Reflection: Discourse and Questioning Wave Behavior Lab Rotation: Day 2 - Section 4: Wave Behavior Lab Rotation - Day 2


Science discourse is important to the success of these lab stations.  It is important that students practice having real conversations about science and have the ability to share contradicting opinions and question each others beliefs in a respectful way founded in science.  In this video, the students may be "debating"how to create the appropriate wave and may have differing viewpoints; however, they do not get defensive or take any questions as an insult.  They know that part of science and inquiry is both generating questions and defending claims.  Both students in the conversation have an important role.  They are questioning each other about a common misconception that students have which is confusing amplitude with frequency.  The frequency of a wave is independent of amplitude; however, students often think that "faster" means more amplitude.  In this clip, the students recognize that amplitude isn't increased by moving faster (by frequency), but by moving their hand a larger distance side to side.  Building a classroom culture that supports science discourse will increase both engagement and learning.

Wave Behavior Lab Rotation: Day 2

Unit 1: Waves: An Introduction and Exploration of Wave Properties
Lesson 6 of 7

Objective: Students will be able to create simple mathematical representations of waves and identify characteristic properties of waves.

Big Idea: Students go through a series of hands-on lab stations that engage students in not only identifying the properties of waves, but in creating mathematical representations as well!
