in Pipet 1 Thymol Blue Indicator‚ 0.04% - 0.5 mL in Pipet Experiment procedure: Part I: 1. Prepare an ice water bath by partially filling one of the 50-mL beakers from your LabPaq with tap water and crushed ice. Set aside. 2. Prepare a hot water bath by partially filling the second 50-mL beakers from your LabPaq with very hot tap water. Set aside. 3. Using a 24-well plate add 5 drops of 2.0 M MgCl2‚ magnesium chloride solution to wells C1 and C2. Add 10 drops to wells C3 and C4. 4. Add

brain neurotransmitter. | Follicle stimulating hormone (FSH) | The pituitary secretes FSH. It stimulates the sex hormone estrogen and development of follicles in the ovaries. And Sperm production in the testes. | Growth hormone (GH) | GH promotes mitosis and cellular differentiation. GH does not have specificity like other hormones. | Luteinizing hormone (LH) | LH stimulates ovulation of eggs from the follicles developed by FSH in women. In males LH stimulates the testes to produce testosterone

by heating/burning a portion of the food item and catching the heat released into a known mass of water in a calorimeter. We will also identify units of measuring heat such as calories and joules. We will use basic lab equipment provided in our labpaq and we will use several household items as well. We will follow all safety requirements and standard procedures for this lab. We learned from the chapter that a “calorie: is a unit of energy‚ just like a kilowatt-hour or a joule. These units

C. How would you explain a sand recovery percentage that is higher than the original sand percentage? D. What were potential sources of error in this experiment? A.) The methods I proposed were highly similar to the instructions used in the labpaq manual. Just as stated in the instructions‚ I would have used the magnet to separate iron fillings‚ but I would have thought lastly upon

Report Submitted: September 4‚ 2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # |

Mini-Lab Report Objectives: There were two major goals of the “Observing Bacteria and Blood” experiment. The first was to establish a familiarity with the proper techniques for using a microscope. The experiment focused on both the basic components of a microscope (i.e. how to adjust the knobs and levers for the desired result) as well as how do decide the proper objective to use for observing a specimen. The second goal major goal of this experiment was to practice observing live specimens
