Can plants SURVIVE on orange juice?
The Aim:

My aim was to find out if a flower could survive on orange juice rather than tap water.
Change Variable:

My changed variable is the type of liquid used in the experiment.
Measured Variable:

The amount of liquid used in the experiment (160ML).
Fixed Variables:

The flowers, the amount of liquid used, the cups used and where you keep the flowers.
Hypothesis:

I predict both flowers will survive and I think this because both flowers are in liquids that are naturally occurring.
Bad Quality :(
Materials:

2 of the same flowers
2 rubber bands
2 pieces of cling wrap
Orange juice (80ML)
Tap water (80ML)
2 Styrofoam cups
Method:

Buy 2 of the same flowers, cut them in case they are too big for the cup and make them the same size. Pour 80ML of tap water in 1 cup then 80ML of orange juice in the other. Put 1 cling wrap on both cups, then poke the flowers through the cling wrap. Then make sure both cups are in the same place or the test won't be fair.
Observations:
Day 1 observations, nothing has happened to the flowers yet.
Day 2 pictures N/A, but flower in orange juice starts to wilt and decay.
Day 3 pictures N/A, flower put in orange juice continuing to wilt and decay. Not long till it dies and orange juice getting moldy.

Day 4 pictures N/A, flower in orange juice simply dead experiment over. Orange juice was also a lot more moldy from day 3.
Results:

My hypothesis was wrong because the flower in the orange juice died and the flower in the tap water survived. The conclusion is that you can't keep a flower alive in orange juice but I might try this experiment again and change the orange juice and tap water every day to keep each liquid cleaner. I should also use freshly squeezed orange juice rather than orange juice from a box.
