Ocean Waves - Task A
Lesson
Alignment and Connections of Task Components to the Standards Bundle Task Component A asks the students to draw an ocean wave and to connect the general components of a wave (amplitude, wavelength, frequency) to the components of an ocean wave (wavelength, period, height). This addresses parts of NGSS core idea of PS4.A: Wave Properties as it relates to MS-PS4-1, and partially addresses one part (one Appendix F bullet) of the NGSS practice of Developing and Using Models. By developing algebraic equations relating height to amplitude and frequency to period, students are partially addressing the CCSS-M content standard 8.F.5 (students are not asked to describe the relationships but rather are given the descriptions and asked to make a sketch), and fully assessed on 8.F.4 and the CCSS-M practice MP.4. Mathematically relating the components of an ocean wave with the standard components of a mechanical wave enhances assessment of the science standards associated with waves whereas the science context provides a practical use for developing mathematical relationships.
