with our eyes and what we know about colors
How do we find length of an object?
use a ruler or tape measure. Measure from one end to the other.
What is flexibility?
ability to bend without breaking
What is absorbency?

use a balance
What do we use to determine texture of an object?
our hands
how do we determine how hard an object is?
Scratch it with a nail or coin and see fi it leaves a mark
How can we test an objects strength?
by trying to bend it
