Stoichiometry: Proof Is in the (Rice) Pudding
Materials:
Bag of rice
Bag of seasoning
Deionized water
500 mL beaker
Glass stirring rod
Hot plate
Digital scale
Measuring cups ( 1/3 cup, 1/8 cup)
Cooking Instructions:
Measure the amount of rice, water, and season you are asked to use to cook the rice. Measure the ingredients in both measurement units as well as in grams. Record the values in your report.
- Add your rice, seasoning, and water into your beaker and place on a hot plate on “high” setting.
- Stir gradually with a glass stirring rod until all water has evaporated. Record what you observe as your rice’s consistency (sticky, crunchy, or just right).
- How does this result compare to the other groups?
- What do you think was the difference between the other groups? Who had the correct recipe? [Hint: we will reveal this together as well]
