Chapter 1Section 1Thinking Like a Scientistpages #5 – #12.Slide2
Scientists use skills such as:
1. observing2.
inferring3. predicting
4.
classifying and5. making models to learn more about the world.Slide3
OBSERVING
Observing – means using one or more of your senses to gather information. Your senses include sight, hearing, touch, taste and smell. You use your sense daily. For example, if it is chilly in the morning, you’ll probably wear a jacket to school.Slide4
Observations can be either:
Quantitative – deal with a number, or amount.For example, reading 3 e-mails in your inbox is a quantitative observation.
Qualitative
– deal with descriptions that cannot be expressed in numbers.
For example, noticing that a car is green or a lemon tastes sour are both qualitative observations.Slide5
Inferring
Inferring is when you explain or interpret the things you observe, you are inferring, or making an inference.Inferences are based on reasoning from what you already know. Inferences are NOT wild guesses!
For example, if everyone is outside with big coats on you an infer that the weather is cold.Slide6
List 3 inferences about this picture.

PREDICTING
Predicting means making a forecast of what will happen in the future based on past experiences or evidence.Predictions are not always correct.For example, you might predict that the Cleveland Browns
will have a losing record based on previous years.Slide8
Prediction vs. Inference
Predictions and inferences are closely related.
While inferences are attempts to explain what is happening or has
happened, predictions are forecasts of what
will happen.Slide9
Make a prediction based on what you observe from the picture.

CLASSIFYING
Classifying is the process of grouping together items that are alike in some way.Classifying things help you to stay organized so you can easily find and use them later.
For example, you have different drawers in your dresser for socks, shirts and pants.Slide11
Classify the following items:
1. 2. 3.
4.Slide12
MAKING MODELS
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.Computer generated objects and globes are examples of models.Slide13
SCIENTIFIC ATTITUDES
Science is the way of learning about the natural world. Successful scientists posses certain important attitudes including: 1. curiosity
2. honesty 3. open-mindedness 4. skepticism (having an attitude of doubt)
5. creativity.
