Scientific Method

Scientific Method • a method of research in which a problem is identified, relevant data are gathered, a hypothesis is formulated from these data, and the hypothesis is empirically tested.

Step 1: Ask a question • Will the plant grow with no sunlight?

Step 2: Form a Hypothesis

Hypothesis • An educated guess • What do you think is going to happen based on what you already know? • What do you know about plants? • Where do they grow?

Will the plant grow with no sunlight? • HYPOTHESIS: • The plant will NOT grow, as it should without sunlight.

Step 3: Conduct an experiment • One plant in sunlight • One plant with no sunlight

Step 4: Analyze the results • What happened to each plant? • Give details throughout the experiment Day 1 : one plant was put in sunlight, one plant was placed in darkness. Day 2: Both plants grew an inch. Day 3: The plant in the sun grew 4 inches, the plant in the dark did not grow. Day 4: The plant in the sun grew 7 inches, the plant in the dark grew 1 inch. Day 5: The plant in the sun grew 1 foot. The plant in darkness grew 2 inches.

Step 5: Conclusion • What were the end results? • Was your hypothesis correct? The plant that was given sunlight thrived. It grew a foot in 5 days. The plant that was not given sunlight only grew 2 inches in 5 days. It did not thrive. The hypothesis was correct. The plant did not grow as well as the plant that was given sunlight.
