotzkar and her penny data.
What is ... 25 drops

What is the CV(s)?
What is ...
IV: The liquid (coffee, tea, water)
DV: Plant height (cm)/growth
CV(s): Pea Plant, amount of liquid, green house conditions, incubation/growth period (1 month), etc.
Marissa is an extremely curious sixth grader. During a snow day she looked out her window and saw a truck spreading something all over the road. After the truck went past Marissa's house, she went outside to play. She walked over to the edge of her driveway and observed salt all over the roadway, but not the sidewalks or her driveway. She also observed some of the snow and ice had melted off the roadway but not her driveway or sidewalks. She wondered if the ice and snow melting was due to the salt?
What is a testable question for Marissa?
What is the IV?
What is the DV?
What is a hypothesis Marissa can use?
What is ...
Question: What is the effect of salt on ice and snow with how quickly it melts?
IV: Amount of salt /salt
DV: Amount of ice and snow melted
Hypothesis: If I use salt on a snowy/icy path, then it will melt quickly because of salts chemical components breaking water ions down
