this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the

variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one being that your muscles require
