Transcript of Copy of Science fair competition !!!!!!!

The project is about an experimental design to determine if there’s a possibility to preserve the life of a cut flower using products such as carbonated beverage, Aspirin etc.. It is hypothesized that carbonated beverage will be the factor that preserves the flower best. Some of the materials that are being used are flowers and household products. Our method of conducting this experiment in a brief summary is cut the flowers at equal length, take vases or holders that can keep the flowers safe, also made sure that the conditions of the pants were all the same add chemicals and observe their behavior to the chemicals and record data. Over the course of the week we tested and the plants reacted differently to each chemical. In conclusion the hypothesis that was hypothesized was incorrect according to our experiment and the product that did end up preserving the life of the cut flower was aspirin.
Purpose
Materials
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
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.
In conclusion...
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?
Abstract
•5 Roses
•5 Carnations
•Carbonated Beverage
•Chlorine Bleach
•Lemon Juice
•White Vinegar
•Aspirin Water
•Vase
•Scissors
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.

Day : Monday-Tuesday

Carbonated Beverage (Carnations): The flower look fresh no signs of dying or anything bad, the petals don’t show any color change, and the stem is fine and green.
(Roses): The flower is still fresh no signs of anything bad and it’s in perfect and beautiful condition.

Chlorine bleach (Carnations): The flowers look fine, but the stem is starting to change color a little and the petals changed their color slightly to a yellow whitish color.
(Roses): The flower’s petal has changed color entirely and is some petals are starting to fall off and the petals have gotten really crispy.

Lemon juice (Carnations): The flowers show no change looks healthy and in perfect condition, just like the carbonated water.
(Roses): No sign of anything bad, petals look nice and healthy however the stem and leaves of the flower are changing slightly.

White Vinegar (Carnations): The flowers look nice and are holding there shape and its color are bright and no color change.
(Roses) The head of the flower is a little hanging but the flower is still looks healthy and shape is kind off weak but the color is good.

Aspirin water (Carnations): The flowers look perfectly healthy, roots and petals are nice, and shows no signs of withering.
(Roses) The flower did not change in any way it is pretty much healthy.

Carnations: The plant is healthy and look beautiful
Roses: The plant smells nice and is healthy.
Day : Wednesday-Thursday
Carbonated Beverage (Carnations): The plant looks healthy and it looks the same as it did a few days ago.
(Roses): The plant is still healthy however the leaves are changing colors.

Chlorine bleach (Carnations):The plant color is starting to change drastically and the stem looks bad as well.
(Roses):The plant looks pretty bad it doesn’t look as good and healthy as the other plants.

Lemon juice (Carnations):The plant looks the same as it did a few days ago the color is starting to change.
(Roses):The color of the plant changed to yellow and the stem looks weak, the plant is falling down.

White Vinegar (Carnations):The plant is healthy except for the stem it looks a little weak.
(Roses):The plant is starting to change color and the petals look different.

Aspirin water (Carnations):The plant is completely healthy and it looks the same as it looked when we started the experiment.
(Roses):The plant is green and the petals look pretty the whole plant is perfect.

Carnations: The plant is still healthy and is the same as it was a few days ago.
Roses: The plant is losing some of its leaves and petals.
Day : Friday- Saturday

Carbonated Beverage (Carnations):The plant is healthy but it looks like the petals are changing color.
(Roses):The plant leaves color change is more noticeable now.

Chlorine bleach (Carnations):The plant smells and it looks like like it wont last longer.
(Roses):The plant lost its green color completely the petals fell off and it also has a smell.

Lemon juice (Carnations):The plant looks OK but it is losing a lot of its petals.
(Roses):The plant is becoming a different color it doesn’t look healthy anymore.

White Vinegar (Carnations):The plant is starting to change change color but looks somewhat healthy.
(Roses):The plant's leaves are turning into the same color as the petals it isn't healthy anymore.

Aspirin water (Carnations):The plant is healthy and still has its green color left.
(Roses):The petals look good and the plant seems to be very healthy.

Carnations: The plant lost its color and the stem is falling down.
Roses: The plant is losing more petals but it still has its green color.
The purpose of this investigation is to determine if there is a way to extend a plant’s life after it has been cut by giving it different substances.
Hypothesis
Data continued ...
Sunday

Carbonated Beverage (Carnations): The plant is still healthy but the petals are changing color and the stem is getting weaker.(Roses):The plant looks very good and healthy, the leaves are the only change.

Chlorine Bleach (Carnations):The plant is looking really bad it looks weak the plant is falling down.(Roses):The plant is dying it seems like it has no more green color.

Lemon Juice (Carnations):The plant lost it petals and it seems like the color is changing yellowish.(Roses):The plant isn't healthy anymore and it lost its smell.

White Vinegar (Carnations):The plant is still somewhat healthy but its leaves are falling off(Roses):The plant lost its smell and the leaves,petals are yellow.

Water (Carnations):The plant is healthy and its leaves are still green(Roses):The plant is still fresh after a week it is perfectly healthy.

Carnations: The plant is getting its color back and it is still healthy.Roses: The plant is fresh and the petals smell nice as it did when we started the experiment.
Independent variable: The type of solution used.

Dependent variable: The way the pant looked after a week(observation).

Control Group: The carnations and roses that weren't given any of the different solution.
