** 2. Explain how to set up the experiment: **
> ** -type of flower -height of flower -width of flower -how old the flower is -quality of the flower (dead/alive) -where the flower was found -where the cut was made on the flower -how long it sat out in the air after being cut -how tall the vase is -how wide the vase is -how much water is in the vase -where you got the water -quality of the water -brand of asprin -how much asprin is in the water -where the experiment is done -the temperature of water -what is in the asprin -how large the pill is -how many vitamins and minerals are in the asprin -shape of the flower -where you got the asprin -when you cut the flower -what type of scissors were used to cut -color of flower -if the flower has bloomed -how much water you add per day -how much asprin you add per day -how many flowers are in one vase -how tall the flowers stem i **** s -when you put the asprin in the vase -stems were cut in the same place on flower ** > > == ==

==** A scientist wonders if flowers kept in water with asprin will last longer than flowers kept in regular water. He went outside and picked 100 flowers from the same spot in his yard. He tried to keep them all the same size, length, color, shape, and type to keep the experiment as accurate as possible. Then he went inside and got scissors, and two vases that were exactly the same in size, shape, and height. Before he went outside he poured three cups of water in each vase and put two asprins in one of the vases. The other vase had no asprin in it. He divided the flowers into two different groups and cut the stems at about the same spot up on the stem. Then he put 50 flowers in the vase with only water and 50 flowers in the vase that has asprin and water. He measured the experiment for a week by taking pictures of each of the 50 flowers in the vases, and compared them at the end of the week. **==
