Beaker directions: • Measure the liquid in the beaker. Look at what the lines stand for (these are very limited in their ability to measure). Account for all digits on the instrument and then add 1 estimated digit. • If there is not a line for a place value (1, 2, 3...), then that is the furthest you can estimate!
