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

# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

Free trade: For or against? Muntianu Ioana Hassan Chaudhry Anna Dvurechenskaya Guliza Toran 2/18/2013 Ioana For centuries economists have sustained free trade as the best free trade policy. Even so‚ after a more in depth analysis one can notice certain advantages and disadvantages of free trade. This report explains the concept of free trade‚ the implications of engaging in free trade and the pro and con opinions along with an explication of certain theories related to the concept.

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

Free fall and the acceleration due to gravity Problem/Question: How do you measure the acceleration of a falling object? Hypothesis: by measuring velocities of a falling ball then applying the data into equations numerous times‚ the results should approach to the acceleration. Variables: A: Independent Velocity B:Dependant Acceleration C:Constant Distance (photo gates) Materials: Photo gates‚ Clay ball‚ Photo gates machine.

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

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

Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three
