November 18, 2013 ~ The extra lighting seemed to work, the plants grew quite well in the last week! This week we discussed the needs of plants ~ light, food, water, air, etc. and were curious as to what might happen if one of these needs was altered. We know that as seasons change, the amount of daylight changes. We know how it affects us...it gets dark earlier, so we have to go to bed earlier, right? We have decided to use the scientific method to investigate this seasonal change for plants.
QUESTION: Do plants really need light to survive?
HYPOTHESIS: Plants need SOME light to survive.
THE EXPERIMENT: To test our hypothesis we have taken the remaining plants and divided up.
Group 1 will receive light 24 hours a day.
Group 2 will receive the normal day/night light.
Group 3 will receive NO light.
Each week we will measure: the height of the plant, length of the roots, number of leaves and size of the biggest leaf.
