REACTION PAPER It is said that effective teacher will use both assessment and evaluation regularly to improve student learning and to guide instruction. Indeed‚ both have pivotal roles in the teaching-learning process yet‚ somehow they do differ in many ways. Assessment and evaluation measure whether or not learning and/or learning objectives are being met. One could look at assessment and evaluation as the journey (assessment) versus the snapshot (evaluation). (Sue Watson‚ 2009) Assessment requires

The objective of this lab was to. First‚ we measured out 2.00g of granular zinc and 2.03g of iodine crystals and added them together into a boiling tube‚ which we labeled "R". After‚ we added a boiling chip into a large test tube labeled "P" and we also labeled an empty regular sized test tube with a "C". When we added 5mL of acetic acid to tube R‚ the solution turned red and was hot. After we add 30 drops of the red solution into tube C and continued to swirl tube R‚ the solution became

The kinetics of the Harcourt-Essen Reaction (Hydrogen peroxide variation) Aims: To find the order of the reaction with respect to the Hydrogen Peroxide (H2O2)‚ Potassium Iodide (KI) and the Sulphuric Acid (H2SO4) by the use of an Iodine clock reaction. Calculate the rate constant‚ mechanism and equation Find the effects of temperature on the rate of reaction The effects of a catalyst on the rate of reaction Find the activation enthalpy (Ea) of the reaction‚ with and without a catalyst Background:

Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect of 0

Megan Wierzbowski Organic II Laboratory Wed. 11-1:50 Title: Grignard Reaction with a Ketone: Triphenylmethanol Part 1 Objective: The goal of this experiment is to learn to make Grignard reagents. The reactions of the Grignard reagents with ketones form tertiary alcohols. These reagents are highly air- and moisture-sensitive materials. We will observe the formation of the Grignard reagents‚ which magnesium metal is transformed into organometallic salts. Experimental Procedure:

Malacanang has declared February 25 as a special holiday for all schools nationwide. People Power Day or Araw ng People Power is a school holiday. This is in commemoration of the 1986 People Power Revolution. Senator Gregorio Honasan‚ a former rebel soldier‚ was one of the major figures in the 1986 EDSA Revolution. As the anniversary of the 1986 EDSA revolution approaches‚ he thinks that there is no reason yet to "celebrate" its anniversary. For now‚ the Philippines can only "commemorate it." "Siguro
