**Teacher Comment: You have created a really good reliable method here Olivia which means that you considered your variables etc. Next year see if you can come up with an eye catching title that draws the readers to it. Great to see that you have included the an explanation that discusses your results. You have presented your science fair well Olivia you should be proud of yourself.**

__**Intro:**__ I chose this experiment because flowers never seem to last that long in my house and I wondered why and it got me wondering what if I put the same type of flower in different liquids and see what flower lasted the longest.

__**Aim:**__ My aim is to find out what liquid helps flower’s last the longest.

__**Hypothesis:**__ I think that bleach and water will make the flower’s last longest because my mum always says that bleach and water together will make cut flower’s last longer than water by itself. I think that salt and water will make the cut flower’s die because flower’s and salt don’t sound right together.

__**Equipment:**__ 5 cups(glass) 5 cut flowers(Carnations) porridge(just the oats) bleach water sugar sprite salt

__**Method:**__ 1.Put one flower in 5 cups then in the separate cups put the porridge and water, water, bleach and water, salt and water, Sprit, sugar and water make sure you only use one cup of water for every experiment apart from the sprite. 2.Wait 48 hours and see how they are doing then wait another 48 hours etc etc

__**Results:**__ Sprite lasted 20 days and made the flowers bloom way more than the rest and the stalk stayed straight. Bleach and water together took the colour out of the flowers and the stalk was bent and took days 11 salt took days water by itself took 12 days and the stalk was bent sugar took 14 days and the stalk was bent porridge 9 days and the stalk was bent. Water took 13 days and the stalk was bent.

__**Conclusion:**__ My hypothesis was wrong because sprite took the longest of 20 days and made the flowers bloom lots more than the rest of the flowers and its stalk stayed straight all the rest were bent over the glass and didn’t look the best the fasted flower to die was the one in the porridge it lasted 9 days. salt and water and sugar and water grew mold on the stalks. I have learned that porridge with water dies the fasted out of these liquids and I would recommend you use non-diet sprite for your flowers or else it won’t work. Cut flower require carbohydrates(or sugars) stored in the leafs or stalks but when harvested young these flowers may not have enough

__Why do you get the Hiccups__ Lots of people get the, Hiccups are caused by irritation to the phrenic or vagus nerves, related to breathing and the nerves of the esophagus(connects the stomach to the throat) and stomach. These are associated with the diaphragm (breathing muscles) and cause spasmodic inhalations known as hiccups. The diaphragm suddenly pulls down, causing the epiglottis to close. That is why we get the hiccups and now you also know what they are.

 __Aim__ To find out substance A, B, C, D and E

__Hypothesis:__ We think that A is cornflour B is salt C baking soda D is cream of tar tar E icing sugar

__Results__ A-Cornflour B-Salt C-Baking soda D-Icing sugar E-Cream of tar tar
