Thank you for participating in the webinar "Experience Stoichiometry." You will be using the features on this Google site to participate in the interactive components of the webinar. Please follow along and use the various tools as they are discussed.
With your team, sketch physical models of the products and the reactants. In a class, you could construct physical models instead.
Students can cut out the N and H atoms models from the following worksheet: Atoms.
Using your physical model/sketch complete the table. Of the four ways shown for quantifying the reactants and products, which have the same amount on both sides?
Choose someone from your group to report your results. The reporter should write down the group's table, since the Zoom whiteboards will disappear when discussion ends.
Atoms and Mass are Conserved
Imagine you had constructed the physical models of the products and reactants instead of sketching them. Design an experiment you could perform to test whether or not mass is conserved. One member of your group will report on your design and some of its limitations.
- Complete the tables
- Graph the products as a function of the reactants
- Determine the slopes
The Science of Doing
Meet the all-new Experience Chemistry high-school program. It gets students to investigate real, compelling phenomena – and experience how chemistry relates to their everyday lives. Is there chemistry in water, food, medicine, or the latest sports shoe? Hands-on and digital activities encourage students to figure things out. Experience Chemistry was built from the ground up for the NGSS and designed using the research-verified 5E Instructional Model.
Multiple Representations in Physics
Having students move back and forth through multiple representations of the same phenomena is research-validated and pedagogically crosscutting. Check out a similar workshop we do for physics called "Experience Kinematics."
