Withers

__ Questions: __ In a Paragraph or more tell the class your Interests, favorite subjects, favorite topics in science, least favorite topics in science, and what you Would Like to Learn This Year.

=Hello, I'm Erik Withers and I'm going to tell you a few things about me. First, I'd like to tell you my interests. One of my interests are video games because it gives me something to do afterschool and even though they have no benefits for me or helps me in any way, they're still pretty fun. Another one of my interests is football because it's good excercise and it's a great to have fun on the weekends and after school. Now, my favorite subjects are language arts and physical education. Language arts because there's more to it than just reading and writing. You can do fun activities with your friends like venn diagrams and word searches and stuff like that and P.E. because it's seems like one of the easiest classes at the school because basically all you have to do is put the CCMS P.E. unform on, go outside and do whatever the coach decides you're going to do for about an hour or so,and that's it. Easy A. I also like P.E. because most of my friends are in my class too. My favorite topics in science are astronomy and ufology. Astronomy is the study of planets, stars, comets and more and the reason I like astronomy is because I like to learn about the planets and facts about them like what they're made of, and how many moons they have, and how far they are from the sun and stuff like that. Ufology, on the other hand is the study of UFO's (unidentified flying objects). Even though they don't teach this at CCMS, I'm still interested in it because I like to hear about sightings, and stories on the news about crop circles and cattle mutilation and more very interesting things. My least favorite topics in science are botany and anatomy. Botany because I find nothing very interesting with plant matter or anything concerning it and anatomy because I learned a lot about anatomy in 2nd and 3rd grade and to have to be taught something you already know is really boring. The thing I would like to learn this year in science class is toxicology because I don't know a lot about this topic, and it seems like a cool topic to learn about.=

Problem Statement: Which factor effects the rate of evaporation most-wind speed, temperature, or humidity? Hypothesis: I think temperature effects evaporation the most.


 * ===Problem Statement: What increases the rate of evaporation . Hypothesis:Exp1-If I place all 3 liquids on medium heat on a stove with equal amounts of liquid, the salt water will evaporate quicker. .Materials- Water, salt, spoon, stove, 3 pots, ruler, measuring cup, sugar, timer. . Procedures: 1- pour 1 and a half cup of water in all pots / 2- put a half cup of salt in 2nd pot and a half cup of sugar in 3rd pot / 3- Set heat to medium on stove and put pots on stove. 4-put on timer for 30 minutes and measure water every 5 minutes . Variables- Independent : the type of liquid . Dependent: amount of evaporated liquid. Controlled variables: amount of liquid, type of pot, composition of pot, amount of heat, amount of time. Conclusion: my hypothesis was correct. The salt water evaporated quicker. Hypothesis:Exp2-If I put all 3 pots and fill them water one with increased temperature, and one with smaller amount of water, and one regular I think the one with the smaller amount will evaporate quicker. Materials: water, 3 pots, stove, ruler, timer. Procedures: 1-take out 3 pots and fill 1 with 1 cup of water, the 2nd with a hotter preset temperature of the water with 1 cup and the last with a half cup of water.2- put all pots on stove on medium heat and set timer for 30 minutes and graph and measure every 5. Variables: Independent: factors effecting evaporation Dependent: amount of evaporated water controlled: type of liquid, temperature of stove, type of pot, composition of pot, amount of time Conclusion: My hypothesis was right. When tested the smaller amount was losing 1-2 every 5 minutes .===
