Exercise 1. Lena and Bryan were weighing their lunch boxes for a science experiment. Both got the same number on the balance: 500. Lena wrote 500 grams (g) in her notebook, while Bryan wrote 500 milliliters (mL). uestion: If you were their classmate, how would you explain to Bryan why Lena's answer is correct when measuring mass?
Answer (1)
I would tell Bryan that grams measure how heavy something is, but milliliters measure how much space it takes. Since they were weighing lunch boxes, they should use grams like Lena did.
