Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Radial Immunodiffussion (RID) Christian Crespo 18 October 2013 Immunology Lab Report Purpose of the Experiment: The objective of this experiment is to quantitatively observe the foundational reaction in our Immune system; the Antigen-Antibody interactions. The Ouchterlony procedure is what will be used in this lab to detect nature of the antibody interaction. The orientations of the band will provide more information about the interaction of antibody and antigen

conditioning in rats. The purpose of the experiment was to condition rats to suppress certain hunger behaviors such as water licking. Burdick and James paired the neutral stimulus of white light with shock in a “test chamber” to see if rats would develop an association between the two stimuli. Naturally‚ shock induces a fear-like freezing behavior‚ and after being conditioned the rats displayed the same behavior but only to the white light. Furthermore‚ they would then place the rats back in their

Introduction: The cardiovascular system has multiple components that work to ensure an enough oxygen is supplied to the muscles‚ both at rest and during exercise. The objective of this laboratory session was to measure‚ and compare how the cardiovascular system responds to dynamic and isometric exercise. The research question for this lab was “What is the effect of different exercise modalities on the cardiovascular system?”. In response to this research question‚ the following hypothesis was formed

closer the heart rate should be to the resting heart rate of the Daphnia. Possible errors that could have gone wrong are the duration given to allow for the absorption of the different concentration of salt solutions due to the limited time during the lab period and the distinguishing of the separate heart beats and the inaccuracy of a constant time being off by points of a

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can
