The junior chemistry class have been learning about moles, and not the ones with hair!

On Jan. 27, various tasks were conducted and the students were able to find the unit of weight using the mole equation (6.02 x 10^23). “Mole” helps in finding the weight of very small objects or amounts of elements/chemical bonds. The class particularly enjoyed learning how much chalk is used in order to write their name on a piece of paper. Through summing the different element’s mass in chalk (CaCO3)-this can be found using the periodic table- they were able to find how many grams are in one mole of chalk: 100. Using this number, they multiplied it with the equation for a mole, and then moved the decimal placing over. The class looks forward to more of Mrs. Schumacher’s hands on activities and fun classwork!
