Grade 58 Performance Task
Contributed by: New York State Education Department
(NYSED)
NYS Alternative Assessment in Science Project (1996)
Description:
Students will interpret a graph of ocean depths
and topographic features.
This task assesses students' abilities to interpret
figures, organize and represent data, apply knowledge of scale
to a profile, and apply theoretical knowledge.
This task is designed to take students approximately
1520 minutes to complete.
Overall Task Content Area:

Earth and Space Science
Specific Knowledge Areas:

Structure of the Earth System
Performance Expectations:
National Science Education Standards:
8 ASI 1: Abilities necessary to do scientific inquiry
1.8 Use mathematics in all aspects of scientific inquiry.
Mathematics is essential to asking and answering questions about
the natural world. Mathematics can be used to ask questions; to
gather, organize, and present data; and to structure convincing
explanations.
8 DESS 1: Structure of the earth system
1.3 Land forms are the result of a combination of constructive
and destructive forces. Constructive forces include crustal deformation,
volcanic eruption, and deposition of sediment, while destructive
forces include weathering and erosion.

National Council of Teachers of Mathematics:
AL1: Understand patterns, relations and functions:
Grades 68 g. relate and compare different
forms of representation for a relationship
AL3: Use mathematical models to represent and understand
quantitative relationships:
Grades 68 c. model and solve contextualized problems using
various representations, such as graphs, tables, and equations
MEAS2: Apply
appropriate techniques, tools, and formulas to determine measurements:
Grades 68 j.
use common benchmarks to select appropriate methods for estimating
measurements
DAP3: Develop and evaluate
inferences and predictions that are based on data:
Grades 68 c. use observations about differences
between two or more samples to make conjectures about the populations
from which the samples were taken
PS2: Solve problems that arise in mathematics
and in other contexts:
Grades 68
CNX3: Recognize and use connections among
mathematical ideas:
Grades 68
REP3: Use representations to model and interpret
physical, social, and mathematical phenomena:
Grades 68
General Instructions to the Teacher:
This task is designed to take approximately 1520 minutes to complete.
Students will be working individually during this exercise.
Students should be ready to work as soon as the period begins.
The materials should be set out at each lab station, if possible.
A central supply area, if needed, should be easily accessible. All
supplies should be clearly labeled.
Materials for "Ocean Bottom Profile":
The teacher will not need any materials.
At each station students should have:
 Ocean Bottom Profile (fig. 1)
 Calculator
Advance Preparation:
None
Safety:
 Be careful.
 Teachers and students should always exercise appropriate safety
precautions and utilize appropriate laboratory safety procedures
and equipment when working on science performance tasks.
