Abstract
We are learning about Metals and Nonmetals. We tested metals and nonmetals in the lab, to see if the metals and nonmetals will light up. But the metals only light up and nonmetals don't. Electrolytes gives us energy when we have a cold. We tested them, to see if they are metal or non-metals and the ones that were metals were the electrolytes. They play an important role in our body, because they give us energy.
Present Technology
Health practitioners prick our fingers and take a blood sample to see if we are low or high on electrolytes. Health practitioners do these kind of test because they want to make sure that we are healthy and so we don't have any problems in the future. Well there is a limitation of how much sweets you can have a day in your body system.
