My students need scientific calculators in chemistry to solve and to calculate stoichiometry problems.

Hooray! This project is fully funded
How many atoms are found in 8.3 moles of potassium? Remember in high school chemistry, when we all discovered that there was actually A LOT of math in chemistry? Imagine trying to solve stoichiometry problems... WITHOUT scientific calculators.
My students are mostly high school upperclassmen in an urban community.
Most aspire to graduate from high school and to enroll in a four-year university. At times math can be challenging for some students, but they are making great strides in learning the math of chemistry.
This semester we are learning about chemical reactions, kinetics, gases, and molecular theory... all topics that involve A LOT of mathematical calculations. Stoichiometry in chemistry includes many calculations, such as when students are converting from grams to particles, moles to grams, molecules to grams, and/or are calculating the molar mass of chemical compounds. If students had scientific calculators available, we would be able to engage a lot more with chemistry concepts that heavily involve math.
Currently, we have very few calculators to go around.
Without the use of calculators, we are only limited to completing stoichiometry and other mathematical problems that include easier numbers to simplify. These numbers are neither challenging nor realistic of measurements they might encounter in real life or in college. Stoichiometry in chemistry can be extremely fun and more interesting when students are actually using challenging numbers!
