Learning as a Science
TASK 3
Increasing Understanding and Knowledge Retention
Western Governors University

Introduction
Lesson Identification
Subject: Physical Science
Grade Level: 8th-grade
Objectives: Students will be able to…
1. Model a longitudinal (compression) wave and diagram, label, and describe the
components (wavelength, compression, and frequency) (2019)
2. Model a transverse wave and diagram, label and describe the components
(wavelength, amplitude, frequency, crest, and trough) (2019)
3. Compare longitudinal and transverse waves and their characteristics (2019)
Standard(s): PS.6.a - The student will investigate and understand that waves are
important in the movement of energy. Energy may be transferred in the form of longitudinal and
transverse waves. (2019)
Drawing or Summarizing
“Across a series of experiments, researchers found drawing information to be a powerful
way to boost memory, increasing recall by nearly double.” (Terada, 2019). To help student
retention, I can incorporate drawing into the direct instruction and notes part of the lesson. A
specific example of this would be having my students draw and label the different properties of
both transverse and longitudinal waves. Some students experience increased retention when
learning by auditory delivery, while some students have a higher retention rate when learning by
visual delivery. By having students draw a picture in addition to labeling the definitions of the
different properties, I am giving students multiple ways to learn and retain the necessary content.
