    Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

    designed to study the effect of exercise on skin temperature and heart rate. Studying the effect of exercise on skin temperature and heart rate yields understanding of how homeostasis is achieved in humans. This knowledge creates opportunity to discover more effective ways to return the human body to optimal functioning‚ rather than a reliance on natural processes. This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals of intense exercise

    In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray

    Defining the problem and selecting variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one

    The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

    ≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

    and Heart Rate Prelab Questions: 1.) If the peripheral blood vessels were constricted without making any other further adjustments in the cardiovascular system then the blood vessels could potentially burst due to the built up pressure and no further decrease in heart rate. The vessels would be smaller due to the constriction but the heart would continue to pump the blood with the same or greater force. The dive response prevents this from happening because it lowers the heart rate so that

    Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

    : As you can see that the greater the amount of pennies were added at the top of the cup‚ the shorter the distance of the cup moved and it included all of the three Newton’s laws. My hypothesis actually turned out to be accurate. It’s really fascinating that how only 1 experiment can prove all of Newton’s three laws of motion just like that. When the marble was getting released from the ramp I observed it hitting the cup and surprisingly the cup didn’t fall off or changed directions it went in
