Evaluation Strategy:

Given several objects, students will use the double pan balance to weigh items from lightest to heaviest.

Vocabulary:

balance

compare

heavier

lighter

mass

predict

Objective: 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 different objects. Gravity will pull harder on the object that has more mass.

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) Students will color in red the heaviest object on the activity sheet for Learning Experience #6 in the Properties Student Activity Book.(Please see PDF) Add mass words to the property word chart. Include such words as heavy or light.

Discussion Questions:

Which object is the heaviest?

Which object is the lightest?

Extension:

Have students arrange all the objects from lightest to heaviest.
