Every year the high school chemistry classes celebrate National Chemistry Week, which also coincides with National Mole Day. Mole Day is October 23 – the reason for the date is that there are 6.02 X 1023 particles in one mole (similar to how a dozen is always 12 things, a gross is always 144 things, etc.). October 23 helps us to remember 1023. National Chemistry week is always the week that falls over that date.
High school students used National Chemistry Week to prepare chemistry related activities for the 2nd-4th grade classrooms. They practiced the activity and also came up with an explanation of the chemistry that caused it to occur at the level of elementary students. The high school students then presented their activities to the elementary students.
