This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

The reason for performing this experiment was to test the agnostic behavior coming from the male Betta fish. This experiment was conducting by taking a male Siamese fighting fish and placing its fish bowl next to a mirror so it would be able to see his reflection. We also exposed the fish to many others to see if the behavior was the same or different when placed next to: a goldfish‚ a female Betta fish‚ and a zebra fish. My hypothesis was supposed by this experiment and it was observed that the

Projectile Range Versus Angle Intro: First off‚ what projectile motion is motion in two dimensions in both X & Y directions. The only force on the projectile is gravity. With gravity being a presence and a factor in our everyday lives and in this experiment‚ gravity will push down on the projectile forcing it back down to the ground. For example if someone shot a cannon straight and there was no gravity then the cannon would keep traveling at a constant speed‚ go farther and travel in a straight line

Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate. Then‚ we filled 250 ml beaker with 125

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast
