Waves Carry the Pattern: Science Unit 2, Grade 4 (Letters & Devotion)

Description

Waves Carry the Pattern is Unit 2 of Energy, Waves, and Living Systems: Grade 4 Science (Grade 4), the Letters & Devotion Science course, complete in one printable PDF: 8 lessons, the unit check-up and the answer key, 50 pages.

• The physical features of a transverse wave (crest, trough, amplitude, wavelength)
• The distinction between the motion of the medium and the motion of the wave pattern
• The relationship between shake speed and the resulting wavelength and amplitude of a rope wave
• The cause-and-effect relationship between wave energy passing through water and the limited motion of a floating object
• The categorical difference between wave-pattern transfer and object transfer, applied to new examples
• Application of the wave-pattern-versus-matter-transfer model to an unfamiliar real-world context (a wave pool)
• Measurement and recording of amplitude and wavelength using a physical rope-wave setup
• A claim-evidence-reasoning explanation of matter-versus-pattern motion in a wave, using the summative rope investigation as evidence

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
