they are cold blooded and the cold weather makes them slower. Being cold blooded‚ means that it adapts to the climate more as the temperature changes. Experimental Design The controlled group is the group where all the mealworms where at room temperature. The experimental variable was that we needed warm water and ice. The experimental set-up was that we made a hot and cold climate for the mealworms. For the hot climate the temperature kept rising and the cold climate went down

Experimental Errors and Uncertainty No physical quantity can be measured with perfect certainty; there are always errors in any measurement. This means that if we measure some quantity and‚ then‚ repeat the measurement‚ we will almost certainly measure a different value the second time. How‚ then‚ can we know the “true” value of a physical quantity? The short answer is that we can’t. However‚ as we take greater care in our measurements and apply ever more refined experimental methods‚ we can reduce

graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second part of the prediction

from an irregular solid. We use the Water Displacement method to get the Volume of an irregular solid whereas in a regular solid‚ we only multiply the length‚ width‚ and thickness of the solid. Percentage Error is the absolute value of the difference of the Theoretical value and Experimental value all over the Theoretical Value multiplied to 100. It is used to compare the results obtained to the known or accepted value. METHODOLOGY I. Materials 50-mL graduated cylinder 125-mL flask Electronic

The Uniqueness of Experimental Research * Experimental research is unique in that it is the only type of research that directly attempts to influence a particular variable‚ and it is the only type that‚ when used properly‚ can really test hypotheses about cause-and-effect relationships. Experimental designs are some of the strongest available for educational researchers to use in determining cause and effect. Essential Characteristics of Experimental Research * Experiments differ from other

Lab Report The effect of temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase

Experimental and Non-Experimental Research Designs. Evaluating a Survey Student’s Name Institution Research can either be experimental or no-experimental. Between the two research methods‚ experimental research is the most scientifically and also the most sophisticated research method. This makes the experimental be defined as observation that is under controlled conditions. Experimental research design method is concerned with examination of the effect of independent variable on
