ASK A QUESTION
During this lab we…watered plant seeds, took their weight, and saw if they
grew and how tall if they did.
What we wanted to find out…why didn’t our plant grow?
CONTROL VS. VARIABLE
STATE YOUR HYPOTHESIS
In this slide you are to write whether your group was a control group or an
experimental group. Control a control group waters a plant with unpolluted
water.
State your hypothesis the plant will not grow. My hypothesis was that the plant
will grow.

DATA INTERPRETATION
What happened during your experiment? My plant grew because we had
unpolluted water.
Think about: What could have affected your data (amount/type of water,
sunlight, seed, etc.). What could of effected our plant is not enough water, or
too much.
Explain your graph-Give a three to five sentence explanation of your data.
Over a period of time my plant got heavier from water, then lighter from
getting dried out.
STATE YOUR CONCLUSION
My hypothesis that stated…was (correct/incorrect). Why do
you think this happened? Correct. I said our plant our plant
would grow because we had unpolluted water.
What was something you learned from this experiment?
Something I learned from this experiment was that polluted
water will kill plants.
How would you alter this experiment for future use? I will use
unpolluted water for my plants.
