In the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.
The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.
LABORATORY REPORT Activity: Enzyme Activity Name: Natalie Banc Instructor: Elizabeth Kraske Date: 09.26.2016 Predictions 1. Sucrase will have the greatest activity at pH 6 2. Sucrase will have the greatest activity at 50 °C (122 °F) 3.
It was hypothesized that the optimal pH for the enzyme was pH 7 while the 1.0 ml peroxidase would have the best reaction rate. At the end of the experiment the results prove the hypothesis to be incorrect. INTRODUCTION Enzymes are proteins that allow a reaction to speed up. These proteins are made up of monomers known as amino acids.
In the control, beta-amylase was present unlike the experiment, which resulted in less molecules lingering. Discussion: 1. a. My results matched my prediction regarding alcohol percentage by weight.

Description: During this activity the children will be provided an anger meter. This meter will be drawn on construction paper, numbered one threw five exspressing different anger emotions. Behind each emotion, there will be a flap giving a solution. This meter will also give the children a chance to react to each emotion. It will teach them to comtrol their emotions as well as handle their disappointments.
The Study of Diffusion and Osmosis Using Deshelled Eggs Maquita A. Dieufene Jessica Thelwell(Partner) 10/09/2014 1611 Evening Lab Introduction It is quite simple to overlook the roles diffusion and osmosis play in daily life. If one has ever spent too much time in the pool and watched as their fingers begin to turn prune-like, that is an example of osmosis. Osmosis is simply defined as the movement of a concentrated solvent through a semi permeable membrane to a more concentrated solvent.(Biology Corner) Relating to the earlier example of osmosis, your body acts as the more concentrated solvent for the water to penetrate. Diffusion is the exact opposite of osmosis.
Starch solution is then placed into the test tube at a quantity of 5 mL. 5 drops of Lugol’s Iodine solution is added to the test tube. If the color changes, then it is known that starches are present in the solution. Proteins are next tested. In order to do this, 5 mL of gelatin solution is added to the test tube. 10 drops of Biuret’s reagent are added to test for protein.
CHAPTER 11. HOT SPOTS, CPTED, & SCP Routine Activities Theory Different lifestyles equate to different risks of being victimized (Vold et al., 2002). The spatial and temporal characteristics of each person’s normal, legal, and daily activities, known as routine activities, affect the amount and type of illegal activities that the person is exposed to in certain areas (Akers and Sellers, 2009; Cohen and Felson, 2004). For example, if there are a lot of people congregated in a certain spot, such as inside a home, that spot will be less attractive to criminals.
5 water bath were set up each to10 °C. (5 were used do the experiment faster) 5 cm3 of starch solution were added into the 5 test tubes that were labeled test tubes. Then 5 cm3 of amylase enzyme was added into the other 5 test tubes that were labeled. Put one of the starch solution test tube (preferably the one labeled 1) and one of the test tube containing amylase into the water bath (10 °C).
Classrooms that have well-defined activity areas encourage children to become more involved in developmentally appropriate activities and to explore more. Well-defined activity areas are designed for about 2-5 kids. • Have resources appropriate for the activity and in sufficient amount for the number of children. • Are partially surrounded by walls or low partitions. • Have bookcases, storage cabinets, or other furniture as partial dividers and can be moved and changed as the teachers or children wish to create different activity groupings.
Analysis of Reports The Course Activity Overview was the first report that I analyzed for this activity. The course overview initially displayed a bar graph of all enrolled user’s activity by day within the course shell for a duration of two weeks (July 21 through August 4); hours spent was labeled on the y-axis and the days of the week was labeled on the x-axis.
Activity Description and Summary For this activity I was responsible for performing a teacher evaluation. I conducted the evaluation on Carol who is one of our middle school math teachers. She has been a long time aid and switched over to being a classroom teacher a year ago.
There are many different schools of criminological theories that all attempt in explaining crime in different ways. Among these various school of thought are the environmental theories, which do not focus on the individual or even groups of individuals, but instead focus on the environment itself and whether or not it is likely to contribute to criminal activity. One particular environmental theory, Cohen and Felson’s Routine Activity Theory, states that “…in order for a crime to occur, motivated offenders must converge with suitable targets in the absence of capable guardians…” (Cohen, Agnew, & Wilcox 2014). If one of those three components is missing, then the theory argues the lack of a motivated offender, a suitable target, or if there
