The following is a sample calculation done for 2 mm diameter. The Average time for (2mm) ball =(1.62+1.54+1.60+1.63+1.55+1.78)/6=1.62 sec Terminal Velocity = Distance/(Time (avarge) ) = (0.252 m)/(1.62 s) =0.155 m/s Accordingly

G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III.

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

using a graduated cylinder. It will then be poured into a small Erlenmeyer flask. This will be repeated five times‚ representing the five trials for each catalase treatment. Once the Erlenmeyer flask has been given 5ml of hydrogen peroxide‚ 10ml of the S. oleracea catalase will be measured out and poured into the Hydrogen peroxide filled flask. When the catalase and Hydrogen peroxide meet a reaction will occur and the hydrogen peroxide will be broken down into water and oxygen. The oxygen released from

for the Protection of Human Subjects of Biomedical and Behavioral Research proposed a few ethical principles for researcher over human beings (Shadish‚ Cook & Campbell‚ 2002). For this analysis‚ I will explain those principles‚ I will give examples of research that could violate them‚ and I will suggest modifications that will improve the problems with them. The three principles in the “Belmont Report” are not a regulation for researcher‚ they are standards‚ analytical framework that can be contrasted

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from
