How to Grow a Potato Plant from Scraps

SciShow Kids

Join Jessi and her robot rat friend Squeaks in this hands-on science lesson about vegetative propagation. The video explores how potatoes are unique compared to many other plants because they are typically grown from other potatoes (tubers) rather than seeds. Jessi guides viewers through a step-by-step experiment to sprout a potato using simple household materials like a cup, water, and toothpicks, turning a common grocery item into a living botany lesson. The content covers key biological concepts including plant life cycles, the function of "eyes" on a potato, and the differing needs of plants at various growth stages. It explains why potatoes start growing underground in the dark and when they need to be moved to sunlight to support photosynthesis. The video also details the full timeline of the plant's life, from initial sprouting to the flowering stage, and finally to the withering of leaves which signals harvest time. This video is an excellent resource for early elementary classrooms as it demonstrates an accessible, low-cost experiment that every student can participate in. It encourages long-term scientific observation, data recording, and understanding where our food comes from. Teachers can use this to introduce units on plant biology, agriculture, or to practice procedural writing and following scientific instructions.
