Students will use a double pan balance to determine the mass of the heaviest
and lightest objects.
How can we find out
which object is heavier?
Demonstrate to the students a balanced double pan balance.
Tell the students that a balance is used to compare the property of mass of two

Select two objects from around the classroom. Ask the
students to predict which object is heavier. Place one object in one basket and
the other object in the other basket and observe.
Compare several objects such as a crayon, balloon, marble,
spoon, button, styrofoam peanut, cork, and rubber band using the double pan
balance. Have students draw the heaviest/lightest object on the activity sheet for Learning Experience 6 in
the Properties Student Activity Book. (Please see PDF
