Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

LAB REPORT HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3:

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

inhaled. You should see a white solid when the propanone has fully evaporated‚ this is crude paracetamol. We made sure we put it in a fume cupboard to ensure no evaporating fumes could escape from the propanone. It was left in a fume cupboard for a week after all the propanone had evaporated leaving behind crystals of pure paracetamol. Next you need to heat the crude paracetamol in a Thiele tube by filling the tube up with paraffin oil to the point where it just covers the entrance to the elbow tube

The first argument I chose from the essay states “It is unlikely‚ for example‚ that many Americans remember that‚ earlier in 2001‚ an earthquake in Gujarat‚ India‚ killed approximately 20‚000 people. One might explain the difference in reaction by saying that we naturally respond more strongly to the deaths of Americans closer to home than to those of others halfway around the world.” The premise of this argument is when the author states “It is unlikely‚ for example‚ that many Americans remember

A homeowner recorded the amount of electricity in kilowatt-hours (KWH) consumed in his house on each of 21 days. He also recorded the numbers of hours his air conditioner (AC) was turned on and the numbers of times his electric clothes dryer (DRYER) was operated. His objective was to relate the KWH consumption to the AC and DRYER usage. In addition‚ he wanted to know how many KWH’s the AC used per hour and the number of KWH’s used in each run of the DRYER.
