Introduction:
The second largest kingdom on our planet is plants. Plants require water, light, CO2. Light is the basis of all plant life, without light plants cannot photosynthesise, obtain energy and reproduce. Within the visible colour spectrum red has the longest wavelength (650nm,) green has a wavelength of 510nm and blue has a wavelength of 475nm. Millions of dollars is spent electrical costs for agricultural purposes. This investigation's purpose is to see which light colour is most …show more content…
By conducting this experiment one could find the most effective light colour for growing plants. This could increase the amount of produce produced by agricultural farms. With more produce less people will die of starvation each year.
Hypothesis:
Subtle changes of light colour can affect the growth and nutritional quality of vegetables.
Variables:
Independent Variable: The Color of the light
Dependent Variable: The Plants growth
Controlled Variables - Temperature - The type of soil -The amount of water the plant receives
Method:
When conducting my experiment I will
Plant four lettuce seedlings in four identical plant pots.
Water them regularly each morning.
Expose Plant A (Control Experiment) to sunlight, expose Plant B to red light, expose Plant C to blue light and expose Plant D to green light.
Over a two week period I will observe and record their height, leaf length and number of leaves each day.
Materials:
4 Lettuce Seedlings, 4 identical plant pots, 3 Lamps with different bulb light colours each.
