Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

insects‚ fish and worm. These animals rely on the outside environment for their body heat as they do not generate heat internally like a mammal or bird. Ectotherms have a variety of adaptations‚ many of them behavioural‚ to regulate their body temperature and keep it within the range in which they can be active; 10-30oC The Tiliqua or more commonly known as the blue-tongue lizard or just Blue tongue is the largest member of the skink family in Australia. There are six species of blue-tongued lizards

Planaria Regeneration in Ideal Temperatures vs. Cold Temperatures Christina Malfas Abstract Planaria are flatworms that live in quiet freshwater bodies. They live in a narrow range of temperatures‚ from 22-24°C. They regenerate asexually‚ specifically through a process called epimorphosis‚ in which they completely regenerate one half of their bodies after splitting themselves in two. The diffusion gradient model assumes that cells in an organism “know” their orientation on that organism due

The height difference that is used in the experiment varies from 0.5m. It adds by 0.5m in every drop height. A trend line showed on the graph and explains that the higher the drop height the higher the ball bounces back. When the height the ball bounces back is rounded the pattern of increasing the bounce height is by 0.2 m as shown‚ 0.7‚ 0.9‚ 1.0. The pattern of the bounce height explains this when the numbers are rounded. In each increasing drop height‚ the amount of m that the ball has bounced

The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

Chapter 6 Measuring Vital Signs Unit 1: Temperature‚ Pulse‚ and Respiration UNIT RATIONALE Important indicators of your patient’s/client’s health status are known as vital signs. Vital signs give you information about breathing‚ body temperature‚ and the heart. They are a good indication of how well the body systems are functioning. As a health care worker‚ you need to observe patients whenever you are near them. Your knowledge of vital signs and how to measure them helps you know when to report

The Question: Does temperature affect the elasticity of a rubber band? Our Hypothesis: We thought that in hot water that it will be the most elastic. Simply because hot water make things stretchy and moveable like balsa wood. Material: 1. Three Cups 2. Nine rubber bands (should be the same) 3. Cold Water 4. Hot Water 5. Room Temperature Water 6. Two pencils (you will see why later) 7. Four Ice Cubes 8. Water that is sitting in an indoor location 9. Stop Watch 10. Ruler Experimental 1. Take one cup
