🌱 Radish Growth Variables Mini-Lab

Using sample plants, nutrient solution cards, pH strips, moisture probes, and light meters, students test how environmental conditions can influence radish growth. The teacher models key ideas from plant biology, chemistry, and environmental science, then students rotate through quick trials and annotate a class evidence board with cause-effect possibilities. The session closes with teams identifying which variables seem controllable, measurable, and realistic for a school-based investigation.
