is by eating chocolates. To confirm this assumption‚ the experimenter‚ Victor Seo has developed an experiment to prove the hypothesis: “people who consume lots of chocolate will produce more acne than people eat less chocolate. 400 students of teenagers with grades ranging from 9 to 11 will be examined divided into four groups each consuming 1 bar‚ 3 bars‚ 6 bars‚ or 10 bars daily. This experiment will remain over a time period of a month. Meals will be served in equal amounts and the amounts of

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria

DESIGN AN EXPERIMENT: THE BIGGEST BLOWER EXPERIMENT Design an Experiment: The Biggest Blower Experiment Problem Statement: You have a pack of Hubba Bubba Bubble Gum. Does the amount of sugar in this gum affect the size of the bubble you blow?? Hypothesis: I think that sugar in any gum affects the size of the bubble you blow. I think this because I was watching “The Next Great Baker” and someone was melting sugar and when it cooled off a little he used a balloon blower to make bubbles out of

Describe a mingle activity you might create for a new class of intermediate level students to help them introduce themselves to each other. The best way to help students mingle with each other and enhance their proficiency in the English language is by using ice-breaker activities. This effectively encourages the participants to interact with each other freely. An activity which might be done is a ‘getting to know you’ activity where the participants will be given a certain period of time to gather
