Step 3 of the scentific method Hypothesis An educated guess because of observation/research (step 1). EX: When a plant does not receive enough light, its growth is stunted.
Step 4 of the scentific method Prediction Formatted using IF-THEN statement. EX: ‘If a plant does not receive enough light, then its growth will be stunted.
Step 5 of the scentific method Experimentation Developing a method so you can test your prediction.
Step 6 of the scentific method Conclusion Accept or reject hypothesis based on experiment. Based on statistical analysis of data.

What is a dependent variable May, or may not be influenced by the independent variable EX: the amount the plant grows
