IntroductionAn organism has several ways to avoid being prated upon. One way to avoid this is to practice crptis. Crypis is the action of organisms avoiding predation by blending in with their backgrounds and matching the color pattern of a bark, twigs or leaves. Palatable animals often utilize this strategy as well. Another type of …

————————————————- INTERPRETATION OF RESULTS In the last experiment, relation between mass of an object or the net force with acceleration was defined. Another type of force acting on a system is to be discussed in this experiment. When two objects interact by touching or contacting each other, interaction is said to be subjected to contact …

Abstract In food industry such as the production of cheese, bacteria takes a significant role on the wide variety of cheese. Lactic acid bacteria(LAB), a bacteria that can be found in the production of cheese, its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The …

Think about it. Analyze it. Does the result make sense, based on the label and on what is known about the food. Do the results make sense to you. If they do not, think about, and research, what might be going on. Do not Judge, Just report (I. E. “The soda is bad because it …

B Physics Internal Assessment – Design Aspect 1: Focused problem: Investigate the relationship between the surface area of a circular hole and the time water takes to drain through it. Variables: Independent: Surface area of the hole Dependent: Time water takes to drain Fixed: Amount of Water Container Environmental Conditions Aspect 2: Control of the …

Ohm’s law and how they are part of an operation of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current, voltage and resistance as part of Ohm’s law. The second part consisted of how to use the variables in an electrical current. …

Vladimir Abstract A ball is tossed obliquely. The vectors of position and velocity are measured. The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore, in order to make the prediction accurate, how the horizontal and vertical components of a ball’s position as it …

In this practical, you will be assessed on Design, Data Processing & Presentation and Conclusion & Evaluation – Read the checklist of the criteria for guidance. Introduction: It is Saturday afternoon. You brew yourself a cup of coffee and are Just about to pour cold milk into the coffee. The doorbell rings and you realize …

Name: Fee Huh Date performed: November 12, 2014 Period 5 Teacher: Mr.. Glasses Purpose: The purpose of this lab was to solve problems that involve the vector addition. Introduction: My classmates and I were solving the equations by graphing them and/or to solve them algebraically. Each of the equations had scales and we were to …

This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Kennel’s Law …

Physics Lab Report How does the length of a string holding a pendulum affect its oscillation? Method 1. You will need the following apparatus: a pendulum, a piece of string, a clamp, a clamp stand and a timer. 2. Measure out CACM and attach the metal ball. 3. Establish an angle and let the ball …

Pendulum Jacob Lamer Group members: Josh, Courtney, Ashley Abstract: Determine the acceleration due to gravity using a pendulum. Introduction: A simple pendulum consists of a mass suspended by a length of string. When set Oscillating, the mass will have a period “T” given by the following equation. This equation shows the only variables that affect …

Uncertainty and Error Date Of Experiment : 1st October 2013 Course Name and Code : Physics Lab 1 (PAYOFF) Instructor’s name : Dry. Gaza Nick Safer Objective 1. To measure Human Reaction Time 2. To find uncertainty and error of a measurement Apparatus 1. Ruler Theory Human Reaction Time is a measure of how quickly …

So, the total work done is actually equal to the gravitational potential energy. In the result, it is obviously seen that high percentage error is calculated. It is because there are many ways of committing a mistake in this part. Some of these factors are assuring the angle and the height and applying an extremely …

Specific heat is defined as the amount of energy necessary to produce a temperature change of 1 co per gram of substance. The specific heats of different substances vary, and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimeter. In this lab activity, calorimeter will be …

Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall, that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size, shape, color, etc. Of the object if it would still …

Introduction In this experiment, we will investigate the relationship between the linear speed of an object and magnitude of centripetal force acting on it. We will use a stopper moving in a circle to create an upward force on the hanging mass; at equilibrium, the upward force on the mass will exactly equal the centripetal …

Also the total amount of energy in a closed system never changes. Along with my wonderful partner Kelvin e thought that energy in a closed system will remain constant throughout unless there is an outside energy such as “work” or friction. We also discussed the differences and similarities between closed and open systems. We wanted …

Purpose The purpose of this laboratory is three fold: 1. Familiarize the student with the concept and meaning of pH 2. Provide the student experience in measuring pH a. pH testing paper 3. Test the student’s hypothesis as it related to the pH of common solutions Hypothesis The pH of the tested solutions will be …

Lab Report Diffusion is One of two kinds of passive transport, Diffusion can transport ions from higher concentration to lower concentration region without any other forces. – A net movement of molecules in and out of cell membrane Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of …
