Scientists use various process skills like observation, estimation, measurement, inference, prediction, interpretation, and explanation to study objects and events in science. Some key skills are observing using the 5 senses and tools, estimating and then precisely measuring quantities, inferring conclusions from facts and prior knowledge, and predicting future outcomes based on observations and data. Scientists work together to analyze data and form explanations for natural phenomena like hurricanes.
What skills do scientists use
- 1. Sep 2013 Ch 1 Lesson 2 What skills do scientists ?use
- 3. Scientists use process skills to learn about objects, places, or events. Observation is a process skill. Observe = When you use your five senses to find out about .something
- 4. Your senses include sight hearing touch taste smell
- 6. Scientists often use tools to make observations. A satellite is a tool that helps scientists observe Earth`s .weather
- 8. Data from satellites are often .displayed on weather maps .Hurricanes are strong storms
- 9. Weather map
- 11. Estimat e and Measur e
- 12. Scientists sometimes estimate when they make observations. Estimate to make a careful guess. A scientist might feel the wind pushing hard against his body. He might estimate that the wind is blowing about 70 or 80 kilometers .per hour
- 13. To find the exact wind speed, the scientist would make a measurement. A measurement = a number that tells how much or how many. Scientists often use tools to .measure
- 14. Anemometer is a tool that .measure the speed of the wind
- 15. Infer and Predic t
- 16. Some data and observations are facts. For example,the statement ‘’The wave crashed into the pier’’ fact you can use facts to infer, or .draw a conclusion
- 17. Scientists infer what they think is happening based on: 1 - what they observe (or) 2 - prior knowledge. , For example
- 18. A scientist observing the waves in the picture might infer that a .hurricane is coming on shore
- 21. Observations also can help you to predict. Predict = tell what you think will happen in the future. ,For example
- 22. A scientist might predict that the waves will get bigger as the hurricane . gets closer to shore
- 23. Interpre t and Explain Data
- 24. Scientists work together to interpret their data and form scientific explanations. : :A good explanation uses observations, inferences, prior knowledge, measurements, and . data from an investigation
- 25. Scientists are trying to develop the ability to forecast when .hurricanes will form
- 27. They use: observations weather data their knowledge of past storms to predict where hurricanes will strike and how strong they will .be 123
