is this a thesis statement?

Question

The effects of different coloured lights on bean growth are clear light bulb will increase the growth rate of string bean plants more that the red, blue, and yellow light bulbs will.

Answer 1

Try this: The effects of light and bean growth have shown that clear light bulbs increased the growth rate of string bean plants more when compared with red, blue and yellow light bulbs.

Answer 2

Clear light from a light bulb will effect growth of string bean plants more fully than red, blue, or yellow light bulbs.

Answer 3

Yes. But check for grammar. (E.g. insert "that a" after "are" ... replace "more that" with "more than").

Also, consider removing "bulb". It is the color of the light that is affecting the string beans, not the bulbs.

However, if you do, then this gives you something else to test in your experiment. The *only* difference between the four bulbs needs to be the color of the light. Your experiment needs to eliminate the possibility that there is some other difference, such as temperature, between the bulbs. So buy yourself four little baby thermometers (they're cheap) and make sure that the temperature on the surface of the soil is the same for all four plants. This is called "eliminating a variable" (temperature).

Answer 4

Yes, but it looks like you need to edit that sentence a little.

The part where it says, "growth are clear" is problematic.

A simple solution would be to cut out the first part of the sentence and say, "A clear light bulb will increase the growth rate..."

Answer 5

It actually sounds more like a hypothesis, but if you put it at the end of an introductory paragraph you could make an essay out of explianing the statement.
