Calorimetry Lab Problem: Which foods have the most calories? Hypothesis: If we burn the food then the heating released will be measured as calories because the energy stored inside is released as heat and light. Parts of the experiment Control Group-water Experimental Group- different foods Independent variable- Type of food Dependent Variable- temperature of water Controlled variables- water temperature of unheated water Materials Stirring Rod‚ Beaker‚ ring clamp‚ evaporating disk‚

sulphate solution Safety: 1. Be careful with copper (II) sulphate solution it is poisonous and corrosive. handle with care 2. Do NOT BREATH in any gases produced 3. If you touch any of the metals‚ you MUST wash your hands at the end of the lab Procedure: 1. Collect the materials and put on safety equipment. 2. Observe the metals and record your observations. 3. Into separate test tubes‚ place each metal inside. Label accordingly to metal. 4. Measure 5mL of the copper (II)

mass of the beans Dependent variable: the different types of beans Control: The beans Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent anyone from slipping. Materials Safety goggles

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the

Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

Rebecca Nov. 2013 Kyle‚ Mat‚ Alex Lab M7 Conservation of Momentum Abstract: This experiment involved the use of gliders on an air track which nearly isolates the colliding system from external forces to create low friction totally elastic and inelastic collisions. Seven different collisions were made‚ four elastic and three inelastic. The collisions consisted of only two gliders with varying masses and speeds. Each glider cart was equipped with a flag‚ and its passage through a photogate

The Osmosis Lab SHS Lacrosse Monster #2 Dates performed: 10/10/11 and 10/11/11 Introduction: The purpose of the laboratory investigation was to observe the diffusion of water across a semi-permeable membrane. In this lab‚ dialysis tubing was used to represent the semi-permeable cell membrane. Three dialysis tubes were prepared with 5% sucrose solution and were soaked in solutions of different concentrations. The diffusion of water across a semi-permeable membrane is called osmosis. When

PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the
