    group of protein and protein can break easily by acid, base, and hot temperature. To experiment our question, we used catalase solution, 3% H2O2 solution, 0.1 M HCl solution, 0.1 M NaOH solution, a beaker, an O2 gas sensor, sensor interface on a Chromebook, pH paper, and safety gloves. Therefore, we conducted experiments to test how enzyme activity in different conditions. Plus, we predicted that if temperature increases or enzyme have contacts with acid or base, enzyme activity will decrease. We

    Determining the pH of Household Items March 22, 2016: Sara, Sam Introduction: Everyday household items can be seen as just “household items”. However, it is often not realized that we could actually determine the pH very easily. It could also be important to know the pH in everyday life. For example, it is important to keep track of human pH levels. Some people are curious to see the pH of their own body, which is a great use to keep acidic levels leveled. Another use in real life is determining

    Question: Does the depth of the river affect its overall pH from mid december 2015- to early january 2016? Knowledge Probe: According to.epa.gov/acidrain/measure/pH.html, pH is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH. A pH of 7 is the most neutral you can get and 0 being the most acidic and 14 being the most basic. each level is 10 times more basic/
