Then, hit Enter”: 110 input d 120 if d < 1 or d > 7 then print “CHOOSE A NUMBER FROM THE LIST!!!” go to 110 My hypothesis was that the program would be able to suggest clothing for the user to wear, based on the information input by the user. The program simply asks the user what the day of the week is, weather conditions and occasion. What I learned was that my hypothesis was right. As long as the user inputs factual data, the program quickly analyzes the data and gives the correct response. In conclusion, Easy Dress can save people time and help them look good. 5201

Oral Health

Calib Morgan and A. Antoniou (teacher) Robert Frost Middle School 12314 Bradford Pl. Granada Hills, CA 91344

My project is about oral health. I am doing this project to see the effect toothpaste has on a young person’s oral bacteria and an older person’s bacteria. After doing my research and speaking with an expert I have found that oral bacteria can affect more than just your mouth. Oral bacteria are caused by not taking care of our teeth and tongues. It is very important to brush our teeth and tongues and also floss the teeth and use mouthwash. If we do these steps at least twice a day we can help prevent many diseases. Using toothpaste is important for killing bacteria and for refreshing one’s mouth. If oral health is not taken care of, it can lead to gum disease, plaque buildup, lost teeth, cavities and bad breath. In addition, the bacteria can travel into the bloodstream and affect the heart. People need to understand the importance of keeping their mouths healthy. For my experiment, I took a swab from a 14-year-old and a 75-year-old person’s mouth before brushing teeth and after brushing teeth. I observed the bacterial growth on petri dishes and found that the growth of the older person’s sample before brushing teeth was much more than on any other petri dish. The petri dishes that had a sample of the after brushing teeth had a very small amount of bacteria compared to the petri dishes that had a sample of the before brushing teeth. This showed that brushing teeth is very important because it kills 99% of the bacteria in the mouth and protects people from diseases caused by oral bacteria. 5202

What Are the Differences Between Child and Adult Dreams? Choice Plasencia, Stacy Kim and A. Antoniou (teacher) Robert Frost Middle School 12314 Bradford Pl. Granada Hills, CA 91344

The purpose of our experiment was to figure out the differences between child and adult dreams. We also wanted to figure out what caused these differences. Our hypothesis was that children would have more nightmares than adults because children have a lot of unanswered questions about the world and they use their imaginations to answer them. Our hypothesis for the adults was that they were mostly going to have dreams about real-life situations rather than a fantasy world. For our experiment, we surveyed 20 children ages 5-17 and 20 adults over the age of 20 and compared the types of dreams and their frequency. We also did a lot of research to understand what dreams are and how they work. We found out that children have a

higher ratio of REM sleep than adults. REM is rapid eye movement, which is the normal stage of sleep in the period of the night when people actually dream. The results of our investigation were that 10% of children dream more of what they see on television, whereas 0% of adults have these kinds of dreams. Sixty percent of adults have dreams of real-life situations and 75% of children have dreams of unrealistic situations. The children’s average frequency was 5.15 times a week and the adults’ average was 4.75 times a week. In conclusion, children have more unrealistic dreams and a higher frequency than adults. 5203

Will a Cold or Hot Tennis Ball Bounce Higher? Chris Dozal and A. Antoniou (teacher) Robert Frost Middle School 12314 Bradford Pl. Granada Hills, CA 91344

The purpose of my experiment was to see if a cold or hot tennis ball would bounce higher. My hypothesis was that the cold tennis ball would bounce higher. I used tennis balls that were 85 degrees, 100 degrees and 50 degrees. I dropped each ball five times from 1 meter. The 85 degree ball’s average was 46 cm. The 100 degree ball’s average was 52 cm. The 50 degree ball’s average was 13 cm. My results showed that the hot ball came in first, the 85 degree ball second and the cold ball last. My hypothesis was wrong and my conclusion is that a hot tennis ball will bounce higher than a cold tennis ball. Maybe tennis players can use this as an advantage in their matches. 5204

Which Energy Drink Affects Blood Pressure and Pulse the Most? Chris Jimerson, Gio Osterman and A. Antoniou (teacher) Robert Frost Middle School 12314 Bradford Pl. Granada Hills, CA 91344

For our science fair project, we tested energy drinks and saw which one gave us the most energy. We tested Rockstar-Juiced, Java Monster-Loca Moca, and Red Bull. For this experiment we both drank 8 oz. of each of these drinks, and then we tested our blood pressure and pulse. We tested our blood pressure and pulse once before we drank it, once half an hour after we drank it, and then again an hour after we drank it. For the Red Bull, Gio’s blood pressure, before we drank it, was 153/114 and her pulse was 82. A half an hour later her BP was 76/47 and her pulse was 110. An hour later, her BP was 88/47 and her pulse was 92. Chris’ BP before was 76/39 and his pulse was 75. A half an hour after, his BP was 89/56 and his pulse was 86; an hour later his BP was 91/54 and his pulse was 65. For the Java Monster-Loca Moca, Gio’s BP before was 87/55 and her pulse was 71, a half an hour later her BP was 80/55 and her pulse was 79, and an hour later her BP was 96/60 and her pulse was 64. Chris’ BP before was 101/67 and his pulse was 105, a half an hour later his BP was 105/77 and his pulse was 137, and an hour later his BP was 54/28 and his pulse was 74. Finally, for Rockstar-Juiced, Gio’s BP before was 79/51 and her pulse was 73, a half an hour later her BP was 65/36 and her pulse was 85, and an hour later her BP was 138/109 and her pulse was 127. Chris’ BP before was 97/64 and his pulse was 70, a half an hour later his BP was 109/66 and his pulse was 85, and an hour after his BP was 112/71 and his pulse was 71. We both have different weights; Chris weighs 121 lbs. and Gio weighs 101 lbs., but the drink that increased both our pressure and pulse the most was Rockstar-Juiced.
