Nothing like a fun little experiment to poke the curiosity of young minds. KIOS (Karya Ilmiah dan Olimpiade Sains) club is on the move. The cabbage water movement experiment is very simple but demonstrates how plants work in a straightforward–and colorful–way.
What do we need?
- 1 Cabbage
- At least two clear containers
- Food coloring in several shades
- Water
What to do?
- Slice the cabbage from the stalk. Place at least one large piece of cabbage (stalk included) into each container.
- Pour water into each container.
- Add a few drops of food coloring to each container. Use a different color in each.
- Wait and observe!
Let’s check our activities!
Our findings
Plants like cabbage have tubes in them called xylem that allow them to pull water from the ground and move it up through their leaves. This is how plants “breathe.” So, when you put cabbage in water with food coloring in it, you’ll get to actually see the water’s movement from the stalk up through the leaves.
This has the added bonus of coloring the xylem within the plant so you can see the path water takes through it. It’s simple, educational, and actually really nice to look at when all is said and done!
