Week 4 Assignment Guide
Use the following guide to help you complete the Week 4 simulation.
Visit the Reactants, Products, and Leftovers Simulation and then complete the following steps.
Click Sandwiches from the home screen.
Review the top of the screen, which shows a recipe for how to make a sandwich. Note that it takes 2 pieces of bread and 1 piece of cheese to make one sandwich.
Under the Before Reaction box, near the bottom of the screen, use the arrows to add 2 pieces of bread and 1 piece of cheese; these are called Reactants.
Note how one completed sandwich with no leftover ingredients appears in the After Reaction box. This is because you had just enough ingredients to complete the recipe with no leftovers.
Begin adding more Reactants (same as Step 3). Note what happens to the Products and Leftovers in the After Reaction box. Continue to make changes until you notice and feel confident about the patterns you are seeing.
Near the top right of the screen, change the recipe to Meat and Cheese. Notice the sandwich recipe becomes more complicated.
Repeat the steps you did for the previous recipe and see what patterns you notice.
Click Molecules at the bottom center of the page to switch the simulation view. Chemical reactions work the same way as your sandwich-making exercise. Experiment with the simulation until you notice patterns.
Chemical reactions work the same way as your sandwich-making exercise. Experiment with the simulation until you notice patterns.
If you would like to test your understanding, switch the simulation to Game. In this mode, you can try to figure out which reactants cause the products you see based on a given chemical equation (or vice versa in Level 2).
