Calculators are needed daily in my classroom. When students are performing an energy lab where they have to deduce how much heat is given off in a chemical reaction by measuring temperature change, they use Q=m*c*t to figure out the amount of heat given off in a reaction. My students build airbags out of ziplock bags, vinegar, and baking soda. They can calculate how many moles of gas they need to fill their bag completely using the concept of stoichiometry and limiting reactants. In physical science, students build a roller coaster using a marble as the car. They calculate the amount of potential energy the marble has to begin with and then convert that to kinetic energy, and calculate its speed under ideal conditions. These are just a few of the examples that illustrate the high need for calculators in the classroom.
