Scientific Method Turn to the person sitting next to you and tell them at least one thing you remember about the scientific method!!!
What is the scientific method? The process that is used to find answers to questions about the world around us.
Is there only one “scientific method”? No, there are several versions of the scientific method. Some versions have more steps, while others may have only a few. However, they all begin with the identification of a problem or a question to be answered based on observations of the world around us and provide an organized method for conducting and analyzing an experiment.
What is a hypothesis? It is an educated guess based on observations and your knowledge of the topic.
What is data? It is information gathered during an experiment.
1. Identify the Problem What do you want to know or explain? Use observations you have made to write a question that addresses the problem or topic you want to investigate.
2. Form a Hypothesis What do you think will happen? Predict the answer to your question or the outcome of the experiment.
3. Create an Experiment How will you test your hypothesis? Develop a procedure for a reliable experiment and address safety rules
4. Perform an Experiment Follow the steps in your procedure to perform your experiment Record data and observations
5. Analyze the Data Is the data reliable? Does your data and observations from the experiment support your hypothesis?
6. Communicate the Results Write a conclusion that summarizes the important parts of your experiment and the results
Part 2: Process Skills
What are science process skills? The foundation of the scientific method Six basic skills: • Observation • Inference • Classification • Measurement • Communication • Prediction We will be working on these all year!
Observations and Inferences Look at the drawing. What do you notice and what do you think is going to happen?
Observations and Inferences How does your story change?
Observations and Inferences Did it change again?
Observations and Inferences What do you observe? What do you infer? Compare what you think now to your earlier written accounts.
What is an observation? • When you observe, you become aware of something using one of your senses. • Your five senses are smell, taste, sight, touch, and sound. • In an observation you simply describe something as it appears. • An observation is a statement describing a fact.
Qualitative Observation • Sometimes scientists must make very careful observations. • Often their senses are not good enough. There are some things that cannot be observed using just your senses. (Examples: radiation, sound waves, planets, cells, etc.)
Can you think of ways that scientists have solved this problem? How can scientists extend their senses?
What is an inference? • When you infer, you make a mental judgment based on observations. • Inferences cannot be directly observed. They require thought. • For example, if you get up in the morning, look up at the sky and observe dark clouds, observe the air is cool and humid, and observe puddles on the ground, you might infer that it has recently rained. • Note: you did not see rain; you decided that it rained based on your observations. An inference is a statement based on your interpretation of the facts.
Observations That plant is extremely wilted. The car stopped running The braves are leading their division Inferences That plant is extremely wilted due to a lack of water. The car stopped running because it was out of gas. The braves are leading there division because they are playing well right now. Observation vs. Inference
Observation or Inference?
1 Write one observation. Write one inference
2 Write one observation. Write one inference
3 Write one observation. Write one inference
4 Write one observation. Write one inference
5 Write one observation. Write one inference
6 Write one observation. Write one inference
Question of the Day How can people have different inferences about the same observations.
