四年級學期課程，以工程為重點（第 3 部分，共 4 部分） 9 週科學學期課程 |帶報告卡

[3rd of four 9-week sessions]
This course takes a modified, thematic approach to 4th Grade Science. It offers content that is typically taught during the third 9-weeks in a traditional 4th grade science class. The students will learn about the structure and function of waves. The students will take an in-depth look at science from an Engineering perspective. 

The following topics will be discussed:
Unit: Waves
Week 1 - Wave Structure
Week 2 - Types of Waves
Week 3 - Amplitude & Wavelength
Week 4 - Wave Energy
             - Doppler Effect
Week 5 - Wave Information transfer examples
Week 6 - Analyze and interpret data from maps to describe patterns of Earth’s features
Week 7 - Digitized signals & Wireless communication
Week 8 - Bluetooth, Fiber Optics
Week 9 - Analyze and interpret animal sense of wave patterns

Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; there is no net motion in the direction of the wave except when the water meets a beach.
Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks)

The students will learn the structure of waves. Different modes of instruction will be used. The students will be taught using pictures, video clips, slides, discussions, lecture, independent reading, and open-ended questions. The students will learn the types of waves. This will be taught using pictures, video clips, slides, discussions, lecture, independent reading, and open-ended questions. Students will learn about the energy in waves. This will be taught using pictures, video clips, slides, discussions, lecture, independent reading, and open-ended questions. The students require the 3rd grade science course. The fourth 9-weeks course will pick up where this course leaves off.
