| | |  |  | 하얀 카네이션이 색소 담긴 물에 담가 놓았을때 어떻게 변하는지를 알아보고 식물 부위의 명칭도 함께 알아본다. | |
|  | | |  |  | white carnations, flower vase(s), food coloring, water | |
| | | |  |  | 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. | |  | | | 3. Put a flower in each vase and let it sit for a day. Just like you would for any cut flower, have an adult trim the stem at an angle before placing it in the vase.
| | | | | 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. | |
