Some Like It Hot!

About 5 weeks ago laura and I decided on what we were going to do for science fair. Our amazing idea was What temperature out of boiling water at 9o'c warm water at 50'c room temperature at 30'c and ice cold at 10'c would keep a cut flower alive for the longest. Laura and I decided on this experiment because we thought it would be useful to know if there would be any way of preserving cut flower for longer. For the experiment we had 12 plastic cups 3 for temperature, we put 1/2 cup of water into each cup and then put 1 daffodil into each , we then changed the water every day at 10.20 am to heat it u or cool it down again. The results were that the boiling water killed the flowers within 4 days, the warm water killed the flowers within 5 days and so did the room temperature but the ice cold water kept the flowers almost perfect until the experiment was over. We found out that the reason the boiling water, warm and room temperature killed the flowers more quickly was because it excites the oxogen and lets it out while the waters boiling so there is not enough oxogen for the plant to survive. Laura and I think that we did quite well on our project and we really want to find out more about why there is not as much oxogen ing boiling water as cold. BUt overall Laura and I had a lot of fun doing our experiment and we can't wait until next time
