Beet Lab By: Sumeet Grewal Purpose: The purpose of this lab was determining the effect of surface area on the beets ability to interact with the environment. Three similar sizes of beets were assigned. Each beat was cut up into different sizes as one large piece‚ two smaller pieces and eight tiny pieces. All three different slices of beets were placed in their own containers and tested. Observation: While the lab was going on‚ it was noticed the tiny pieces of beet were doing the best while the

Chart 3.1: Velocity at 3 degrees Chart 3.2: Velocity at 6.3 degrees Chart 3.3: Velocity at 8.5 degrees Chart 3.4: Velocity at 90 degrees Discussion: The results that were observed from this lab helped prove what was hypothesized. As chart 1.4‚ 2.4 and 3.4 displayed the object dropped off of the 90 degree slope was the quickest to cross 200cm‚ had the highest velocity and the highest acceleration. This was because at 90 degrees the gravitational

A. What is the name of the pigment that captures light? Chlorophyll B. Why does the pigment appear green? It absorbs other colors of light such as red and blue‚ so in a way the green light is reflected out since the pigment does not absorb it. 2. List two variables besides the wavelength (color) of light which might affect the rate of food production in plants. Light intensity and carbon dioxide 3. Why is chlorophyll important for all biological life? It is necessary for photosynthesis which

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

Ladies and Gentlemen The World Health Organization recognizes more than 200 primary immunodeficiency diseases (PIDD) - some are relatively common‚ others are quite rare; some affect a single cell within the immune system; others may affect one or more components of the system. An accurate medical history‚ family history and physical examination are critical in developing the best strategy for laboratory evaluation‚ and the orderly use of laboratory testing is strongly recommended. This typically

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

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Through Dialysis Tubing (a Semi-Permeable Membrane) I. DESIGN A. PROBLEM/RESEARCH QUESTION 1. How does increasing molarity of sucrose affect osmosis through dialysis tubing? B. VARIABLES 1. The independent variable in this lab is the molarity of sucrose each dialysis bag is filled with. The time (30 minutes)‚ the temperature (23C) and the type of dialysis tubing used are all constants. 2. The dependent variable is the final mass of the dialysis bag. 3
