Massachusetts Comprehensive Assessment System

2017, High School Biology

Download PDF Document  Question 32: Open-Response  
The human skeletal system has many important functions, including movement. As a person ages, movement can become difficult. Ligaments become less elastic and cartilage is damaged.
  1. Considering the function of ligaments, explain why less elastic ligaments could cause movement to be difficult.
  2. Considering the function of cartilage, explain why damaged cartilage could cause movement to be difficult.
  3. Identify two functions of the skeletal system besides movement.

Scoring Guide and Sample Student Work
Select a score point in the table below to view the sample student response.

ScoreDescription
4 The response demonstrates a thorough understanding of the skeletal system and its roles in the body. The response clearly explains why less elastic ligaments and damaged cartilage could cause movement to be difficult, and correctly identifies two functions of the skeletal system.
4
3 The response demonstrates a general understanding of the skeletal system and its roles in the body.
2 The response demonstrates a limited understanding of the skeletal system and its roles in the body.
1 The response demonstrates a minimal understanding of the skeletal system and its roles in the body.
0 The response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.

Note: There are 2 sample student responses for Score Point 4.
