Benchmark Focus

Science

  • SC.5.E.7.3Recognize how air temperature, barometric pressure, humidity, wind speed and direction, and precipitation determine the weather in a particular place and time.

  • SC.5.E.7.4 Distinguish among the various forms of precipitation (rain, snow, sleet, and hail) making connections to the weather in a particular place and time. (Assessed as SC.5.E.7.3.)

    Common Core Integration

  • LACC.5.W.3.9: Draw evidence from literary or informational texts to support analysis, reflection, and research.

  • LACC.5.SL.1.1: Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 5 topics and texts, building on others’ ideas and expressing their own clearly.

  • LACC.K12.L.3.4 : Determine or clarify the meaning of unknown and multiple-meaning words and phrases by using context clues, analyzing meaningful word parts, and consulting general and specialized reference materials, as appropriate.

Claims

Claims

Claims are the statements that answer your original question.

  • The claim must be accurate, specific, and answer the question.

  • The claim is usually one sentence in length.


Evidence

Evidence

The evidence is all the scientific data that supports your claim.

  • It can come from a variety of sources such as:

    textbook, reading selections, videos, lab

    investigations, class notes, etc.

  • It should include both qualitative and quantitative data.

  • It is important to have numerous pieces of evidence in order to prove your claim.


Reasoning

Reasoning

  • Reasoning is the explanation that connects your claim to the evidence that supports it or why you think your claim (answer to the question) is correct .

  • It shows why the data you chose counts as evidence.

  • It shows a detailed understanding of the scientific principles involved and uses correct science vocabulary.

  • This explanation acts as a conclusion.

  • If evidence is from an experiment, it can be the “conclusion” of the lab.

  • It is usually several sentences in length.

When can a cer be used

When can a CER be used?

  • Use it to engage in structured, argumentation to explain a scientific concept.

  • Use it after an experiment to explain why a hypothesis was proven correct or not.

  • Use it to justify an answer choice for a multiple (FCAT type) test question is correct.

  • Use it to discuss claims made in videos or documentaries.


After an experiment

Multiple choice question

Multiple Choice Question

  • Claim

    – The correct answer choice is …

  • Evidence

    - Facts from background information

    - Data from the table or graph if applicable

  • Reasoning

    - Reasons for excluding other answer choices

    - Scientific background knowledge thatexplains

    why the answer is correct beyond what is given in

    the graph, table or background information.
