Notes from Janice’s Desk
Most of my books use measuring tools that you have at home. I am not minimizing the importance of learning to use science equipment. My thought is that by mastering measuring skills using familiar instruments, kids will be more successful in using science instruments.
I am happy and honored that kids and educators around the world use my books, both English measurements and metric measurements are given. The units of measurements for these two systems are not difficult to learn. Measurement conversion is generally the problem. How many liters are in a gallon? Rarely is this knowledge needed. But if gasoline is sold at one company for $2.40 per gallon and a nearby company is selling the same fuel for $0.70 per liter, it would be nice to know which is a better deal. For the measurement conversion between the volume measurements of liter and gallon, see LITER VS. GALLON.
Because I am so accident prone, when possible I use plastic measuring tools–even in the kitchen. Whether you use plastic or glass will be your own decision.
For a measuring cup activity, seeVolume: Using a measuring cup
