Observations
• An observation is the gathering of information by using our five senses:
Sight

Observations
• An observation is the gathering of information by using our five senses:
Smell

Observations
• An observation is the gathering of information by using our five senses:
Touch
![Page 8: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/8.jpg)
Observations
There are two types of observations
Qualitative
Quantitative
![Page 9: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/9.jpg)
Quantitative Observations
• Quantitative observations measure what we observe.
• “Quantitative” = quantity (numerical)
![Page 10: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/10.jpg)
Quantitative Observations
• These observations use numbers to measure something in a quantitative way.
• Example: The flower has seven petals.
• Example: You have 8 new emails.
![Page 11: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/11.jpg)
Qualitative Observations
• Qualitative observations describe what we observe.
• “Qualitative” = quality (descriptive)
![Page 12: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/12.jpg)
Qualitative Observations
• These observations use adjectives to describe something.
• Example: The flower has white petals.
• Example: The lemon tastes sour
![Page 13: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/13.jpg)
Which is better?
• Both types of observations are valuable in science.
• Qualitative: The road is long. (describes)
• Quantitative: The road is 5 km long. (measures)
![Page 14: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/14.jpg)
Which is better?
• Sometimes scientists need to quantify qualitative observations.
• For example, someone might say that a dead fish is smelly.
• It is hard to know just how smelly the fish is though.
![Page 15: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/15.jpg)
Which is better?
• To make this quantitative, the scientist could ask the person to rate the “smelliness” on a scale of 1-5.
• This would then allow you to compare how smelly the fish is!
![Page 16: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/16.jpg)

Qualitative or Quantitative?• There are 15 flowers with
white petals
• The email is long
• The surface feels rough
• The leaf is 9 cm long

Qualitative vs Quantitative Observations
Individual Activity

Inferences
• When you explain or interpret the things you observe, you are inferring, or making an inference.
• They are based on reasoning from what you already know
![Page 20: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/20.jpg)
Inferences
• Inferences are often changed when new observations are made.
•Observations are information we gather directly through our five senses….Inferences help explain those observations!
![Page 21: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/21.jpg)
Here are some examples!
• Observation: The grass on the school’s front lawn is wet.
• Possible inferences:It rained.The sprinkler was on.There is dew on the grass
from the morning.A dog urinated on the grass!
![Page 22: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/22.jpg)
Here are some examples!
• Observation: The school fire alarm is going off.
• Possible inferences:
The school is on fire.We are having a fire drill.A student pulled the fire
alarm.

Last one!
• Observation: A student is sitting in the main office.
• Possible inferences:
?Why might a student be
sitting there?

Predicting
• Making a forecast of what will happen in the future based on past experience or evidence
![Page 28: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/28.jpg)
Predicting
• Inferences are attempts to explain what is happening or has happened
• Predictions are forecasts of what will happen
![Page 29: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/29.jpg)
Predicting

Classifying• The process of grouping
together items that are alike in some way
![Page 32: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/32.jpg)
Classifying
• Helps you stay organized
• Organizing a notebook by subject and date helps you find things later
![Page 33: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/33.jpg)
Classifying
• Classifying complex behaviors makes it easier to study and compare

Making Models
• Involves creating representations of complex objects or processes
• Models help people study and understand things that are complex or that can’t be observed directly
![Page 35: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/35.jpg)
Examples of Models• Globes
• Movie sets
• Maps
• Computer models
• Diagrams
• Charts
• Pictures
![Page 36: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/36.jpg)
Making Models
• Models are only representations of a real object or process
• An object or process may be represented by many different types of models
• Some information may be missing from a model
![Page 37: Thinking Like a Scientist. What are 5 skills scientists use to learn more about the world? Observing Predicting Classifying Making Models Inferring.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649ed15503460f94bdf996/html5/thumbnails/37.jpg)
Examples of Models• A model that traces a chimp’s travel
over the course of 1 day
