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- Probe Doing Science
Home learning 3 was collected.
Students viewed a power point on other scientific investigations and methods. They received the notes in handout form.
Students used listening skills to classify studies as either a controlled experiment, an investigation, or as a model.
Students also viewed a power point presentation on replication and repetition, sharing the Alka-Seltzer data to discover which data were believable and which were not. THe data was also used to demonstrate the difference between repetition and replication.
Students completed the independent practice handout on replication and repetition. The do no probe was redoing and submitted as an exit slip.
