DIGITAL DOWNLOAD: you receive a printable US Letter PDF to print at home or school. No physical book is shipped.

The longest workbook at this grade band, this one pairs pitch and ear activities with a full answer key that speeds up marking. A "What Vibrates?" task opens the book, and "Further Away, Fainter" has students record real volume data from different distances. "Why Is It Higher?" explains pitch directly before "Match the Noise Words" pulls the vocabulary together, and a closing ruler test lets students investigate pitch for themselves, changing one variable at a time. A reflection task appears throughout, finishing with a word bank of sound words. NGSS codes 1-PS4-1, 4-LS1-2 and 4-PS4-1 are covered.
