The experimental group the plant was a lighter green than the control group.
The control group had more leaves than the experiment.
We infer that the experimental group was a lighter color unlike the control group unlike because white light is essential for a plant to create chlorophyll.
Another inference we can make is that the control group had more leaves than the experimental group because it was receiving white light.

What would happen to the plant of the chlorophyll was removed ?
Why is photosynthesis necessary?
The hypothesis was if we put the lentil beans to absorb green light then it will grow shorter than the lentil beans absorbing the white light because white light has more energy
Voice
The hypothesis was NOT supported because the experimental group was taller then the control group.
However, other observations made us realize that the green light was not being absorbed in the EG, the light was reflected. The plants are green, meaning they reflect green light, thus they can't absorb it.

What is the effect of green light on lentil bean plant growth?
if we put the lentil beans to absorb green light then it will grow shorter than the lentil beans absorbing the white light because white light has more energy.
photosynthesis is the process in converting light energy into chemical energy.

A simulation will be shown that models our experiment.
1. In the piece of paper write your hypothesis. "If.. then.. because" format.
2. Choose what colors and type of plant plant you want to use.
3. BEGIN EXPERIMENT

Photosynthesis happens in the chloroplasts.
chlorophyll is what makes the plant green.
Title: Which Color of Light Best Effects the Growth of Radishes?
This experiment I researched helped me make my hypothesis and design the experiment because it showed me that other research has shown that lighter colors increase plant height.
