was done with “Ominous,” but I combined the short films that portrayed an evil tone. The audience was ready to answer questions after each video. Half the class viewed “Ominous” including the short films following it, and the rest of the films were shown to the other side of the class. For “Ominous” and the short films that followed, 18 out of 22 found that something bad was happening in the scene. In “Happy” and the short films that followed, 16 out of 22 found something happy was happening in the scene. According to the results my hypothesis was correct. The viewer will respond in different ways depending on how music and cinematography are used to affect the tone of a film. 5185
Does Classical Music Affect the Growth of Plants? Afrah Shah and G. Zem (teacher)
Ernest Lawrence Gifted/Highly Gifted Magnet 10100 Variel Ave. Chatsworth, CA 91311
In this study I had a control plant and experimental plant. For the experimental plant I played classical music to it for two hours daily while the control plant was just treated normally. The results showed that classical music does affect affect plant growth since the experimental plant ended up being almost double the size of the control plant. 5186

If Collembola Are Fed Bananas for Food, Will Their Population Increase? Andy Garza and T. Miller (teacher) Holmes International Middle School 9351 Paso Robles Ave. Northridge, CA 91325
The purpose for doing the experiment is to determine if a population of collembola (Onychiuridae encarpatus) will rise if they are fed bananas for food. For a hypothesis, I think that it will make the reproduction rate of collembola go down because it will be too big and mushy to eat for the collembola. Collembola are arthropods that have six legs and are commonly called springtails. One part charcoal and nine parts plaster of Paris were added to a container with water. It was stirred to a consistency of yogurt. Then, it was poured into two petri dishes and allowed to dry. One was labeled control and the other experiment. Both of the petri dishes were watered to make a moist environment for the collembola. Eleven collembola were placed in each petri dish. Yeast was added to the control and banana was added to the experiment. The collembola and eggs were counted at least twice a week using a stereomicroscope and magnifying glasses. In the control at the end there were 67 collembola and 56 eggs. In the experiment there were 123 collembola and 44 eggs. The control had 35% of the collembola and the experiment had 65%. My hypothesis was incorrect and the evidence suggests that the collembola reproduce faster if they are fed banana.

The purpose of this experiment was to test the performance of a solar-powered saltwater desalination device with/without an aluminum foil reflector. Two identical devices were made from general household items and placed in direct sunlight at the same time in the same place; weather conditions were monitored during the experiment. The experiment was conducted six times on different days with different weather conditions. The data showed that the aluminum foil reflector had a significant effect on most days. The results concluded that an aluminum foil reflector did boost performance of the device and that desalination is an admirable way to generate fresh water, with no additional power source.

Effects of Colors, Stem Length and Amount of Color on Carnations A. Nakamura and G. Zem (teacher)
Ernest Lawrence Gifted/Highly Gifted Magnet 10100 Variel Ave. Chatsworth, CA 91311
This study was to determine whether the color of water, amount of food coloring in the water, or the stem length changed the speed of color absorption and the amount of color the carnation ended up absorbing. Carnations A, B, C, D, E and F were all placed in 200 ml of water with two drops of food coloring, except for carnation D, with four drops. Carnations A, B, C and D had a stem length of 50 cm, while carnation E was 25 cm and F was 7 cm. Carnations A, D, E and F were placed in red food coloring, but B had light blue food coloring and C had black food coloring. Carnation A did not end up absorbing much; B absorbed more color overall and had more color near the edges. Carnation C had an overall dark blue color, and D only absorbed a bit more color than A. Carnation E was the fourth fastest flower for the color to start showing; Carnation F was first, C was second and B was third. Carnation F, like I mentioned before, was the fastest to start absorbing color. From these results, I believe that blue is an easy color to absorb; the more blue the food coloring has, the faster it absorbs, and that red doesn’t absorb color very well.

Will Spinach Added to the Diet of Collembola Cause Their Population to Increase? Holmes International Middle School 9351 Paso Robles Ave. Northridge, CA 91325
The purpose of this experiment is to see if a population of collembola increases if spinach is added to their diet. I believed that their population would increase with spinach added to their diet because of the nutrients in the spinach. Collembola are tiny terrestrial and aquatic arthropods. To make environments for the collembola I stirred one part charcoal, nine parts plaster of Paris and water in a small dish. I poured it in two small petri dishes. They were allowed to dry for two days. Water was placed in both of the environments by using medicine droppers. Yeast was placed in both environments for the collembola to eat, and in the petri dish for the experiment spinach was also added. Thirteen collembola were placed in both petri dishes. The collembola were counted as data three times a week for five weeks. The results showed 0 eggs and 6 collembola in the experiment and 7 eggs and 74 collembola in the control. The data suggests that my hypothesis was incorrect, because the collembola didn’t increase with spinach added to their diet. 5190
Which Fruit Juice Has the Most Vitamin C? Marizennia Andres and T. Miller (teacher) Holmes International Middle School 9351 Paso Robles Ave. Northridge, CA 91325
The purpose of this experiment is to determine which fruit juice has the most Vitamin C. Based on my research, I believe that the guava juice contains the highest amount of Vitamin C. An indicator for Vitamin C was made by boiling 4 cups of water and adding 1 ml of cornstarch. The liquid was then poured into five test tubes and eight drops of iodine solution were added to each test tube that caused it to turn dark blue. I added 1 ml drop of each juice to each test tube one by one until the solution turned clear. Then I carefully counted the drops and recorded them as my data. This was repeated six times for each of the juices: lemon, lime, apple, orange, pine-
