8.01 Lab Report FLVS The purpose of this hands-on lab is to model the concept of half-life using a sample to represent radioactive atoms. Materials 200 M&M® candies‚ pennies‚ or other small candy/item with two distinct sides shoe box or other small box with a lid Procedure 1. Place 200 candies in the shoe box‚ lettered sides up. The candies will stand for atoms of a hypothetical radioactive element. 2. Cover the box and shake it vigorously for three seconds. This is one time interval.

The 7 Deadly Sins and 7 Cardinal Virtues ======================================== Overview -------- The "Seven Deadly Sins"’‚ also known as the "Capital Vices" or "Cardinal Sins"‚ are a classification of vices that were originally used in early Christian teachings to educate and instruct followers concerning (immoral) fallen man’s tendency to sin. The Roman Catholic Church divided sin into two principal categories: "venial"‚ which are relatively minor‚ and could be forgiven through any sacrament

Practical 1- An experiment to observe the features of an Onion Cells Method: Gather all equipment that will be used for the experiment and check that they are clean and undamaged. Using forceps‚ peel the membrane from the underside of a small piece of onion. Place the membrane flat on a clean‚ glass slide and add one drop of iodine solution. Use a pin to carefully lower the cover slip over the slide‚ ensure there are no air bubbles before the use of the slide. Set the microscope to its lowest

Taylor Hill Lab 6: Enzymes Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide‚ a household blender‚ potatoes (3 medium size potatoes‚ that are peeled and quartered)‚ tap water‚ 8 test tubes‚ 8 transfer pipets‚ sugar packets‚ salt‚ a small saucepan‚ a refrigerator with a freezer‚ stove

The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material‚ which allows some things to pass through them but prevent other things from passing through. The cells allow small molecules like Oxygen‚ water‚ Carbon Dioxide‚ Ammonia. But will not allow larger molecules like Sucrose‚ Starch‚ or protein‚ etc

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different
