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

Cognitive mapping What is cognitive mapping? A cognitive map is a type of mental representation which serves an individual to acquire code‚ store‚ recall‚ and decode information about the relative locations and attributes of phenomena in their everyday or metaphorical spatial environment. It is the means through which people process their environment‚ solve problems and use memory. This concept was introduced by Edward Tolman in 1948. Cognitive maps have been studied in various fields‚ such as

without trivializing the need to sustain and drive a motivated high performing workforce. The company’s needed to sustain in a competitive environment‚ gave rise to the need to understand and learn to establish the context of competency mapping. Competency mapping is the process of identification of the competencies required to perform successfully a given job or role or a set of tasks at a given point of time. It generally examines two areas: emotional intelligence or emotional quotient (EQ)

# 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

Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

to a variable-frequency ac supply‚ which can maintain a constant air-gap flux in the motor by an inverter. 2.3 Synchronous speed When the balanced three-phase currents flow through three-phase stator windings of the motor‚ a rotating magnetic field or magnetic motive force (mmf) is produced. The speed of the rotating mmf is called the synchronous speed and it depends on the supply frequency and the number of the poles in the motor‚ as shown in equation 1. [pic]

What keeps the stopper moving in a circle? Purpose: Relate the variables involved in uniform circular motion Hypothesis: I predict that the velocity of the stopper will increase as the radius is shortened. Rubber stopper with a hole PVC tube or wooden spool 1. Measure the mass f the stopper and washer‚ m‚ and record it in the data and observations section. Then‚ prepare the experimental apparatus as shown in figure A. 2. Throughout this experiment‚ you will need to maintain a constant

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

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
