BEAN LAB My hypothesis was the white beans would stand out but the black and green beans would be camouflage. For my prediction I said that if the predator consumes more white beans than black. Therefor‚ the white bean population will decrease. In the “beetles” environment the predominant colors are brown‚ green‚ black and tan; and the predominant colors for beans being brown‚ black‚ green and white. Knowing the predominant colors of the environment and of the “beetles” would show that the white

We also get to use whatever materials we want as long as our product is or is smaller than 20cm. II. For my project I used Styrofoam‚ tinfoil‚ insulation‚ silicone‚ and a cork. I used the Styrofoam as a box to put

Throughout the week in the toxicology lab‚ I was acquainted with distinctive sort of tests and I got the opportunity to find out about the following: 1- hTSH test (Human thyroid stimulating Hormone): - Add calibration and +/- controls‚ before starting the punching process. - Add hTSH assay buffer + stock solution. - Put the plate on a fast quick shaking for 10mins‚ and afterward 4 hours moderate shaking at room T° -Add washing solution. -Add enhancement solution‚ and read the result.

Materials and Methods The laboratory procedures were conducted based on the steps provided in ‘An Introduction to Chemical Systems in the Laboratory’1. Specifically‚ 1.90 grams of KCL was weighed in a 250ml beaker and dissolved in 25 ml of deionized water. This solution was then quantitatively transferred to a 250ml volumetric flask. Proper technique is needed for quantitative analysis. This transfer was done to ensure that there was no detectable KCl left in the beaker. After transferring the

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

The purpose of this lab was to determine the concentration of NaCl or sodium chloride that is isotonic to elodea cells. First off‚ what is osmosis? Osmosis is this huge net of molecules moving through semi-permeable membrane to high concentration to direction where everything becomes balanced. This brings us to what osmolality is. Osmolality is related to osmosis and we know that osmosis has something to do with water so that being said‚ osmolality is number of osmoles of solute per liter in solution

and also to prepare slides for observable bacteria culture from yogart. Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides with 10x and 40x objctives lens. In each slide the differences was magnification and the 40x lans gave a clearer look of the specimen. The observation of slide e

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

EC 12/19‚ 2010 Forensics Period 5 Lab: Make your own Dental Impression I. Objective: The objective of the lab “Look and Record” was to identify the castings of your own teeth. The lab was also used to see how important forensic odontoloogy really is. What can a forensic odonotologist see in a dental impression cast that can help identify an individual? II. Background: Forensic odontology is important in all cases. Impressions can determine many things in a case.

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work
