My timeline would be when I was born, when I learned how to ride my bike at 6, now I am 9 years old.
I need as much water, sunlight, and nitrogen for my tree.
The teacher is explaining how trees rings indicates a trees growth.
Students, I want you to record how many colors you collected for your tree.
The students compare their own timeline to a trees rings for relativity to the activity.
I only collected one yellow this round.
The "trees" students, will have 30 seconds to collect as much nutrients as they can. The colored paper represents the trees nutrients, blue is water, yellow is sunlight, and green is nitrogen or phosphorous.
If I was a forester my strategy would be to plant the trees further apart from each other.
The students record their data and gets ready to play another round.
In this round, the student realize that there was less nutrients to collect.
Students conclude from their data that when trees are grown close together they are in competition with each other which can affect their tree rings growth.
