What is a hypothesis?

• Any item, or factor, or condition that can be controlled or changed

• gathering information on a topic using our five senses. Examples: see, hear, taste, touch, and smell

• a good question to be answered

• analyzing the results

What is the correct order of the scientific method?

• Draw a conclusion, form a hypothesis, analyze results (data), ask a question, research, experiment plan, draw a conclusion

• Analyze results (data), draw a conclusion, form a hypothesis, ask a question, experiment plan, research

• Ask a question, research, form a hypothesis, experiment plan, analyze results (data), draw a conclusion

• Experiment plan, draw a conclusion, ask a question, form a hypothesis, analyze results (data), research

What is done in the results (analyzing data) step of the scientific method?

• using the data collected during the experiment that can used for planning and reasoning

• gathering information on a topic using our five senses. Examples see, hear, taste, touch, and smell

• gather information to help make a hypothesis

• Final step or process explaining if the hypothesis was correct
