AIM:
What are Double Line Graphs?
REMEMBER WHEN
we had two plants
Plant 1 received Nitrogen Fertilizer
Plant 2 received none
Plant #1 has the fertilizerGrew to height of2 inches on day 24 inches on day 5
8 inches on day 1010 inches on day 1514 inches on day 20
Plant #2 has NO fertilizerGrew to height of2 inches on day 24 inches on day 5
7 inches on day 108 inches on day 159 inches on day 20
What is Predicting?
Which plant grew better?
How could we analyze our Data?
Would setting up a LINE GRAPH be useful in our analysis?
What do we do first?
Plant #1 Has fertilizer
Grew to height of2 inches on day 24 inches on day 58 inches on day 1010 inches on day 1514 inches on day 20
Plant 2 No fertilizer
Grew to height of2 inches on day 24 inches on day 5
7 inches on day 108 inches on day 159 inches on day 20
