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‚

money on. Students should be developing independence while they still live with their parents so they know how it feels. If they learn how to be independent‚ they will know what to expect when going to college. They will be able to be an adult and know how it is to pay their own bills. They should be learning while they still have time. By being independent‚ they can find

Castelli Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

many subjective factors which are unpredictable and also non quantifiable. It is assumed that domestic economic fundamentals play determining role in the performance of stock market. However‚ in the globally integrated economy‚ domestic economic variables are also subject to change due to the policies adopted and expected to be adopted by other countries or some global events. The common external factors influencing the stock return would be stock prices in global economy‚ the interest rate and the

Reconstructing a Cow’s Knee Lab Objective: To learn the function of the knee and how its ligaments work to create the movement the knee makes by taking apart the knee and reconstructing it with different materials to replace the ligaments. Hypothesis: If we replace the cow’s knee tendons with rubber bands then it will work like a new knee because the rubber bands will provide the support‚ strength‚ and flexibility it needs. Safety: Wear gloves while handling the knee‚ use precaution when

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences
