Week 9 Week 9 Application: Diffusion of Responsibility Pro-Social Behavior Conceptually‚ pro-social behavior includes behavior intended to benefit others‚ including behaviors such as helping‚ comforting‚ sharing‚ cooperating‚ reassuring‚ defending‚ and showing concern (Fiske‚ 2012‚ pg. 342). Pro-social behavior is intended to help another individual or group‚ but not benefit the self. Pro-social behavior reflects four types of social motivation‚ which reflects our core social motives (Fiske

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

In this experiment‚ we had to demonstrate the process of osmosis using potatoes‚ and to determine the concentration of the cytoplasm of the potato. To demonstrate this‚ we had 6 test tubes and poured in different sucrose solutions of the following concentrations: 0.0M‚ 0.1M‚ 0.2M‚ 0.5M‚ and 1.0M. Once added in with all the sucrose solutions‚ we added in the 6 cylindrical potatoes of equal diameter and length. Before and after putting it in the potatoes‚ we had to weigh the initial and the final mass

Experiment 3: Evaluation of Gas Constant Purpose: The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab‚ the variables in the ideal gas law are known or can be found aside from the constant R. Thus‚ the R values can be found and relatively determine the relevancy of the ideal gas law to the lab conditions. The ideal gas law was tested using the reaction: Mg (s) + 2HCl2 (aq) H2 (g) Procedure: 1. Ribbons of magnesium (5) were cut to the approximate

Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

Experiment 8 “Lipids” and the purpose of the lab is to become familiar with the properties and reactions of certain lipids called fats or oil. For this lab‚ students are testing the properties and reactions of lipids and soap will be prepared and its properties will be tested. To begin the experiment‚ place 5 mls of water‚ ethyl alcohol‚ chloroform‚ and toluene in to four clean test tubes and add 1 drops of cottonseed oil to each test tube. Shake it and record your observation. To do part B‚ in three

Investigation - Osmosis in Potato Cells 9/7/04 Section 1 Planning Aim What is the aim of your experiment? What do you want to find out? The aim of this experiment is to investigate how potato tissue changes when placed in sucrose solution of different concentrations. Therefore‚ I want to find out if and how osmosis differs‚ when the concentration is changed. Variables What is the variable you are going to change in the experiment? The input variable of this experiment (i.e

Jessica Robins Lab 3: Properties of Organic Compounds Introduction Distillation is a physical process used to separate chemicals from a mixture by how easy they vaporize. The temperature rises unit it reaches the temperature of the lowest boiling substance in the mixture while the other contents of the mixture remain in their original phase (until the most volatile substance has all boiled off) as it’s heated. Hot vapor results and passes into a condenser and is then converted to a liquid

: Osmosis in Quail’s Eggs Research Question What is the effect of different concentrations of sodium Chloride (NaCl) on the mass of the de-shelled quail’s eggs? Introduction Osmosis is an example of passive transport. Osmosis is defined as the movement of water molecules‚ down its concentration gradient‚ from an area of high water concentration (low solute concentration) to an area of lower water concentration (high solute concentration) through a selectively permeable membrane. Osmosis doesn’t
