 * Research topic: How do different colors of light effect plant growth and plant pigment levels in leaves?**


 * Entity**: What type of plant can be used that will be effected by light? How do i care for this plant in controlled environment?
 * Constants:** temperature, water given, amount of soil, nutrients in soil, amount of exposure to light,
 * Independent variable**: How does changing the color of light a plant is exposed to affect their growth and pigmentation?
 * Dependent variable**: How do I measure the affects of light on plant growth and pigmentation?

1. How will the different colors light effect the width of leaves? Will different sides of the visual spectrum affect growth more? 2. Will the different colors of light give off a different amount heat, also affect plant growth? 3. What different types pigments are there within plant leaves and what causes changes in the amount of these pigments? 4. How do you measure pigmentation in plants? (chromotography?) 5. What type of plant would be best for this experiment and how to care for this plant in a controlled environment?
 * Research questions:**

Looks Good! Get taking notes! 9/23

color of the light || __Background Questions__:
 * Research Design:**
 * __Independent variable__:
 * What light does a plant grow best at?
 * Will the pigmentation of the plant change due to exposure of different light?
 * Can I use chromatography to see a change in the pigmentation?
 * What type of plant would work best?
 * How will i change the color of the light?
 * How will i keep all other light away from the plants?
 * How will i maintain a constant atmosphere? ||
 * __Dependent variable__:

__Quantitative__: width of the leaf __Qualitative__: visible color of plant pigmentation- chromotography || __Constants__:
 * temp
 * amount of oxygen exposed to
 * nutrient in the soil
 * amount of soil present
 * amount of time exposed to light.
 * absence of outside light.
 * same size apparatus plant is in.
 * same wattage of light bulb ||
 * Experimental groups and Control groups || * plant 1: white light
 * plant 2: red light
 * plant 3: blue light
 * plant 4: green light
 * plant 5: no light
