ESSENTIAL QUESTION: How do scientists develop scientific knowledge?
Why are good scientists often skeptical about claims made from experiments and how can they become more confident?
TOPIC: Other Scientific Investigations and Methods/Replication and Repetition
NGSSS: SC.8.N.1.1; SC.7.N.1.2
BENCHMARKS:
-Define a problem from the 8th grade curriculum using appropriate reference materials to support scientific understanding, plan and carry out scientific investigations of various types: systematic observations, or experiments, identify variables.
-Differentiate replication (by others) from repetition (multiple trials).
LEARNING OBJECTIVES: Students will be able to:
-distinguish between an experiment and other types of scientific investigations where variables cannot
be controlled.
-describe the common methods and models used in different fields of science and analyze the benefits
and limitations of them.
-differentiate between replication and repetition and evaluate the use and need of each in a scientific
investigation.
BELL RINGER- Topic 1 Assessment
Students took the topic one assessment.
Some classes began the lesson on other scientific investigations, doing the listening skills and completing the handouts mentioned in the previous blog.
Other classes began the repetition and replication power point lesson, completing the notes from the Alka-Seltzer lab and doing the independent practice handout as their exit slip.
There was no separate home learning assigned.
