12. Section 1: Thinking Like a Scientist
What skills do scientists use to learn about the world?

13. Thinking Like a Scientist
Observing By patiently observing chimpanzees, Jane Goodall learned
many things using her senses about chimpanzee behavior.
Inferring When you explain or interpret your observations, you are making an inference.
Classifying
Field notes like these contain many details about a chimp’s daily activities.
Prediction Predictions are forecasts of what will happen next.
ccc

14. Making Models
Making models involves creating representations of complex objects or processes. This model traces a chimp’s journey through the forest.

15. Scale Models
A model that has accurate proportions to its parts!

17. Section 2: The Study of Life
How are the branches of life science related?
What are some big ideas in life science?

18. Branches of Life Science
Though life science can be divided into branches,
the different fields of study often overlap.

19. BIG IDEAS IN LIFE SCIENCE!!
Organisms are diverse, yet share some characteristics.
Groups of organisms change over time.
The structure and function of organisms are complementary (work together).
Organisms operate on the same physical qualities as the natural world.

22. Section 3: Scientific Inquiry
What is scientific inquiry?
What makes a hypothesis testable?

23. The Nature of Inquiry
There is no set path that a scientific inquiry must follow.
Pose Questions
Form a Hypothesis
Communicate
Design an Experiment
Draw Conclusions
Collect and Interpret Data

24. What makes a Hypothesis testable???
You have to have a variable: factors that are changed in the experiment.
The factor that is purposely changed is the manipulated variable.
The factor that may change in response to the manipulated variable is the responding variable.
You can only manipulate one variable at a time for the experiment to be CONTROLLED.

25. Collecting and Interpreting Data
A data table helps you organize the information you collect in an experiment. Graphing the data may reveal any patterns in your data.

26. Control Group
After you get your data, to see if your hypothesis was correct, you must compare your results to a group that no variable was added called the control group.

29. Section 4: Safety in the Laboratory
Why is preparation important when carrying out scientific investigations in the lab and in the field?
What should you do if an accident occurs?

30. Safety in the Lab
These safety symbols remind you to work carefully when performing labs in this textbook series. Make sure you are familiar with each safety symbol and what it means.

31. In Case of an Accident
When any accident occurs, no matter how minor, notify your teacher immediately. Then listen to your teacher’s directions and carry them out quickly.
