Grade 3 Science
Testing Materials and Designs
Students will:
-Recognize that functional structures must be sufficiently strong and stable and that unstable structures are often unsafe to use
-Compare and evaluate the strength and stability of different models or objects constructed
-Describe the properties of some common solids, such as wood, paper or plastic that make them suitable to use as building materials
-Apply procedures to test the strength of construction materials, in particular different stocks of paper, plastics or wood.
-Apply procedures to test different designs
-Apply procedures to test the strength of different methods of joining
-Identify and apply methods for making a structure stronger and more stable

Hearing and Sound
Students Will:
" I can describe sound and show ways of making and controlling sound"
" I can identify examples of vibration"
"I can recognize that sound is the result of vibration, and I know that the larger the vibration the louder the sound"
" I can recognize that loud sounds pose a danger to the ear"
"I can tell you that pitch is the result of differences in the rate of vibration, and I can predict how a change in the rate of vibration will affect the sound"
"I can identify examples to show that sound can travel through a variety of materials, including solids, liquids and air.
"I can describe how the human ear senses vibrations"
"I can explain the role that sound plays in communication"
