In Section 3, the proposed methodology is described while the results are presented in Section 4.
Aug 26, 2019 This activity is an inquiry based lab where students investigate and discover how surface area, concentration, and temperature affect the rate of a chemical reaction. Students will be asked to find 3 factors that change the rate of the chemical reaction involving hydrochloric acid and alka-seltzer.
Oct 30, 2019 In this simulation, students will have the opportunity to investigate several factors that can affect the initial rate of a chemical reaction. Students will have the opportunity to manipulate several variables including concentration, temperature, or surface area of the reactants as well as the addition of a catalyst during the simulation.
Nov 11, 2016 Hazards Tripping Shocks Slipping Concussion Elodea Results My results prove my original hypothesis to be correct When the distance from the light source and the pondweed increased the rate of oxygen production decreases, therefore the more higher the light intensity the greater
