Introduction

Glucose Coursework Introduction: In this experiment we will be testing fluids for glucose because a body fluid sample is detected at a scene of a crime and a sample taken using a cotton bud. The prime suspect is a diabetic so that is the reason why we are testing for glucose. Planning: The person who is the suspect is a diabetic. So a test using Benedict's solution will be used for reducing glucose. There will be two tests. One of the tests will be using glucose mixed with glucose and the other test will be with a sample of body solution mixed with glucose. The sample of body solution will replace the Benedict's solution. Safety Points: There are not really any safety points in this experiment because none of the materials used in this experiment were dangerous. You just had to make sure that you didn't burn yourself when the Bunsen burner was on and let the test tubes and the tripod cool down before touching them and taking them out of the beaker. ...read more.

7. We put in two test tubes into the beaker but the other test tube did not contain any benedict's solution it contained a sample of the body fluid. We did the mixing of the glucose/sample of the body fluid and the sugars at the same in two separate test tubes. We put them into the beaker at the same time and we watched the solutions that were in the test tubes change colour. Results: The Benedict's solution and the sample of the body fluids were in different test tubes and they both went through a series of colour changes from blue to green to yellow to orange to red/brown. Conclusion: When you are reducing sugars such as glucose then it gives you a red precipitate of copper oxide. When we did the test on glucose it turned from blue to green to yellow to orange and then red. Evaluation: This test was a good experiment and it was quite easy. ...read more.

Conclusion

If we had used a test tube we would first weight it and know how much it weighed then put 1 gram of glucose into the test tube and then we would not have to tip any of the glucose out because it is in the test tube where we want it to be. Discussion of Vocational Implications: If a forensic scientist was actually carrying out these tests on a prime suspect who is a diabetic then he would use a volumetric flask first of all to get a set of correct results and he would measure of the glucose better than what we did in out experiment. If the scientist really wanted to know who the suspect was then he would probably repeat this experiment so that he will get the right results. He would also do this so that he would know if he has got the results wrong or anything. Naman Rafique 10g ...read more.
