For the class:

Wood (oak, mahogany, walnut, pine)

Plastic (clear, green)

Metal (aluminum, brass, steel)

Balance stand

Basic Skills Development:

Listening

Speaking

Testing

Observing

Comparing

Predicting

Evaluation Strategy:

Students will place in serial order several objects of the same shape and size by using a double pan balance.

Vocabulary:

oak

mahogany

walnut

pine

aluminum

brass

steel

Objective: Students will determine if objects of same shapes and sizes are heavier or lighter and if different objects may have some common properties and still be different objects.

What properties do all of these objects have that are the same? (shape and size)

Using the material samples provided, place a piece of metal in one basket and a piece of wood in the other basket to find out which is heavier or lighter. Start with only two objects. Determine which is the heaviest. Add another object and determine where it would be placed in serial order with the first two objects. Add another object and continue this process until the students can arrange all eight objects in serial order from lightest to heaviest. Have students record their information on the activity sheet for Learning Experience 9 in the Properties Student Activity Book. (Please see PDF)

Discussion Questions:

How can we find out if objects made of different materials, but are the same size and shape weigh the same?
