The document outlines the scientific method process of conducting an experiment. It discusses forming a research question about how fertilizer influences plant growth and generating a hypothesis. An experiment is proposed that tests different amounts of fertilizer as the independent variable on plant growth as the dependent variable, while controlling other variables like sunlight and temperature. The experiment would collect data on plant growth with different fertilizer amounts and draw a conclusion about how the fertilizer influences plants.

29. DATA INTERPRETATION
EXAMPLE:
The vines of the plant
receiving:
- ½ capful of fertilizer grew
15% longer
- 1 capful of fertilizer grew

30. DATA INTERPRETATION
EXAMPLE:
The vines of the plant
receiving:
- 1 ½ capfuls of fertilizer
grew 50% longer
- 2 capfuls of fertilizer grew

31. DATA INTERPRETATION
EXAMPLE:
The vines of the plant
receiving:
- No capful of fertilizer has
no growth

EXAMPLE:
“Plant poured by brand X
fertilizer helps plant grow
at least 30% taller and be
greener than plants with
