Melissa Benning Introduction The purpose of the coordination complex lab is to determine the absorbance spectra of complexes based on their color. Every complex has its own color which results from the wavelengths of white light it reflects. The complexes will be compared by the color each reflects and by the energy of the waves each absorbs. The purity of the synthesized complex will also be found. Procedure Part I: Preparation of the Complex A sample of copper sulfate pentahydrate (6.285g)

She is also concerned that her students will get hurt if they are not careful at the lab stations. To alleviate her concerns‚ help Ms. Gardner: a. Develop a set of classroom rules b. Create at least three procedures for walking to and working at the lab stations 5. Sierra‚ a student in Ms. Gardner’s science class‚ is shy and often

Midday Break “Finally‚ the just ten minutes more till recess!” I thought as my stomach growled loudly. I was looking forward to recess time! I had eaten a pretty light breakfast this morning‚ and I have an empty stomach which I wanted to fill so badly!

That made me hungrier than I am now! “Ring!” the bell finally rang‚ signalling that it was recess time ---midday break. In a fast motion‚ I fished

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

Joshua Cooper Jonathan Cooper Tyler Allrutz 1/16/14 Physics Tennis Ball Inquiry Goal Purpose When received this lab we had to come up with an experiment that would have to involve testing two tennis balls but one of the tennis ball had to be altered in one way. The way we tested the tennis ball was by dropping them from a certain height and seeing how high they bounce back up. We then would make a graph and then see the relationship between the data. Once finding the relationship we can

ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure
