PRODUCT DESCRIPTION

In this unique and effective lab activity, students learn to balance chemical equations using molecular models. This approach ensures that students do not make the common error of changing chemical formulas. Instead they learn to simply change the molar ratio of reactants and products by manipulating model molecules This activity is especially helpful in getting students to understand the meaning of coefficients in a balanced equation. This half of the bundle includes molecular models, formula models, lab introduction and procedure, analysis worksheet, and answer keys. Includes stoichiometry and energy exchange activities as well. Can be printed in color or gray-scale. The second half of the bundle includes the chemical equation balancing sheets; the two go hand in hand. I guarantee that your students will learn the how and why of balancing equations faster and with much better understanding than when using the traditional mechanical approach.

Materials provided cover two combustion reactions (think global warming) and photosynthesis. Their is a companion Power Point available (sold separately) that guides students through the first balancing activity as well.

This activity makes a difficult concept easy to understand in a very interesting and engaging manner. A must have for any chemistry teacher!

NOTE that the chemical equation balancing sheets (and answer keys) are now offered FREE of charge. If you purchase this Balancing Chemical Equations pack this is a must have - and its FREE!
