Light Intensity

• Fast Plant Project
• By Melissa Gerace
• Julie Anderson

2
Fast Plant Set-up

• High Intensity Light
• 7 plants ( A toG )
• Medium Intensity Light
• 7 plants ( H to N )
• Low Intensity Light
• 7 plants ( O to U )

3
Hypothesis

• The stronger the light intensity the greater the
  plant height will be
• In our experiment the closest plant to the light
  will be the tallest and the plant farthest away
  will be the shortest

4
Light Intensity

• Three groups of Plants

5
Light Intensity

• Three Levels of Light

6
Light Intensity

• Three Growth differences

True Leaf Data

• For this graph we took an average of true leaves
  for each group and our results show a difference
  in the amount of true leaves that support our
  hypothesis

14
Our Results

• To support our hypothesis our results show a
  significant difference of plant height between
  the three groups
• We also found the same results with the number of
  true leaves, meaning that group A had the most
  ,and Group C had the least
• Also, our results show that only one plant from
  group A (high intensity) produced 6 flowers
  and 1 pod.

Anova Results-Plant Height

• Low - Ave7.43 Var1.37
• Med - Ave6.93 Var1.45
• High - Ave11.83 Var13.08
• P-val.0026

16
Anova Results-True Leaves

• Low - Ave1 Var0
• Med - Ave2 Var0
• High - Ave3.16 Var1.36
• P-val.019

17
Conclusions

• Based on our statistical and experimental results
  our original hypothesis proved to be accurate
• The higher the light intensity to the plant, the
  stronger and more productive the growth
