Product Description
In this short activity, students will practice their skills of molar conversions to calculate the quantity of grams, moles, and atoms of graphite used to write with in their pencils. Students will be asked to compose a letter or drawing to give to a friend in the classroom (all creations must be school appropriate) on a provided sheet of lined paper. Students will determine the mass of the blank sheet of paper and then the mass of the same sheet of paper containing their letter/drawing to a friend. (Please relay to students that they must ensure that all pencil markings are dark/thick and that the majority of both sides of the paper must be filled. Little white space should be visible for best results.) Once students have subtracted the mass of the blank sheet of paper from the mass of the paper with graphite writing, students will use both the molar mass of carbon and Avogadro's number to calculate the number of moles and atoms used to write. Students are astonished at the end of this activity at just how many atoms of graphite they used to compose their creations and how small an atom really must be!
