CBSE > Class 06 > Science (OLD)

Yogita Ingle 8 years ago

Materials

3-4 Water Glasses
Water
Food coloring
3 or 4 fresh white carnations
Ruler
Sharp knife
Cutting board

Procedure

Fill each of the three water glasses with a half cup of water.
Add twenty drops of food coloring.
Stir the food coloring into the water.
Ask a grown-up to help you cut the last centimeter off the white carnation. You should cut the stem at a 45 degree angle.
Immediately put the flower in the food coloring.
Do not disturb the flowers. Observe them after 2, 4, 8, 24, and 48 hours, paying special attention to the bottom of the stems.
If desired, cut 4 or so centimeters off the stem of one of the finished flowers to observe it more closely.

Results

After just a couple hours, you might notice the food coloring in the stem. After twelve or so hours, the food coloring should tint the vessels within the flower. Your results will vary depending on the quality of your flowers and cutting. When you observe the bottom of the stem, you will probably notice the round xylem tubes are filled with food coloring.
