1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill

higher resolution and more light‚ you need to put more than one mirror together and make them work together‚” explains Robert Angel‚ a professor of astrology at the University of Arizona (Giant Mirrors to Capture the Universe). Just as we learned in our lab‚ we need a good source of light for something to become clear. The mirrors that are used for the telescope cause the light to be reflected off of one mirror onto the other which then create a clear image from the large convex lens. “Because these

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

Potato osmosis report Operators Introduction The purpose of the liberation Liberation is to understand what is happening with the potatoes when it is in the water. To find out how osmosis takes place and what it ’s purpose as well as other examples of osmosis. The experiment is to understand what is happening with the potatoes when they are in the water and understand the osmosis process occurs. Osmosis Background facts Osmosis comes from the Greek "[-mo: ´ s] (new latin osmo ´ sis‚ Greek

Demonstrating osmosis Introduction The movement of water in and out of a system bounded by a membrane permeable to water‚ but not certain other substances‚ can be inferred by either mass changes or volume changes in that system. It is possible to monitor other changes in physical conditions‚ such as texture. Monitoring mass enables quantification of the changes‚ whereas other changes may only be qualitatively measured.
