LAB: Heats of Reactions, Calorimeters & Hess's Law
A lab that requires students to engineer and design their own calorimeter the experimentally test the heat of three different reactions (1. NaOH & HCl, 2. Zn & HCl, 3. Mg & HCl). The baseline design uses a thermometer, test tube, Styrofoam cup and water. Students are expected to engineer and design a more efficient calorimeter to more accurate capture heat. The lab also requires students to calculate the theoretical heat of reaction using Hess's Law to determine the percent error and a

Calculating Speed and Velocity Lab
Evaluate the relationship between speed and mass by racing weighted and unweighted hot wheel cars down an elevated meterstick. Each group of students will develop a hypothesis statement supporting whether adding weight to a hot wheel will increase or decrease its speed. Students will then measure the time it takes a hot wheel to travel down an elevated meterstick at different lengths. This experiment is then repeated with 5 washers stacked and wrapped to the hot wheel to increase the mass. Final
