Alaska Science Performance Standard L1/B5

Alaska Science
Key Element B5

A student who meets the content standard should employ ethical standards, including unbiased data collection and factual reporting of results.

Performance Standard Level 1, Ages 5–7

Students differentiate between what they observe with their senses and what they interpret about those observations.

Sample Assessment Ideas

Students touch a dry sock and a wet sock; measure the temperature of each; report on whether or not they are the same temperature; discuss the accuracy of their interpretation.
Students observe a bird, squirrel, or class pet; make a chart of their observations and interpret their behavior.

Expanded Sample Assessment Idea

Expanded Sample Assessment Idea

Students identify an object in a black box using only one sense; share observations with other students who used other senses; compare conclusions about the nature of the object using single vs. multiple senses to observe.

Procedure Students will: Divide into sensory groups: smell, touch, and hearing. Explore objects (such as seaweed, jerky, mashed berries) using only one sense; no one will see or taste it. Reorganize so that each new group contains a child who used a different sense. Repeat so that each group will have each sense represented. Share the observations, try to identify the object, and differentiate between observations and inferences. Reflection and Revision Determine what senses provided the most accurate inferences about the identification of the objects.	Levels of Performance
	Stage 4	Student work is complete, correct and shows evidence of elaboration and extension. Students report detailed observations and inferences and differentiation between the two.
	Stage 3	Student work is generally complete, correct and may show evidence of elaboration and extension. Students report observations and inferences and differentiation between the two though minor errors may be present.
	Stage 2	Student work may be incomplete or incorrect and shows limited evidence of ability to report observations, make inferences or differentiation between the two.
	Stage 1	Student work is mostly incomplete and incorrect. Student makes limited observations or is unable to use observations to identify the object in the black box.

National Science Education Standards

Scientists make the results of their investigations public; they describe the investigations in ways that enable others to repeat the investigations. (Page 123)

Scientists review and ask questions about the results of other scientists’ work. (Page 123)

Benchmarks

A lot can be learned about plants and animals by observing them closely, but care must be taken to know the needs of living things and how to provide for them in the classroom. (Page 15)
