Inquiries in Science: Calculating with Stoichiometry Kit

2 Items Exclusive
$52.75 - $157.95 View Details

Grades 9–12. Students first use manipulative cards to set up and practice stoichiometric problems. They then obtain data from chemical reactions, which they compare with the results of stoichiometric calculations and determine the percent yield. In the concluding activity, students design and conduct their own experiments to determine the mass percent of sodium bicarbonate in antacid tablets. Materials are sufficient for 32 students working in groups of 4.
