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

this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess”

In “I Just Wanna Be Average”‚ Mike Rose tells the story of his high school experience and how his Stanford-Binet IQ test score got mixed up with another guy with the same Sir name; he was subsequently placed on a vocational track; which was the lowest class placement you could be assigned. We hear about a few of the classes he took over the four years‚ English‚ PE‚ Spanish‚ and Voc. Ed. Rose tells us about one teacher in particular‚ Mr. MacFarland‚ his senior year college prep English class‚ and

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 the particles

Introduction Cell respiration is the process of a cell converting sugars into ATP (energy) in the mitochondrion. It is an essential process which enables organisms to survive and function (Biology Online‚ 2010). Not only does it produce ATP‚ but also carbon dioxide (though decarboxylation)‚ NADH and FADH and in the case of some organisms‚ alcohol. Saccharomyces cerevisia‚ a bacterium commonly known as yeast‚ is used in various aspects of life‚ from winemaking to baking. It respires both anaerobically

The average number of hops to reach the sink node is shown in Figure [fig_M1]. In Sink-PathCC‚ the number of hops to reach the sink node does not change significantly with an increase on the node density. On the other hand‚ CoopSink increases the number of hops to reach the sink by over 40% when the number of nodes increases from 50 to 100. While Sink-PathCC demands for ≈7 hops to reach the sink‚ CoopSink requires nearly 17 hops when n = 100‚ an increase of nearly 142%. Clearly‚ Sink-PathCC provides
