Biological Currency
Biological Currency The objective of this lab is to figure out whether or not this money is counterfeit. We will attempt to find the information needed to prove that the money is counterfeit or not by looking at it under a microscope and by using iodine drops to compare the money’s result with the results of different items. Counterfeiting money is not a new to any country. It started when paper money was first made. Some countries attempt to counterfeit rivals money to drive their economy downward. The Secret Service was made to prevent counterfeit money. Today counterfeiting money is still around but it is much more difficult to do today than it was 200 hundred years ago. I think that the money we are testing is real because I can

It would be counterfeit because paper has starch in it proving that the money is made up of paper. #2 The advantage of using the dissecting scope is that it has wide scope making your field of view bigger. The disadvantage is that you cannot increase your zoom very far. The advantage of using the light scope is that you can zoom in very far. The disadvantage is that your field of view is not big. The advantage of knowing your field of view is that you can compare to how much of the specimen you’re looking at. #3 The specimens under a light microscope must be thin so that light can pass through it without the light you cannot see anything. #4 Without staining material another way of making contrast between specimens is seeing how each affects to different lighting. #5 The resolution of the image goes downward as you increase magnification. My first hypothesis is supported through this lab because has been proven to be real. First, each of the facts about a real dollar match up with our dollar. Secondly, the color of the fibers matched up with color of the fibers in a real dollar. Thirdly, no starch was found in the dollar. I can infer now that money with starch in it is fake because real money does not have starch in it. There are sources of error in this experiment. Firstly, that money we used could have been stained affecting the color of the
