Cutting Plants

Initial question (Why are we doing this experiment?): Gardeners or home decorators would like cut plants to last as long as possible. How can cut plants be kept fresh as long as possible?
Hypothesis (What we think will happen): Trimming the bottom of cut plants will keep them fresher longer.
Experiment description (what we did): Be sure to explain the experiment in detail so that others could read what you wrote and repeat the experiment.
Tools
Beaker, Water, Scissors, Ruler, Flask, Graduated Cylinder


• We went out to the garden and got 4 sunflowers that were approximately 10 inches long.
• With the two variable sunflowers, we cut ¼ of an inch off the stem daily and then placed them into a flask that was filled with 250ml of water.
• The two controlled sunflowers, we didn’t cut anything off of them, but we still placed them in a flask that was filled with 250ml of water.
• We got water from the same source everyday.


Data we gathered:
(charts and graphs)


Observations we made:
1. Explain what your data graphs show.
Our graph shows how much water we had to add to the flask everyday to make be 250ml.
First day – Started out with 250 ml. Then for the next 3 days we had to add however much to get it back to 250ml.
Second day- Control (added 50ml) Variable (added 20ml)
Third day- Control (added 14ml) Variable (added 13ml)
Fourth day- Control (added 13ml) Variable (added 15ml)

2. Explain what you observed each day including both control and variable.
On the first day of our experiment our plants were very healthy.
Second Day
Control- Healthy, Kind of bent over, stinky, pollen was falling off of it.
Variable- Healthy, Bent over, stinky, baby spider on it, white sticky stuff dripping off.

Third Day
Control- Bent flower healthier of the two, stinky, white sticky stuff dripping off.
Variable- Bent flower healthier of the two, stinky, white sticky stuff is gone.


Fourth Day

Control- Bent flower healthier of the two, stinky, white sticky stuff
Variable- VERY unhealthy, stinky, sticky, dry, petals are almost gone.

Conclusion:
1. Did the experiment support the hypothesis?
No, because we thought that the variable would last longer but in fact it did not the control plants did.
2. Were the results consistent with other experiments?
Yes , because everybody’s died right along with ours.
