Plants require sunlight, need water to survive, too much sunlight can kill them, if the plants are in an overly populated area the can die, plants that have different colors have different meanings for the colors. We discovered that baking soda and water transform into CO2 aims it can help plant growth. We also learned that you have to be fragile with the plant’s veins. Questions that interest us are can overpopulated areas affect plant growth, and does light quality affect in plant growth? |
Research Question |
Our question is can light quality affect plant growth? People who grow plants inside have to use unnatural lighting. We want to see which type of light is the healthiest for the plant and delivers the quickest progress. |
Predictions |
We know that the plant could be damaged by both lights, and that unnatural light could be a bad idea. If not we know that either LED or Incandescent will deliver the best results. We predict that the LED light will have the safest and most effective growth, this is because LED gives off a safer energy and doesn’t heat up as badly as an incandescent light does. LED is also a lot brighter and could cause a faster affect. |
Experimental Design |
Two cups containing 6cm of baking soda mixed with water. Each cup will receive 10 spinach disks that have had their oxygen extracted from them. Cup one will use an LED lamp and cup two will use an incandescent lamp. Both lamps will be pointed at the same angle. We will check every minute for 15 minutes to see how many spinach disks have risen. |
