1. Fill vase 1/4 full of water.
2. Add a fair amount of food coloring (10 to 20 drops) or more if your vases are large.
4. Check back every few hours to see how it's working.
5. At the end of your experiment, examine the whole plant carefully (stem, leaves, buds, petals, etc). What parts can you see the food color in? Most plants "drink" water from the ground through their roots. The water travels up the stem of the plant into the leaves and flowers. The plant uses the water to make food. When a flower is cut, it no longer has it's roots. But the stem of the flower still "drinks" up the water and provides it to the leaves and flowers. Note: Red and blue food coloring work the fastest. - 식물이 뿌리로부터 잎과 꽃에 물을 전달해 주는 경로를 관찰할 수 있으면 뿌리가 없어도 줄기를 통해 물을 제공할 수 있다.
