Explain why scientific investigations should be replicable.


General Information

Subject Area: Science
Grade: 6
Body of Knowledge: Nature of Science
Big Idea: The Practice of Science -

A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation.

B: The processes of science frequently do not correspond to the traditional portrayal of "the scientific method."

C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge.

D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Lesson Plans

Name Description
The Human Catapult

Students will replicate an investigation to test a new amusement park ride, The Human Catapult. They will build a prototype catapult and compare their findings with that of the company, Innovative Engineering Design, Inc. Students will learn the importance of replication; the safety of future riders is at stake!

Scientific Replication MEA

This MEA explores the idea of replication when completing scientific investigations. Students are asked to create a plan for Science Incorporated to determine if their investigations are replicable.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Survivor Millennium!

Students will discover the importance of scientific replication by performing an investigation requiring them to write, and then follow, step-by-step instructions. The scenario will be based on the show Survivor and will involve making peanut butter and jelly sandwiches.

Is it valuable to repeat an experiment? It is important that experiments are repeated by other scientists. If similar results are not gathered, the conclusion(s) drawn would not have validity.
Replication or Repetition? Why bother?

Teacher will do demonstration mixing a clear liquid (vinegar) and a white powder (baking soda) resulting in a bubbling chemical reaction. The students will then be given the packages of materials and be asked to replicate the teacher's experiment, repeating their trial 3 times. Some groups will not be able to do this since their white powder is not baking soda, but cornstarch, which will not react with vinegar. Out of this discrepant event, the guiding questions will evoke the realization that accurate information is necessary to for replication of scientific investigations. Time will be spent differentiating replication from repetition.
