1. Temperature: Put some hot water‚ warm water‚ and cold water in three bowls. Just use water from your faucet‚ and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds‚ place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water‚ my finger felt a hot

Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because dry soil contains little moisture

Factors affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.

Introduction I am require to review a play activity that I used my observational skills to plan for. I decided to do indoor art activity‚ which was making a Robin. Children by doing this activity may learn the textures and colours‚ and they will use a hand and eye co-ordination. The Intellectual‚ Physical‚ Language‚ social and emotional observations allows the adult to find out what children understand‚ how they think‚ what they are able to do‚ and interests are. This information helps the adult

Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

completely separate genres. I also find it hard to categorize a band into one specific genre. So many bands have so many songs that could be put into a different category. So while Johnny Cash could be a country artists or rockabilly‚ and even in some of his more recent covers‚ I would see him as a rock musician. Folk rock brought the always-classic Bob Dylan‚ Sonny and Cher‚ and Simon and Garfunkel. Further down the line I would lump bands like the Eagles‚ Lynard Skynard‚ Alabama and Little Feat. It

extramarital sexual partners make it more likely that men will bring HIV into the union after marriage. According to Asunta Wagura‚ Executive Director Kenya Network of Women Living with AIDS‚ There are several reasons married women and girls are at increased risk of HIV/AIDS‚ including; They often are powerless in decisions to have sex or use a condom‚ Women who are married and faithful to their husbands are at risk of HIV infection because their husband move on with other women who may be infected with

ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing surface area increases the reaction rate‚ and increasing temperature also increases the reaction rate. Temperature is the measure of the average kinetic energy of

Do human activities damage our planet‚ or do they make it a better place to live in? Our planet has being threatened by human activities approximately since the Industrial Revolution‚ in the 19th century‚ which has contributed to expand the greenhouse effect. From this time on‚ humanity has massively increased the gases that are sent to the atmosphere due to better life conditions‚ allowing people‚ from all over the world‚ to use certain new objects and energies that damage the suitability of
