FoodMASTER Middle: Weights and Measures
Students will use common household measurement tools and scientific measurement tools and various methods of measurement to compare for accuracy. Students will also calculate percent error by comparing their measurements to actual values and apply these principles to analyze and decipher the components of a food as indicated on the Nutrition Facts label.
