Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and associate them with everyday household cleaning products. Procedure: In order to complete this experiment‚ I had to set up and organize my lab table. I used my 24-well plate‚ my 96-well plate‚ and the first experiment bag which included all of the necessary chemicals. I also had to gather 3 household cleaning products and a pipet in order to test them as well. The procedure involved was putting 2 drops of

Title: An investigation into the impact of group pressure on an individual’s estimate of the amount of beads in a pot (ginger granules in a jar). IV = Group/Individual DV = Individual beads estimate Abstract This experiment investigated the impact of group pressure on the individual. The hypothesis is that group pressure does indeed impact on the individual and in this case the individual’s estimate of the number of ginger granules in a jar. Participants were asked to make a judgement of

------------------------------------------------- The Mondragon Experiment * Government * Econ By Greg MacLeod | April 4‚ 2009 | 10:28 PM The concept of the corporation reaches back to Roman times. However‚ the modern business corporation evolved radically from its ancient roots into a form with little relation to the purpose as understood by historians of law. Today‚ the typical business corporation seems to be a disjointed entity whereby shareholders seek maximum income‚ labor unions

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

Seth Dennison and Jenna Snyder John Bryan Psychology of Gender 104 10/31/2012 Psychological Gender Experiment For our psychological gender experiment we chose to focus on the topic of memory differences between genders. At first we wanted to figure out if one gender had a better memory than the other‚ but then we also wanted to observe whether or not their memory showed better results when the objects were related to their gender. Therefore‚ the hypothesis we constructed was: If
