Practicing Science
What is Science?
![Page 3: Grade 4 Nature of Science Big Idea 1: The Practice of Science](https://reader035.vdocuments.us/reader035/viewer/2022081604/56816231550346895dd265f4/html5/thumbnails/3.jpg)
WHAT DO ALL SCIENTISTS DO?
![Page 4: Grade 4 Nature of Science Big Idea 1: The Practice of Science](https://reader035.vdocuments.us/reader035/viewer/2022081604/56816231550346895dd265f4/html5/thumbnails/4.jpg)
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

Scientists at Work
![Page 5: Grade 4 Nature of Science Big Idea 1: The Practice of Science](https://reader035.vdocuments.us/reader035/viewer/2022081604/56816231550346895dd265f4/html5/thumbnails/5.jpg)
Scientists use measurement tools to make observations
that involve numbers or quantities.
Scientists at Work: Measurement Stations
How do Scientists get precise or specific size information about
objects?

Scientists Use Measurement Tools
Name of Tool Use of Tool(Quantitative Observation)
Metric Units
Ruler, tape measure, meter stick

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 LabReflection Questions
1. Which of the senses was best for making observations about the candy? Explain your answer.
2. Is the sense listed above always the best one to use? Why or why not? Give reasons to support what you think.3. Use evidence to explain why using tools to make observations is useful to scientists. 4. 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?

Observations
Compare and Contrast Observation
To infer is to use observations to reach a conclusion based on evidence.
OpinionA personal belief that does not need proof.
Inferences
To observe is to look closely at something using any of the five senses and/or measurement tools.
Senses Inferences

Observations Versus Inferences
Make Five Observations Make Five Inferences
![Page 13: Grade 4 Nature of Science Big Idea 1: The Practice of Science](https://reader035.vdocuments.us/reader035/viewer/2022081604/56816231550346895dd265f4/html5/thumbnails/13.jpg)
Scientists at Work: Write one observation, one inference and one opinion
about what you see in the photo.
![Page 14: Grade 4 Nature of Science Big Idea 1: The Practice of Science](https://reader035.vdocuments.us/reader035/viewer/2022081604/56816231550346895dd265f4/html5/thumbnails/14.jpg)
Scientists at Work: Classify Objects
Look at the shells in this photograph. What are some ways you could group them by their properties?
![Page 15: Grade 4 Nature of Science Big Idea 1: The Practice of Science](https://reader035.vdocuments.us/reader035/viewer/2022081604/56816231550346895dd265f4/html5/thumbnails/15.jpg)
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.
Classify Objects

Scientists Communicate
in Many Ways
• Giving talks• Sharing drawing• Making posters• Making charts or graphs• Writing papers or
articles
• Telephoning• Emailing• Texting• Blogging• Body Language• Using Models• Message boards
List several ways to communicate. What did you write?

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?
