Petri Dishes Bacteria Cells
1,566 wordsIn this lab we observed the growth of bacteria in a conjugation and transformation experiment. We expected the mating plate of the conjunction to grow and the bacteria on the transformation plates to grow also. We also practiced using aseptic techniques to clean the lab benches and to keep the bacteria from being contaminated from outside bacteria. This lab will take a total of 2 days because of the observations that need to be made. The parts of this paper will explain the procedure and the obs...

Cm M
1,324 wordsThe purpose of this lab was to find that gravity of Earth is indeed 9. 8 m / s /s (the The theory, according to Galileo, is that two objects have the same acceleration if dropped from the same height will land at the same time at the speed of 9. 8 m / s /s as long as there is no air resistance. To have an understanding Galileo's theory of acceleration, certain terms and equations must be known. Acceleration is defined as the change in velocity divided by the time interval which the change of vel...

Positive Effect Classical Music
828 wordsThe purpose of the memory lab was to determine which environments are most suitable for memory retention. The participants of this experiment were the students enrolled in our GSC 101 physical science class. Ages ranged from 18 years of age to possibly 50. Of these participants we had a wide range of educational majors, ethical background, and genders. All participants were required to submit a list of thirty common words to be used in the experiment. The testing procedures started at approximat...

Test Tube M L
1,232 wordsLab Report 1: Separation of Proteins Abstract/Summary: "Proteins account for more than 50 % of the dry weight of most cells, and they are instrumental in almost everything organisms do" (Campbell, 1999). The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology. In order to study proteins we must first know how to separate then quantify the amount using basic princi...

Lab That Helped Lab That Gave Labs
609 wordsThroughout this year, I have greatly enjoyed doing labs in Physics class. Not only did I have fun while doing these labs, but also learned a lot from them. By doing these labs, the abstract concepts that I learned by reading the textbooks came alive; I was able to experience firsthand the wonder of physics. The lab that I enjoyed the most doing was the Egg Drop Lab. It is quite obvious why anyone would like doing this lab. It was very interesting trying to come up with the container that would k...

Evaporating Dish Aluminum Foil
2,222 wordsPurpose: To conduct experiments and to determine whether they are physical or chemical changes Pre-Lab Notes: Before we conduct these experiments there are some topics that we must discuss. As I stated in the purpose, in this lab we are going to be looking at some experiments, and we have to determine whether they are a cause of chemical or physical changes. The purpose for all the labs that we will be doing will be the same. During a chemical change a new substance is formed, it is irreversible...

1,768 wordsThe objective Don John Purpose The objective of this lab is to introduce the Bipolar Junction Transistor (BJT). A BJT is a three terminal device composed of an emitter, base, and collector terminals. In this lab we will introduce two major types of BJT? s: npn and pnp. The first, npn, has an n-type emitter, a p-type base and a n-type collector. On the other hand the pnp has a p-type emitter, a n-type base, and a p-type collector. Also the transistor consists of two major pn junctions, the emitte...

Active Transport Membrane Potential
2,258 wordsEffects Of Solutions On Ion Transport Across Membranes Abstract Concentration gradients exist between two different salt molarity solutions on opposite sides of a membrane. Movement of ions across these sides can be achieved by either active or passive diffusion. In our first three experiments we used these concentration gradients to determine the characteristics of selective permeability of an artificial membrane to potassium chloride (KCl), the potential difference across the skin of a frog, R...
