Science Assessment Map – Sample at 3.75
Sound
Context 1
The students were asked to investigate how sounds are produced using a variety of examples. Students used a variety of musical instruments and their own voices to observe the effects of vibration.
The elements of the Science knowledge and understanding standard addressed by the task are:
(Students) explain change in terms of cause and effect.
Students use everyday examples to illustrate the transforming and transferring of energy.
Sample
The following work sample, and the related Science 3.75 progression point examples, illustrate the kinds of responses that students produce as they progress towards the Level 4 standard.

Science knowledge and understanding – 3.75
A. Notes feeling the vibration but no further explanation offered.
B. Indicates cause and effect with the music hitting the balloon causing the balloon to shake in sympathy.
Context 2
The students were asked to investigate how the ear processes sounds so that we can hear them. They were asked to explain in their report how sounds are heard as a result of vibrations travelling through the air, reaching the ear and being converted to nerve signals which are interpreted by the brain.
The element of the Science knowledge and understanding standard addressed by the task is:
(Students) identify and explain the connections between systems in the human body and their various functions.

A. Explains some of the process in the written sample but does not explain how the signals get to the brain.
Context 3
The students were asked to investigate how the ear can be protected from loud sounds. They investigated how loud sounds can damage hearing.
The element of the Science knowledge and understanding standard addressed by the task is:
(Students) explain change in terms of cause and effect.
