Pulleys Lab
Daniel Nam March/5/2017 BLK: 3 Pulleys Lab Question How do Pulleys effect the input/output of a system? What is the ideal mechanical advantage of a system? Concept In an ideal system of pulleys, all the energy is transferred from the input to the output without any losses to friction and other forces. Theoretically the efficiency of a system should always be 100% but in real life applications it will always be less than 100% due

Glowing Bacteria Lab
Bio 11H lab Introduction: In this lab we are going to make protein glow by bacterial transformation. Bacterial transformation is done by inserting DNA into bacteria where it will replicate. It uses an inducible promoter to regulate gene expression. We used a special RNA Polymerase (T7) which is controlled by the LAC promoter. Without the T7 polymerase glowing proteins could not be expressed. Normally the Lac repressor is activated making the glowing proteins non expressible.

Physics 11 Light Lab
Biology 12 AP - Ulcer Buffer Lab Purpose: To observe and compare albumin or alka-seltzer’s ability to control pH levels, in order to see which would be a better buffer and therefore a better treatment for a stomach ulcer. Hypothesis: The Alka-Seltzer drug may work better, because it would mostly likely be more basic than the albumin seeing as it contains baking soda as one of its key components which is often used to neutralize

Solubility Product Constant Lab
Introduction: When a salt of low solubility is added to water, only a few ions are formed, and most of the salt remains undissolved. In a saturated solution, the solid dissociates into ions at the same rate that the ions reunite to form the solid. In other words, a dynamic equilibrium exists between the undissolved solid and the ions in solution. An undetermined amount of dissolved salt exists in equilibrium with the solid. The concentration

Kinetics Lab
Introduction The kinetics lab was conducted in order to determine the rate law and activation energy for the bleaching of brilliant blue dye. In order to accomplish this, colorless solutions created as a product of the decomposition of the dye, a spectrometer and Beer’s Law were utilized. Additionally, two different temperatures and the two-point form of the Arrhenius equation were utilized to determine the reaction’s activation energy. Results and Discussion Two experiments, one using room

Physic Lab Report
LAB 02: FREE FALL THEORY The purpose of the experiment was to measure and confirm the acceleration a is constant and a= 9.8 m/s2 due to gravity by timing a free-falling ball. Assumptions: There is no air resistance. Acceleration x_f-x_0= v_oy+1/2.a.t^2 x-0=1/2 a.t^2 x= 1/2.a.t^2=>a=2x/t^2 PROCEDURE Using a receptor pad to collect the table position vs time, with the height range 5cm to 120cm. The height is the distance from the pad to the ball.
