measurement in lab and in problem solving. Use specific mathematics skills (powers of 10‚ trigonometric functions‚ vectors‚ simultaneous equations‚) to solve physics problems. Identify and solve problems involving constant velocity and constant acceleration. Apply kinematic equations to solve falling body problems. Apply principles of algebra and kinematics to solve projectile problems. Apply Newton’s three laws of motion and principles of kinematics to solve force (dynamics) problems

by heating/burning a portion of the food item and catching the heat released into a known mass of water in a calorimeter. We will also identify units of measuring heat such as calories and joules. We will use basic lab equipment provided in our labpaq and we will use several household items as well. We will follow all safety requirements and standard procedures for this lab. We learned from the chapter that a “calorie: is a unit of energy‚ just like a kilowatt-hour or a joule. These units

C. How would you explain a sand recovery percentage that is higher than the original sand percentage? D. What were potential sources of error in this experiment? A.) The methods I proposed were highly similar to the instructions used in the labpaq manual. Just as stated in the instructions‚ I would have used the magnet to separate iron fillings‚ but I would have thought lastly upon

Report Submitted: September 4‚ 2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # |

PROCEDURE: Finding out the physical and chemical change in matter. There was seven different substances that were being tested; Mossy Zinc (Zn)‚ Magnesium (Mn)‚ Copper (Cu)‚ Magnesium Oxide (MgO)‚ Copper II Nitrate (Cu(NO3)2)‚ Copper II Carbonate (CuCO3) and Sodium Chloride

Mini-Lab Report Objectives: There were two major goals of the “Observing Bacteria and Blood” experiment. The first was to establish a familiarity with the proper techniques for using a microscope. The experiment focused on both the basic components of a microscope (i.e. how to adjust the knobs and levers for the desired result) as well as how do decide the proper objective to use for observing a specimen. The second goal major goal of this experiment was to practice observing live specimens

Zn(NO3)2 into well A3 of the 24-well plate. 4. Place 10 drops of Iron (III) chloride‚ FeCl3 into well A4 of the 24-well plate. 5. Place 10 drops of Copper (II) sulfate‚ Cu SO4 into well A5 of the 24-well plate. 6. Take the metal solids from your LabPaq; there should be one piece each of magnesium‚ zinc‚ and iron plus two pieces of lead. Note: Magnesium and lead oxidize very easily and an almost invisible oxidation layer may coat the metal. To insure good reactions you should scrape the surface

Background examination for the Dominant Thumb Experiment: • Upon reading the literature that the researcher found by googling‚ "Thumb Dominance‚" they discovered that almost every human being has a dominant thumb whether it be the right thumb or the left thumb on top after naturally clasping their hands together. However‚ if the individual tries to force their clasped hands to let the other thumb become dominant it ’s most often described as feeling awkward or abnormal. In 1999‚ a scientist by the
