ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

Procedure: 1. Gather All Materials 2. Place the bunny turned in on itself on the ground (this enables the toy to launch itself upward by suction; elastic and potential energy). Do so 5 times 3. Measure the height traveled by the stopper using a meter stick per each trial. 4. Using the measurements

Scientific Investigation: Designing an Experiment Jeremy Barrett BIO-101-C02 February 4‚ 2015 Introduction Different parts of the body of an organism have been observed to grow at different rates during development. When parts of the body grow disproportionately to one-another‚ we call it allometric growth. The term‚ isometric growth‚ is used when describing body parts which maintain the same ratio throughout development. The purpose of this experiment is to determine whether two chosen body parts

Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel‚ which leaves a clean test tube. Incomplete

Chemestry Lab Rates of Reaction (Picture from: http://sciencespot.net/Pages/kdzchem.html) The rate of reaction is how fast or slow a reaction is completed. This is important for factories and chemists all over the world. What happenes during a reaction is atoms or molecules that collide and form new molecules. You can affect this rate of reaction with: temperature of reactants or suroundings‚ surface area of reactants‚ if there is a catalyst present‚ but in theis lab the concentration was changed
