QUESTION PURPOSE Do colored lights affect the plant’s Do colored lights affect the plant’s growth? growth? Identify what you already know about this topic from previous knowledge. (Alone = minimum of two facts, Pair = minimum of four facts, 3 or more = minimum of 6 facts) FACTS I ALREADY KNOW ABOUT THIS TOPIC FROM PREVIOUS KNOWLEDGE THAT WILL HELP ME KNOW THE POSSIBLE ANSWER TO THIS QUESTION Grass is an easy plant to grow. Different types of water can affect the plants growth. Photosynthesis helps the plants growth. Sometimes the color of light can affect how fast the solar powered car goes. Artificial light is worse than natural light. Temperature can affect the plants growth. *Add more rows as needed. Put one fact in each row. Research additional facts that may give you an idea about what the possible answer to the question is. Include the source where you got the information. (Alone = minimum of two facts, Pair = minimum of four facts, 3 or more = minimum of 6 facts) FACTS I RESEARCHED SOURCE OF INFORMATION THAT WILL HELP ME KNOW THE POSSIBLE ANSWER TO THE QUESTION Does gas affect a http://wiki.answers.com/Q/How_fast_does_oil_and_gasoline_affect_plant_growth plant’s growth? Does the type of soil http://www.usc.edu/CSSF/History/2006/Projects/S1619.pdf affect a plant’s growth?

What makes a plant http://www.instructables.com/id/how-to-plant-hanging-upsidedown-tomatoes/ grow faster it being upside down or right side up? Do magnets affect a http://www.wildlifegardeners.org/forum/tips-tricks-techniques-experiments/4917-canplant’s growth? magnets-affect-plant-growth.html Science Fair 2010 Grades 7-8 *Add more rows as needed. Put one fact in each row. 5. Describe all the possible outcomes that could occur in your experiment. POSSIBLE OUTCOMES THAT COULD OCCUR IN THE EXPERIMENT If I find that colored light affects its growth, then I know the answer to the question is it does affect its growth. If I find that colored lights don’t affect plants growth, then I know the answer to the question is it doesn’t affect its growth. If I find that the temp of light affects its growth, then I know the answer to the question is it affects its growth. *Add more rows as needed. Put one possible outcome in each row. 6. State your hypothesis by choosing one of the possible outcomes from # 5. HYPOTHESIS I think that I will find that the colored lights affect the plant growth, therefore the answer to the question will be that red colored lights do affect the plants growth more then blue, green, and yellowed colored lights.. 7. List several reasons that support the hypothesis that you made in # 6. Get these from # 2, 3, 4. (Alone = minimum of reasons facts, Pair = minimum of four reasons, 3 or more = minimum of 6 reasons) REASONS THAT SUPPORT SOURCE OF REASON THE HYPOTHESIS I CHOSE Different types of water can Previous knowledge affect the plants growth. Does the type of soil affect http://www.usc.edu/CSSF/History/2006/Projects/S1619.pdf a plant’s growth?
