Does anyone else find the gram measurements on food labels abstract?
I truly would like to see the U.S. start using more metric units. All scientific measurements are taken using metric units. It is easier to make conversions between units by simply multiplying by 10 or 100 or 1000 instead of multiplying by 12 or 3 or 5280 or 16. Not only is it easier to make conversions within length or volume, did you know that a mL is 1cubic cm and 1 mL of water weighs 1 gram?
When we have a solid understanding of what a gram looks like, it makes food labels so much easier to understand.
We started by taking the boys favorite cookie recipes and measuring the ingredients first in English units then weighing out and recording the weight in grams. Liquid measurements were easy because our measuring cup is marked in both mL and cups.
This simple “experiment” :
1. Develops an understand of metric units by making concrete connections.
2. Develops a greater understanding of volume v. weight. A cup of sugar weighs more than a cup of flour.
3. Provides a chance to practice good lab skills.
Plus, we get to eat cookies!
