Science Notebook Layout DON’T COPY UNDERLINED TEXT Mrs. Aguirre’s Webpage: 1 Scientific Method Lets Try: Eddie gives his mother a bunch of roses for Mother’s Day. She fills a vase with water, trims the ends of the flower stems, and arranges the roses in the vase. Then she remembers that she heard from a friend that putting an aspirin in the water helps the flowers stay fresh longer. She goes to the medicine cabinet to look for aspirin. Eddie’s sister Kela comes into the kitchen and sees the flowers. She said she heard putting a few drops of bleach in the water helps keep the flowers fresh. She thinks it is because the bleach kills the bacteria in the water. Eddie thinks it seems strange that aspirin or bleach would be better than plain water. He asks his mother if they can do an experiment to find out whether the aspirin or bleach will make the flowers last longer. She thinks it is a good idea and finds some smaller vases to hold the flowers. 1. What are the observations that Eddie has made? 2. What question does Eddie want to answer during the experiment? 3. A.What hypothesis would Eddie’s mother make based on the information she heard from a friend? 3B. What hypothesis would Kela make? 3C. What hypothesis would Eddie make? 4. Test the hypothesis with an experiment Eddie, Kela, and their mother divide the flowers into three bunches of four flowers each. They mix the flowers so the bunches are as identical as possible. They put water in the vases. Into one vase, they add an aspirin, wait for it to dissolve, mix the water, and add the flowers. Into another vase, they add three drops of bleach, mix the water, and add the flowers. The flowers are put into plain water in the third vase. A. What 2 things about the water should be the same for all 3 vases (controlled variables)? B. Independent (experimental) variable: C. Dependent (measured) variable: 5. Draw conclusions based on the test One week later, they look over their data and compare the flowers. The flowers with the aspirin in the water have lost a total of seven petals and have many brown spots. The flowers with the bleach in the water have lost a total of two petals and have hardly any brown spots. The flowers in the plain water have lost four petals and have a medium amount of brown spots. A. Based on the data, what should Eddie, Kela, and their mother conclude about the experiment?

Hypothesis: (write your answer here) Answer questions 2a,b,and c in your notebook- do not write the questions!! 2. Stop and think a. Why are centimeters better for measuring human wingspan and height than meters? b. Look at the difference between your estimate and the actual measurements (the last column in Table 1). Did the difference get lower as you took more measurements? Explain these results. c. Based on the results of your measurements, do you think there is a relationship between human wingspan and height? If so, what do you think it is?
