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 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 1.Buy 2 of the same type of flowers 2.Put 12 cm for each cup 3.Put 1 flower in each cup 4.Give each flower 100 mm of water each day 5.Put 1 flower in sun for 1 hour 6.Put one flower under lamp for 1 hour 7.Take flowers out of light 8.Put them in a room temperature room overnight

Photos Flower under lamp. Flower under sun Soil measured

Data/Observations Analyzes As you can see the 2 nd flower grew more. They started out at different heights but the 2 nd 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.
