science fair project flowers and different light sources alex pappas
TRANSCRIPT
Project Overview
• I will take two flowers and both put them under a different light source. They both got the same amount of light, soil, and water. They both stood in the light for the same amount of time each day.
Research
• Read book about flowers• Search internet for flower facts.• Searched internet for fast growing flowers.
Variables
• Independent: Amount of light• Dependent: Height of flowers• Constants: Time of day, 1 hour in sun, type of
flowers, cup of soil (12 cm), cup of water (100 mm).
• Control Group: Flower heated by the sun
Hypothesis
• Hypothesis• If flowers can grow in the sun then they can
grow under a lamp because they both give off heat
• My educated guess was that the sun would make the flowers grow faster because most plants are used to growing in the sun. The sun made the flower grow faster.
Procedures
1. Buy 2 of the same type of flowers2. Put 12 cm for each cup3. Put 1 flower in each cup4. Give each flower 100 mm of water each day5. Put 1 flower in sun for 1 hour6. Put one flower under lamp for 1 hour7. Take flowers out of light 8. Put them in a room temperature room overnight

Flower 1 (lamp)Floweer 2 (sun)
As you can see the 2nd flower grew more.
They started out at different heights but the 2nd grew more.
Conclusion
• I concluded that the sun made the flower grow better. I gave the flower more pedals, and taller.
Possible Experimental Errors
• The errors could have been that the different heights of the flowers made one go through its growth spurt and the other already been through it.
Applications and Recommendation
• For improvements I would recommend buying flowers that are the same type. Start the project a little bit early incase there are any problems.
