Administration Procedures

Grades 9-12 Performance Task
Contributed by: New York State Alternative Assessment in Science Project (NYSED)

Description:

Students examine graphical data describing the behavior of paramecia under various conditions. They determine patterns, make predictions, and describe basic physiological processes.

The task assesses students' abilities to identify patterns, make predictions, and utilize their understanding of basic physiology.

This task is designed to take students approximately 20-30 minutes to complete.

Overall Task Content Area:

Life Science

Specific Knowledge Areas:

The behavior of organisms

Performance Expectations:

formulating conclusions from investigational data
applying scientific principles to develop explanations and solve new problems

National Science Education Standards:

12 A SI 1: Abilities necessary to do scientific inquiry: Grades 9-12
1.4 Formulate and revise scientific explanations and models using logic and evidence. Student inquiries should culminate in formulating an explanation or model. Models should be physical, conceptual, and mathematical. In the process of answering the questions, the students should engage in discussions and arguments that result in the revision of their explanations. These discussions should be based on scientific knowledge, the use of logic, and evidence from their investigation.

12 C LS 6: The behavior of organisms: Grades 9-12
6.2 Organisms have behavioral responses to internal changes and to external stimuli. Responses to external stimuli can result from interactions with the organism's own species and others, as well as environmental changes; these responses either can be innate or learned. The broad patterns of behavior exhibited by animals have evolved to ensure reproductive success. Animals often live in unpredictable environments, and so their behavior must be flexible enough to deal with uncertainty and change. Plants also respond to stimuli.

National Council of Teachers of Mathematics:

DAP1: Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them:
Grades 9-12 l. understand the meaning of measurement data and categorical data, of univariate and bivariate data, and of the term variable
Grades 9-12 m. understand histograms, parallel box plots, and scatter plots and use them to display data

AL3: Use mathematical models to represent and understand quantitative relationships:
Grades 9-12 f. draw reasonable conclusions about a situation being modeled

PS2: Solve problems that arise in mathematics and in other contexts:
Grades 9-12

CNX3: Recognize and apply mathematics in contexts outside of mathematics:
Grades 9-12

General Instructions to the Teacher:

This task is designed to take students approximately 20-30 minutes to complete.

Students will be working individually during this exercise.

Students should be ready to work as soon as the period begins.
