Find Glucose educational ideas and activities
Within the setting of a crime scene investigation, biochemistry beginners analyze organic compounds as a means of determining "Who dunnit." They use a brown paper test for lipids, glucose test strips and iodine to identify carbohydrates, and Biuret reagent for proteins. They apply what they experience to the lunch remains of the suspects in order to solve the mystery of who stole Jerell's iPod. The procedures, data tables, and evaluation questions are well-written, making this an A+ activity.
Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively permeable membrane into the water. This classic experiment is laid out in a way that keeps biologists on target and engaged in the learning experience. Photos and diagrams help make the concepts clear.
Begin the lesson by having your class write what they know about diabetes. They learn through a skit how the body metabolizes glucose. A visual representation of the two types of diabetes is displayed, and then learners participate in role-playing patients with diabetes and their doctors. Handouts and teachers notes are provided. The link to the skit does not work, but the skit is easily located via an online search. It's not an exciting lesson, but it is educational and pertinent, especially with the epidemic levels of diabetes in the Western culture. A few of the student research links are broken, but the majority do work.
This could be really good, or it could be really bad! The crime to be solved is, "Who went pee in the flowerpot?" Given four imitation urine samples, young chemists or crime scene investigators perform pH, glucose, and turbidity tests to uncover the perpetrator. Whereas this is a sound lesson in making observations, if you have any students with the same name as the boys in the story, you may want to change them to minimize excessive laughter!
Sal utilizes a problem from a chemistry textbook in order to shed light on the process called Stoichiometry. This is an extremely long video and is heavy on the math. The problem that Sal works through illustrates the techniques involved in finding the masses or carbon dioxide and water that are formed during a reaction between glucose and oxygen.
Use this video to explain how Diabetes affects insulin production. Processing glucose is the main concept explained in this resource. It gives valuable details about the regular, pre, and post-meal normal levels of blood sugar concentration, and how they are affected over time by the different levels of insulin generated in diabetics.
If your students need more information about diabetes measurements, this video will be very useful. Sal explains the correlation between glucose and hemoglobin and resulting bonds that affect the levels of Hemoglobin AC1 (hemoglobin AC1) in the blood. By explaining how rates of AC1 formation are affected, Sal is able to demonstrate that doctors can estimate a measure of glucose over time.
Students decompose glucose and write an equation for the reaction. For this decomposition reaction lesson plan, students burn a sample of glucose and test the products for water using cobalt chloride paper. They write a balanced equation for the decomposition of glucose and answer 3 analysis questions.
Students test for organic molecules to determine if a solution contains once living molecules. In this characteristics of life lesson, students test common liquids for the presence of organic molecules, including starch, protein, and glucose. Based on the results of the test, students determine if the liquid contains molecules that were once in living things.
High schoolers experiment with lactase to find out how milk sugar is broken down in the body. In this enzyme lesson, students use glucose strips to investigate the breakdown of lactose into glucose and galactose for milk digestion in the human body. They use lactase enzyme to simulate the process.
