Precision Take 2
Funded Apr 14, 2022My AP chemistry students used the new balances for the very first lab this year; Determining the density of an unknown liquid. The added level of precision that these balances added to their work allowed all of my students to complete the laboratory exercise with less than 10% error. This would have been impossible with my former equipment.
My Honors Chemistry students also used the new balances with their first activity in which they had to determine both mass and length of bamboo skewers and then create a graph of their data. Again the added precision of these balances made this activity more meaningful as they can detect mass differences more easily.
I cannot thank you enough for the help for my students both now and into the future for this much needed resource.”
