Children will develop an understanding of how water travels through the stem to other parts of the plant.
36 - 60 months
0 - 8 tots
- 1 Long-stem White Carnation (1 carnation per water bottle)
- 1 Empty Water Bottle (1 water bottle for each different color used)
- 1 set Food Coloring (Assorted colors)
- 1 pair Scissors (Adult Use Only)
- 1 piece White paper, folded into fourths (This will be used to draw the carnation's progress.)
- Remove label from water bottle and fill about 1/3 full of water.
- Add enough food coloring to create a vibrant color (10-20 drops). Encourage child to help count as the drops are put in.
- Secure lid on water bottle. Gently shake bottle to mix food coloring with water. Once mixed, remove lid.
- Cut the stem at an angle to aid in water absorption.
- Help the child place the carnation into the colored water.
- Ask child to draw a picture of how the carnation looks at the start of the experiment. Label this picture "Start".
- Check every 2-3 hours for progress. At first notice of color change, ask child to draw a picture of how the carnation looks now and record the number of hours it has been in the colored water.
- Continue observation and recording until color transformation is complete. Make sure to record how the carnation looks at different time intervals.
- Once complete, ask child to look at his or her "Start" and "End" drawings and describe how the flower's appearance changed.
