Grade 5-8 Performance Task
Contributed by: New York State Education Department (NYSED)
NYS Alternative Assessment in Science Project (1996)
Description:
Students will read and interpret the information from
a barograph from a major winter storm.
This task assesses students' abilities to interpret
and analyze graphs, construct data tables and graphs, generalize,
infer, apply knowledge of meteorology, and explain scientific relationships.
This task is designed to take students approximately
20 minutes to complete.
Overall Task Content Area:
- Earth and Space Science
Specific Knowledge Areas:
- Structure of the earth system
Performance Expectations:
- organizing and representing data
- formulating conclusions from investigational data
- applying scientific principles to develop explanations
National Science Education Standards:
8 D ESS 1: Structure of the earth system: Grades
5-8
1.10 Global patterns of atmospheric movement influence local
weather. Oceans have a major effect on climate, because water in
the oceans holds a large amount of heat.
8 A SI 1: Abilities necessary to do scientific inquiry:
Grades 5-8
1.4 Develop descriptions, explanations, predictions, and
models using evidence. Students should base their explanation on
what they observed, and as they develop cognitive skills, they should
be able to differentiate explanation from description — providing
causes for effects and establishing relationships based on evidence
and logical argument. This standards requires a subject knowledge
base so the students can effectively conduct investigations, because
developing explanations establishes connections between the content
of science and the contexts within which students develop new knowledge.
1.5 Think critically and logically to make the relationships
between evidence and explanations. Thinking critically about evidence
includes deciding what evidence should be used and accounting for
anomalous data. Specifically, students should be able to review
data from a simple experiment, summarize the data, and form a logical
argument about the cause-and-effect relationships in the experiment.
Students should begin to state some explanations in terms of the
relationship between two or more variables.

National Council of Teachers of
Mathematics:
Algebra (AL1): Understand patterns, relations
and functions.
Algebra (AL3): Use mathematical models to
repesent and understand quantitative relationships.
Algebra (AL4): Analyze change in various
contexts.
Problem Solving (PS2): Solve problems that
arise in mathematics and in other contexts.
Representation (REP1): Create and use representations
to organize, record, and communicate mathematical ideas.
General Instructions to the Teacher:
This task is designed to take approximately 20 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 "The Blizzard of 1993":
At each station students should have:
- barograph from March 13-19, 1993
- ruler or straight edge
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.
Extensions/Modifications:
Students could examine other barographs from other blizzards.
