PracticingScience What is Science?
Scientists at Work 1. Look/watch things with a purpose 2. Think ahead about what might happen 3. Use tools to make precise or specific information with numbers 4. Put things into definite categories by common properties 5. Use reasoning to draw conclusions 6. Describe and share information with others Process Skills: Observe Predict Measure Classify Infer Communicate
How do Scientists get precise or specific size information about objects? Scientists use measurement tools to make observations that involve numbers or quantities. Scientists at Work: Measurement Stations
How do Scientists Make Observations? Scientists at Work – They… • look closely at something • use any of their five senses to • collect information • make qualitative observations • use measurement tools to collect information • make quantitative observations
Scientists at Work: Making Observations Lab
Making Observations Lab Reflection Questions • Which of the senses was best for making observations about the candy? Explain your answer. • Is the sense listed above always the best one to use? Why or why not? Give reasons to support what you think. • Use evidence to explain why using tools to make observations is useful to scientists. • Based on your observations, write at least three new questions you could ask about the candy.
Scientists at Work: What do you see when you observe the apple? • Write in your notebook. Look over your list. Are they all observations? Remember, observations use the senses to gather information. Is there anything on the list that is what you think or infer?
ObservationsCompare and Contrast Senses Inferences Observation Inferences To infer is to use observations to reach a conclusion based on evidence. Opinion A personal belief that does not need proof. To observe is to look closely at something using any of the five senses and/or measurement tools.
Observations Versus Inferences Make Five Observations Make Five Inferences
Scientists at Work: Write one observation, one inference and one opinion about what you see in the photo.
Scientists at Work: Classify Objects Look at the shells in this photograph. What are some ways you could group them by their properties?
Classify Objects 1. You and a partner get a set of objects. 2. Identify properties they share. 3. Organize them into categories by ways they are similar or related. 4. Share how your classification system with another pair of students. 5. Ask them to infer how you classified the objects. 6. Together, try other ways to classify the objects. 7. Discuss when each method could be useful.
Scientists Communicate in Many Ways List several ways to communicate. What did you write? • Giving talks • Sharing drawing • Making posters • Making charts or graphs • Writing papers or articles • Telephoning • Emailing • Texting • Blogging • Body Language • Using Models • Message boards

Apply Concepts 1. Compare these two animals. List how they look similar and different. 2. Imagine you are on a camping trip. Upon waking up you notice a garbage can tipped over outside your cabin. Plastic bags are torn open. What could you infer?
