1 Problem Will the flower petals change color if they are put in food coloring? Hypothesis I think that the flower petals will change color when they are put in food coloring. Materials The materials for my science fair project are: Carnation flowers food coloring water Cups Knife

2 Procedures Step1:put one hole cup of water in each cup. Step 2: put the flower in the cup. Step3: put 1 drop for the first cup 5 drops for the second cup 10 drops for the there'd cup. Step4: let it set for a night and check on the the next day. Step5: need to record each day. Step6:need something to stir the food coloring Why is the one drop not working I think it is the ingreedeans and it is how many drops. why do you think the five drop is the most colorlful I think it is the in ingreedeans and there is only one color in sted of two colors. Why is the ten drop not as colorful as the five drop I think it's because there is two color sand the stem sukup to different food coloring.

3 Data 1 drop Hours Spent in Water 5 hours I did not see any color on the petals. 24 hours 1 day I did not see any color on the petals. 48 hours 2 days I did not see any color on the petals. 72 hours 3 days I did not see any color on the petals, and the flower is starting to wilt. 144 hours 6 days The flower petals have not changed one bit and the flower is dead even though there is still water in it. 5 drops Hours Spent in Water 5 hours I did not see any color on the petals. 24 hours 1 day I saw a little bit of color on the edge and when I looked in the middle I saw it a little. 48 hours 2 days Now I can see the food coloring all over the place now. 72 hours 3 days The flower petals are very colorful, however the 5 drop flower is more colorful than the 10 drop flower. 144 hours 6 days The entire flower is colorful. The color has spread everywhere.

4 10 drops Hours Spent in Water 5 hours I did not see any color on the petals. 24 hours 1 day I saw a little bit of color on the edge and when I looked in the middle I saw it a little. 48 hours 2 days Now I can see the food coloring all over the place now. 72 hours 3 days The flower petals are colorful, however the 5 drop flower is more colorful than the 10 drop flower. 144 hours 6 days The flower has some color showing up through most of the flower, but it s still not as colorful as the 5 drop.

5 Research Roots Roots anchor plant in the soil The root suks up the water Tree roots are very strong and are very hard to chop. The roots are to made to support the leaves and the root are made so the plants won't be flying all over the place. The roots are covered by soil and dirt and the roots have hair and have a hard job there job is to drink the water for the leaves and some time the the root is very long or short The roots can have hair. Wikipedia.com Anderson, James: Energy from plants. Stem A tree trunk is similar to the stalk of a grass plant. Both are stems. Stems have two important jobs. They move food,water and minerals between roots and the lefs. They also hold the plant up. So it's leaves can get sunlite The stem has two important jobs.the first job is carrying the food to the leaves. The second job is moving the water to the leaves too. The stem travels the water and the most important job for the plants it controls the water it is like a vaccum that will suckup the water to get the leaves and then the leaves will drink the water. The plants can die if too much water or not as much water and if their is sun the plant won't die too if their is no sun it won't die the root and stem have the hardest job of a plant because the root has to drink the water and the stem has to make the water go to the leave.
