Reviews Lesson 6.7. Reviews Lesson 6.7, the quick bread experiment: the variable and constants table from Day 1 Step 3 and the results from Day 2, with the four fizz cups and the acid rule. Play it between Day 1 and Day 2 as the Day 2 do now, or before the Cooking Methods Check, since Check items 9 and 10 are the leavening rule and the experiment's variable. Round 1 is the sort the science teacher would recognize; a student who puts the leavening in the constant bin gets the redirect line. Round 2 is the results, so play it after Day 2 or the game gives the ending away. The Batch E item is the grade 8 stretch and can be turned off for grade 6.

Worth knowing by heart:
- Baking powder and baking soda both make carbon dioxide gas when they get wet and hot. The gas makes bubbles inside the batter. The bubbles get trapped and push the batter up. The heat of the oven sets the batter around the bubbles, so the bread stays risen after it cools.
- Baking soda needs an acid, and baking powder does not, because baking powder already has its own acid mixed in with it.
- Four bowls, one difference, no cheating.
