Make an Observation/Ask a question 2. Write a Hypothesis 3. Make Predictions 4. Perform Experiments / Data Collection 5. Conclusion Statement Observation1st Step in the Scientific Method Process 1. An observation is something you can see or prove 2. An inference is an opinion, or conclusion, based on observed facts Observation vs. Inference Observation Observation Inference Observation vs. Inference Observation 2. Observation 3. Inference Observation vs. Inference Observation Observation Inference Write a Hypothesis2nd Step in the Scientific Method Process Hypothesis- Possible explanation or answer to a question “What do you think is the answer to your question or the reason for your observation” 3rd Step in the Scientific Method ProcessMake Predictions Prediction Statement of what may happen in the future “What are some if / then statements that explain and confirm your hypothesis” Predictions If the cows are warned a car is coming, then they will stop talking and act like cows. Predictions If………………… then……….. Predictions If………………… then………………… Perform Tests or Experiments4th Step in the Scientific Method Process “What will you do to test your predictions?” -1. Collect Data -2. Find out if your hypothesis is or is not correct. State Your Conclusions5th Step in the Scientific Method Process 1. “What did your experiment show?” 2. “Did your experiment confirm (prove right) your hypothesis?” 3. Application “How does this apply to everyday life?” Science Vocabulary 1. Bias- To influence in an unfair way 2. Analyze- -Consi
