Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

the other factors will remain the same. A group of clock reactions will be used to determine the effect of concentration on reaction rate. The reactions include: 1.) NaHSO3 + H2SO4 H2SO3 + NaHSO4 *this reaction occurs quickly and is common to miss 2.) KIO3 + 3H2SO3 KI + 3H2SO4 3.) KIO3 + 3H2SO4 + 5KI 3K2SO4+3H20 +3I2 4.) I2 + H2SO3 + H20 H2SO4 + 2H + 2I 5.) I2 + starch starch I2 (blue-black color) Mathematically‚ we can use the Molarity formula to solve for the molarity of each solute

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:

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat

eroxide into water and oxygen gas. The students have formed a hypothesis toward this experiment. If the speed of decomposition of hydrogen peroxide is related to the temperature then in high temperature it will speeds the decomposition of hydrogen peroxide. Materials ● Catalase ● Hydrogen peroxide 3% and 1% ● Forceps ● Filter paper discs ● Water ● Ice ● Water baths ● Vials ● Marking Pencils ● Stopwatch Procedure 1. Set up an ice bath (0°C)‚ a room temp water bath‚ a 37°C bath and a boiling water bath

and Enzyme Concentration on Catalase Reaction Rate II. Introduction Enzymes are used to increase the rate of specific reactions in the body. Catalase‚ a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms‚ including chicken liver. The purpose of this experiment is to determine what changes in pH
