Diffusion In Agar Cubes Is Bigger Better? OR Is Smaller Smarter? Adapted from Flinn Scientific Publication No. 10110 Introduction: Diffusion is one of the very important processes by which substances such as nutrients‚ water‚ oxygen‚ and cellular wasted are transported between living cells and their environment. This activity will help you explore the relationship between diffusion and cell size by experimenting with model “cells.” In this experiment‚ you will use agar cubes to which the

Best Rubik’s Cube I know what you’re thinking… “Are there different kinds of Rubik’s Cube?” The answer to that question is a resounding YES! There is a variety of Rubik’s Cube of different sizes. Apart from the usual 3 x 3 x 3 Rubik’s Cube‚ there’s a 2 x 2 x 2‚ 4 x 4 x 4‚ 5x 5 x 5‚ 6 x 6 x 6‚ 7 x 7 x 7 Rubik’s Cube as well. Heck‚ there’s even a pyramid and dodecahedron shaped Rubik’s Cube. However‚ if you can’t solve the regular Rubik’s cube‚ you might have a headache trying to solve the other Rubik’s

Diffusion and Osmosis Introduction Tonicity refers to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic‚ hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A‚ Solution B‚ Solution C‚ and Solution D. Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl. In other

nDescribing food Describing food is not as easy as it would seem. How many ways can you say something was really tasty? Not enough to keep you interested in what you are writing. That is why we have to borrow words from other areas to describe the food and the effect it has on us. You can compare a dish to a picture‚ a sports game‚ a musical performance or give it personality. Describe its sunny or somber mood‚ shyness‚ assertiveness‚ or contradiction of flavors. Knowing the words for describing tastes and

Introduction The purpose of the experiment was to determine the melting points of compounds using a Mel-Temp device. The melting point of naphthalene‚ urea‚ and sulfanilamide are found. This is then followed by the measuring of an unknown compound‚ and an impure sample (a small amount of naphthalene mixed with the unknown). Experiment In the lab‚ the height of the chemical in the capillary was set to 2-3 mm thickness. The voltage at the Mel-Temp started at a low setting of 1.5-2. The heat was

The Melting Pot Is The United States of America the “melting pot” of the world? A melting pot is “a place where races‚ theories‚ etc.‚ are mixed.” (The Oxford Dictionary) Many immigrants come to the United States for the same basic reason: A better way of life. These same immigrants envision their dreams of success‚ freedom and happiness coming true. Without different cultures coming together learning from one another‚ many of today’s modern marvels would not exist. A good example of this is
