Transcript of Copy of Science fair competition !!!!!!!
1.First we will take all the flowers and cut them equally in length and cut of the stem and completely smooth the stem of each flower.
2.We will take vases enough for our experiment and fill each with the substance we are measuring to see which substance helps live the flower longer.
3.We will have to make sure all the plants are kept in the same amount of temperature; they are given the same amount of substance and same amount of sunlight.
4.After placing the flowers in the substance we will then observe the flowers and see for any physical change that might occur in the plants (color, dryness, withering, dying etc…) we will take pictures after every 12 hours to record a change.
Data Continued ...
Data Continued ...
It is Hypothesized that Carbonated Beverage will best prolong the life of a cut flower, because Carbonated Beverages contain carbon dioxide which plant need to live.
The hypothesis was incorrect we thought carbonated soda would work the best however it was aspirin water the plant had its green leaves and was very healthy. Chlorine bleach was the worst among the solutions the plant looked very bad after a week and the plant looked like it would only last a few more days. Aspirin water was very healthy there were no big changes that happened to the plant it was very healthy. I thought it was not fun but actually it was fun, and I have never experimented like this so I thought it was a good experience.
Which substance best prolongs the life of a cut flower?
5.We will continue this experiment until each flower is completely dead or the flowers that last the longest living or is showing no signs of dying.
6.Lastly we record the data into a table, and see which substance made the life longer to the cut flowers.
