Rising to the Occasion: The Science of Food Lift
Join the Science History Institute’s Lisa Berry Drago for what just might be the greatest Varsity Tutors class since sliced bread.
Wheat is far from fluffy. In fact, the main ingredient in breads and cakes is specifically called a grain. So how do your baked goods get that delightfully soft texture (and taste)? Find out in this exploration of the history and chemistry of the ingredients that make your food rise to the occasion. You’ll even try your own “balloon race” experiment as you test different mixtures of yeast and sugar to give your food flight. And along the way, you’ll examine ancient processes of leavening, see modern mass-production techniques, and meet founders of contemporary food science.
What you’ll need:
- 2 empty plastic water bottles
- 2 balloons (not inflated)
- 2 cups of warm (not boiling) water
- 2 packets of yeast (instant is best)
- sugar (at least 2 tablespoons)
- honey (at least 2 tablespoons)
