“An ordinary leaf… yet it holds a secret!

The leaf starch test is a scientific experiment designed to detect the presence of starch—a product of plant photosynthesis. Fourth-grade students engaged in hands-on learning, observing changes in the leaves and using an iodine solution to test for starch.

This activity helps students understand the relationship between **light, water, and photosynthesis** while practicing scientific process skills, such as observation, questioning, experimentation, recording results, and drawing conclusions based on evidence.

Learn science through hands-on experiments, enjoy the thrill of discovery, and build understanding through personal experience.”
