Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Arianna Montoya Osmosis and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

Botany Lab ------------------------------------------------- Introduction This study observed the effects of different body fluids and solutions relative to breaking down bacteria‚ specifically in the human body. The enzymes we studied‚ lysozomes‚ help the body lyse‚ or break down bacteria by targeting peptidoglycan in bacterial walls. The solutions and fluids studied were saliva‚ mucus‚ tears‚ a stock solution of lysozomes‚ and distilled water. The solutions were placed in agar containing Micrococcus

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

Observation of Planarian Abstract: The objective of this lab report is to report our findings on the planarian. We extracted the planarian from a beaker and observed them under a microscope. We observed its sensitivity to touch on different parts of its body‚ its sensitivity to talcum powder‚ its reaction to a small piece of liver‚ and its sensitivity to light. Introduction: The problem we are investigating is how sensitive it is to touch on different parts of its body‚ its sensitivity to
