primary objective. The experiment was divided into two parts‚ first‚ mixing two aqueous solutions of ionic compounds. The second part involved the observance of heating and combustion reactions‚ using the supplied solid elements and compounds. Experiment and Observations: The first part of this experiment involved mixing the compounds‚ provided by Hands-On Lab‚ in a 24-well plate. Aqueous solutions of ionic compounds were mixed in eight separate wells. A few drops of each solution were mixed in a well

perspective obtained‚ and eventually the best alternative selected‚ when compared to designing only one solution and hoping it will solve the problem. All the benefits of the systematic approach to problem solving have been listed on p. XX. When determining the future COULD-BE scenarios‚ a number of factors were taken into account: 1. The scenarios need to be realistic and viable 2. They need to be “interesting”

ensure that it works well enough for this experiment. In addition‚ make sure each piece of equipment used is washed and dried before conducting the experiment. Lastly‚ the speed of the drip was a possible error. If the group member in charge of determining the speed of the drip needed let out as small as one single drop more‚ this could alter the entire results of the experiment‚ resulting in poor results. This human error is difficult to improve‚ but patience and concentration could potentially terminate

Determining acceleration due to gravity by three methods Purpose: To use three different methods to determine the acceleration due to gravity and see which is more accurate. Also to give us practical application and proof of the 9.8m/s/s law. Materials: Eraser‚ Video‚ stop watch‚ 2M stick Procedure: We measured 2M from the floor to a certain spot on the chalk board. Then we measured by hand with a stop watch how long it took for the eraser to hit the floor. In the video they used a ball

Determining Effective Orientation and Training Methods When one thinks of the word “training‚” what comes to mind? [Writing suggestion: Unless in a quote or a title‚ avoid rhetorical questions in academic writing. A good idea is to provide answers‚ not questions] Teaching‚ conditioning‚ practicing‚ and building are a few words to explain it. It goes much deeper than that though‚ and it is necessary during the life of employment

Jefferson Block 7/8 October 8th 2012 Electrostatic Gedanken Lab Group Gamma Objective: The objective of this lab is to determine the charge on a pith ball. Hypothesis: I fully believe that the charge of the pith ball will be positive. The formula I will use to prove this is Coulomb’s Law‚ (Fe=(k*q1*q2) / r²). ‘Fe’ is equal to the electrostatic force between the spheres‚ measured in Newton’s. It is also a vector quantity‚ and it’s in absolute value. Secondly‚ ‘k’ is equal to Coulomb’s law constant
