Project # J0101 Category: Animal Biology - Jr Student: Amy Figueroa Grade: 8 G: F School: South Gate Middle School Title: Anemon-EATS My question is, "How can temperature change affect the eating habits of Actiniaria?" In my experiment, I feed Actiniaria in different seawater temperatures. The temperatures were 7,13, and 22 degrees Celsius. My hypothesis is: If the water temperature is lower than 13°C, the anemones will consume more to maintain their body temperatures. If my hypothesis is supported, this will emphasize the importance of protecting the planet. Global warming is not just warming the Earth but it is causing the Earth to experience extreme temperatures. There is a higher chance of consuming plastic with harmful chemicals that were not intended for digesting if they eat more. With higher water temperatures, body temperatures will also rise, meaning anemones will eat less. The independent variables of my experiment are the water temperatures. The dependent factors are my recorded data points which is how long it takes for them to react to food. All throughout my experiment, I kept the food and timer the same so I could get reliable data. I fed and timed them 50 different times in each water treatment. I saw the anemones react quicker in lower temperatures. This supports my hypothesis. A factor that could have affected my results was that some anemones might have not been hungry. I also observed the anemones had a delayed reaction in the warmest temperature. My experiment can be expanded in many ways but this will provide so much information on the effect of temperature change on the eating habits of Actiniaria. Project # J0102 Category: Animal Biology - Jr Student: Antonio Zamudio Grade: 8 G: M School: Sun Valley Magnet - Junior Division Title: Flies Like Fruit My project is showing if flies would like an apple slice or an oreo better.It took me three weeks to finish the whole poster in general. I drew and colored my steps that I did. My plan is to show anyone eating these foods you need to have them covered. The main colors I used were black and red. I used a printer for the flies next to the title. The biggest challenge I faced was the wind because when I thought of this it was hot, but doing it was windy. I thought of this project because we had a party and when I was cleaning up I saw flies gathered around different foods. I wanted to figure out if flies would like healthy stuff or something unhealthy more. To test my project all you need to do is first cut a 2 liter bottle from the top so that you can work with it. Next, you put the food items at the bottom of the bottle, in my case I used apples and oreos. Any food would work for this. After that you need to put the fly trap so that the flies will get stuck in it. You must record your stats everyday. Project # J0103 Category: Animal Biology - Jr Student: Charlotte Greene Grade: 8 G: F School: Archer School for Girls Title: The Mortality Rate of Daphnia when Exposed to Copper Sulfate My objective is to observe the effects of copper sulfate on the mortality rate of Daphnia. To do this, I put 10 Daphnia each in eight 250 mL beakers that contained 0 ppm, 25 ppm, .75ppm, 1ppm, 2ppm, 3ppm, 5ppm and 10ppm of copper sulfate. All copper sulfate used was pure and first dissolved into water before the appropriate amount was added to the beaker. I also attached oxygen pumps and air stones to the beakers which allowed the Daphnia to breathe. My experiment was repeated for 13 days, the first three were to make sure the daphnia adjusted properly and that my environment was healthy for them and the next ten for testing. The result of my experiment is that copper sulfate is indeed poisonous to Daphnia, but Daphnia do have a certain amount of resistance to it. When daphnia are exposed to more than two ppm of copper sulfate they will die very fast while two or less ppm will be able to keep them healthy enough to survive and even reproduce. In conclusion, copper sulfate is poisonous to Daphnia, but will not be enough to kill them all within 2-3 days. The experimental groups 2, 1, and .75 also had a higher mortality rate than the control group which leaves the question of whether or not the right amount copper sulfate is healthy for daphnia. 2019 LACSEF projects Page: 1 Project # J0104 Category: Animal Biology - Jr Student: Christian Mueller Grade: 7 G: M School: American Martyrs School Title: Effects of Dietary Supplements on Brown Planaria The purpose of my experiment was to find out which supplement (vitamin A, vitamin D3, vitamin E, zinc, sugar, and protein) most affected planaria’s regeneration process. My hypothesis was: The sugar supplement will assist the planarians in regenerating lost tissues the most. I added fifteen brown planaria to each petri dish. I then cut five planarians in half, so that there are ten planarian pieces to find an average on. I then added two milliliters or two milligrams of a supplement into each petri dish. Each cut planarian piece had their regeneration progress (length) recorded three times over the course of five days. The results of this experiment are as follows: the average vitamin A planarian length decreased 2.2 mm, the average vitamin E planarian length decreased 1.2 mm, the average vitamin D3 planarian length decreased 1.3 mm, the average sugar planarian’s length decreased 0.52 mm, the average zinc planarian length decreased 0.75 mm (over the span of three days), but the average control planarian length grew 2.6 mm. These results did not support my hypothesis. My experiment showed that dietary supplements harm planaria’s regeneration process. I really enjoyed preparing for and carrying out my experiment; I learned a lot about planarians, different vitamins and minerals, and how both can affect each other. Project # J0105 Category: Animal Biology - Jr Student: Ciara Cabrera Grade: 8 G: F School: South Gate Middle School Title: Abalones and their food preferences My project is testing the food preferences of Abalones. I hypothesized that the Brown algae would be preferred over the red algae because it is more common in their habitat. The materials i used were 2 thermometers, the Red algae and the Brown algae, 2 trays, a pitcher, , a timer, a scale, and Abalones. i first prepared my testing area, conducted my experiment, and then recorded my results and repeat the process. for the following trials. my results indicated that red algae was preferred over Brown algae because more abalone ate Red algae than Brown algae. based off of this information, I have found the preferences of Abalones food taste. This experiment can help sea nurturers feed Abalones food that they favor of. My experiment took about 2 weeks to conduct, which includes testing, data collection, and my writing. Project # J0106 Category: Animal Biology - Jr Student: Joseph Kim Grade: 8 G: M School: Beverly Hills Middle School Title: That's Bone-Chilling My objective was to test which of the drinks Coca Cola, Sprite, Lemonade, and purified water was the most harmful to chicken bones. I conducted 3 tests at the same time for accuracy. I labeled the cobtainers, then, I put the chicken bones into each of the containers and pured 12 ounces of each liquid that matched the labels on the containers. Then I put everything away and waited for 24 days instead of taking information at the start because of an adverse problem which I had encountered. On the 24th day of the experiment, I used a scale (to weigh in grams) to interpret my results. I recorded each mass of the bones and waited 2 more days. I repeated this same process, except that I found the mass lost during the 2 days. I kept repeating this process every teo days until the 30th day, where I also dound the total mass lost during the 6 days. The total average mass that Coca Cola lost was around 0.53g, Sprite was around 0.57g, lemonade was 0.8g, and purified water was 0.2g. The results did not support my hypothesis. I hypothesized that put of the four drinks, that Coca Cola would be the most harmful, then Sprite, then lemonade, then water. The actual results from the most to the least harmful was: Lemonade, Sprite, Coca-Cola, and purified water. This was likely because of the acids found in these drinks. 2019 LACSEF projects Page: 2 Project # J0107 Category: Animal Biology - Jr Student: Kimberly Fuerte Grade: 8 G: F School: South Gate Middle School Title: Sea Anemone My research question is if a sea anemones eat more in the cold or in warm water. My hypothesis is that they are going to eat more in the cold water because normally when anyone is cold, you have to build up your body fat so that you could find a way to stay warm. I found out that my hypothesis was correct, sea anemones do eat more in cold water. I think this is important because I think it's good to know so that aquariums could kinda have an idea on how to take better care of there sea animals. Maybe if they decide to rescue other animals they could have some good information so that they could take care of them a lot better. Sea anemones are very interesting animals to study that I think people should pay more attention to and get to find out more interesting facts and things about these very amazing sea animals.
