between a food label and and the amount we measure in a lab. For this lab‚ we will be experimentally measuring how many calories are in different types of food. Before we begin the lab however‚ we need to investigate the science behind it. Firstly‚ we need to figure out if this project is even possible. Luna Abdallah et al created an experiment making it possible. To measure the amount of calories in a food‚ you first have to light it on fire. Your homemade calorimeter will trap the heat of the food and

Purpose: The purpose of this lab is to identify the presence of cations and anions in four unknown solutions by identifying whether they are copper‚ silver‚ iron‚ or chloride ions which is done by adding sodium hydroxide‚ solid copper‚ silver nitrate‚ and potassium thiocyanate to the solutions and analyzing the chemical reactions. Introduction: Chemical change‚ unlike physical change is the change in the composition of a substance rather than simply its shape‚ size‚ or state (Marie‚ 2015). Signs

term “Food Security” originated in 1960’s and 1970’s. Public interest in global and domestic food security grew between the years 1972-74. Food Security means that all the people at all times have physical‚ economic and adequate amount of nutrition required to them.Food Security is one of the major problems related to nutritional status. It also means that people who produce food are also able to earn a decent living‚ have good surroundings‚ well and a proper diet. A person is called as food secure

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently
