Growing garlic in a window box turns a kitchen staple into a semester-long science investigation for grades 3 through 6. The sheet opens with the guiding question of how bulbs form underground, walks students through an eight-step procedure, and provides a structured observation table where they log the date, days since planting, shoot height in centimeters, visible leaf and color changes, and any sketches or notes. A dedicated results box asks students to describe their harvested bulbs, and the conclusion section prompts them to evaluate their original hypothesis.

This homeschool worksheet fits naturally into a plant biology unit study, a botany sequence, or a standalone long-term observation project. Because the experiment runs four to six months from planting to harvest, it builds habits of consistent scientific recording that a single-session lab cannot. A student who completes this sheet demonstrates understanding of bulb propagation, plant response to light and water, and the relationship between above-ground growth and underground development.
