and soda are not helping improve our schools as promised. Our schools still look the same with no support‚ extra-curricular activities. The tax didn’t change anything for our schools. Our books still old and falling apart. People from Pepsi quit their job because they thought they weren’t getting paid enough. The soda tax should affect their paycheck. This is really an outrage and it is affecting not only the jobs at Pepsi Co. also it is effecting the stores who are not selling as much sodas and

Mike Morrison – SCH3U Types of Chemical Reactions Lab Intro/Purpose The purpose of this lab is to determine types of reactions with only the reactants and through observation. Through observing the experiments‚ one is able to see a visual of each type of reaction taking place and it gives them a better understanding of how chemical reactions work and what products they may form. Materials & Procedure Materials: * Wood Splints - Copper Sulfate * Sodium Sulfate - Copper

The Lemon Orchard character analysis The Lemon Orchard by La Guma expresses the clashes of the characters personalities throughout the short story. The main characters that are shown within the story are the African man‚ the leader‚ the man who was carrying the lantern‚ and two other men that followed. The leader of the group is presented to be the most dominant compared to the other men. ’He was a big man and wore khaki trousers and laced-up riding boots‚ and an old shooting jacket with leather

SODA AND MENTOS Physical Science (3rd block) Mythbusters Project Introduction This experiment is to prove the theory that when Mentos is dropped into a bottle of soda the end result is a huge fountain spray of soda from the bottle due to a process called nucleation. Hypothesis If I drop Mentos candy into a bottle of soda‚ then it will create a huge fountain splash. Materials *Regular Mentos Candy (one)

Chemical Reactions Lab Introduction Four different types of chemical reactions were observed in this lab. Synthesis reactions occur when two different elements or compounds form a more complex compound as shown by equation (1). Single replacement occurs when one element replaces another to form a new compound as shown in equation (2). Double replacement occurs when two different atoms in different compounds trade places with one another to form two new compounds as shown in equation (3).Combustion
