LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

Lab Report: Stoichiometry Lab Oct. 27‚ 2011 Claire Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

Hormone Control of Leaf Abscission Lab Report February 24‚ 2011 By Patrick Mills Introduction- Hormones are a chemical are transported within an organism and are highly specific chemical signals between cells. The hormones we used were lanolin‚ auxins(IAA)‚ cytokinins(CYT)‚ ethylene(ETH)‚ and gibberellins(GA) and each has a different purpose. Auxins will control cell elongation‚ cytokinins promote the act of cell division‚ ethylene causes the ripening of fruit‚ and gibberellins will elongate

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether
