Science Fair Project Flowers and different light sources Alex Pappas
Statement of the Problem • Will flowers grow faster under different light sources?
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.
Materials • Ruler • 1400 mm of water • 24 cm of soil • Flower (x2) • Cup for soil (x2) • Lamp • Sunlight
Procedures • Buy 2 of the same type of flowers • Put 12 cm for each cup • Put 1 flower in each cup • Give each flower 100 mm of water each day • Put 1 flower in sun for 1 hour • Put one flower under lamp for 1 hour • Take flowers out of light • Put them in a room temperature room overnight
Photos Soil measured Flower under lamp. Flower under sun
Data/ObservationsAnalyzes 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.
