LEMON JUICE AND FLOWERS

PRESENTATION BY

HMMM....

If flowers are put in a vase with water and lemon juice, then the flowers will not wilt because lemon juice will give the flowers vitamins.

INDEPENDENT AND DEPENDENT VARIABLES

THE GROUPS

• Experimental-with lemon juice
• Control-just plain water

MATERIALS

• 1/4 cup lemon juice
• 2 vases
• 4 flowers
• 2 cups water

CONSTANTS

• Both have water
• Same vases
• Same flowers and number of flowers
• Same water source
• Same amount of water
• Same amount of water
• Same amount of sun and shadow
• Same area
• Same number of petals

PROCEDURE

• Fill one vase (vase A) with 295ml of water and the other (Vase B) with 236ml of water
• Add 59ml lemon juice to vase B
• Put two flowers in each vase
• Collect observations- Shown on next slide
• Repeat step 5 every day at 6:00pm

OBSERVATIONS

• Quantitative
• Count number of petals wilted per flower-find average
• Measure length from bottom of stem to tip of flower
• Qualitative
• Describe color of flowers
• Smell from 5 inches away

Analysis
Some flowers completely bent over on Days 6&7. All the flowers curled at the edges on days 2-7. I was surprised that the flowers didn't change more. The lemon juice did not do anything or possibly made the flowers worse.

Conclusion
The hypothesis was that if flowers are put in a vase with water and lemon juice, then the flowers will not wilt because lemon juice will give the flowers vitamins. The results did not support the hypothesis because both the flowers in the lemon juice completely bent over, while only one did in the water. Also, the other in the water was the most healthy. I would probably change the expirament by adding a different citrus, e.g. orange, grapefruit, or lime juice.
