In the year of 2000‚ Santa Fe Independent School District approved a policy that would allow a student to give a prayer‚ which the district referred to as messages‚ at Friday night football games. These prayers were student initiated and were given through the public address system at the Santa Fe High School stadium. These prayers or ‘messages’ were given because students from the high school voted in favor of these student led messages. The practicing of giving these messages would violate the

How does the amount of dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte

Experiment1Separation of mixtures by filtration and crystallisationBackgroundThe separation of a mixture of two solids can often be achieved by filtration and crystallisation. To be successful‚ this requires that the components of the mixture have different solubilities in a particular solvent. AimThe purpose of this experiment is to separate sodium chloride/charcoal and sodium chloride/copper(II) chloride mixtures.

blue‚ green‚ red‚ and yellow mixtures inside the test tube. Before we even put in the orange solution‚ the yellow liquid started to mix in with the red solution. It meant that the yellow sugar water was more dense than the red sugar water. On our second trial‚ we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube‚ we decided to experiment and put in the yellow solution. The second we put the yellow mixture in‚ it immediately mixed in with
