Effect of Music on Plant Growth Lab Sheet
Three pots, one question: does sound actually change how a plant grows? This lab sheet walks your student through testing the effect of music on plant growth with a controlled, repeatable setup.
Your grades 4-6 homeschooler plants three identical seedlings, labels them Plant A (Music), Plant B (No Music), and Plant C (Different Music optional), then tracks height in centimeters every few days for up to two weeks. The sheet walks through the full scientific method: a fill-in hypothesis section, a nine-step procedure, a variables box identifying the independent variable (exposure to music) and controlled variables (pot size, soil, watering schedule, sunlight), and an observations table with rows for days 1 through 14.
Testing the effect of music on plant growth fits naturally into a plants and living systems unit study, and it works especially well as a standalone long-form experiment that builds habits of daily observation and honest data recording. By the end, your student writes a conclusion grounded in their own height measurements and answers three reflection questions asking what they noticed, which plant grew most, and what they would change in a repeat experiment.
Grades 4-6 homeschoolers investigate the effect of music on plant growth across three labeled pots over two weeks.

Usage Notes
Nearly everything on the materials list is already in most homes: potting soil, identical pots, water, a ruler, labels or tape, and a marker. The one variable is a speaker or device to play music, which any phone or tablet handles. No safety concerns are implied beyond keeping all plants in the same sunny location so conditions stay controlled.
Printing Tips
Slip a single sheet into a plastic page protector at the start of the experiment so it survives two weeks of daily watering and handling without going limp. The observations table has enough rows that students will be writing in it repeatedly, so 24-pound paper holds up better than standard copy stock if you are keeping it loose on a clipboard.
