Florida Benchmarks
SC.5.N.1.1 Define a problem, use appropriate reference materials to support scientific understanding, plan and carry out scientific investigations of various types such as: systematic observations, experiments requiring the identificiation of variables, collecting and organizing data, interpreting data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions.
SC.5.N.1.2 Explain the difference between an experiment and other types of scientific investigation.

3. Unit 1 Lesson 3 What Are Some Types of Investigations?
Florida Benchmarks
SC.5.N.1.3 Recognize and explain the need for repeated experimental trials.
SC.5.N.1.4 Identify a control group and explain its importance in an experiment.
SC.5.N.1.5 Recognize and explain that authentic scientific investigation frequently does not parallel the steps of “the scientific method.”

4. A Process for Science Start with a Question
Unit 1 Lesson 3 What Are Some Types of Investigations?
A Process for Science
Start with a Question
A scientific investigation always begins with a question.
Scientists observe the world and then ask good questions based on their observations.

5. Unit 1 Lesson 3 What Are Some Types of Investigations?
Plan an Investigation
Scientific methods are ways that scientists perform investigations.
Investigations can be planned once a scientist has a testable question.
There are different scientific methods for investigating the world.

6. Investigations Differ
Unit 1 Lesson 3 What Are Some Types of Investigations?
Investigations Differ
The method a scientist uses to conduct an investigation depends on the question being investigated.
An investigation in which all of the conditions are controlled is called an experiment.

7. Investigations Differ
Unit 1 Lesson 3 What Are Some Types of Investigations?
Investigations Differ
Scientists use models to represent real objects or processes.
Repeated observations allow scientists to study processes in nature that they can observe but can’t control.

8. Unit 1 Lesson 3 What Are Some Types of Investigations?
Drawing Conclusions
Whatever scientific methods are used, scientists will have results they can use to draw conclusions.
Conclusions may answer the question a scientist asked before they began.
Conclusions may also point to new questions and ideas for more investigations.

9. Explosive Observations
Unit 1 Lesson 3 What Are Some Types of Investigations?
Explosive Observations
Some science questions are too big, too far away, or too uncontrollable for experiments.
These science questions can only be answered by making repeated observations.
Observations can be used to predict a future event.

Explosive Observations
How do scientists predict the locations for future volcanic eruptions?

11. Super Models When Modeling Is Needed
Unit 1 Lesson 3 What Are Some Types of Investigations?
Super Models
When Modeling Is Needed
Models are used when scientists cannot experiment with the real object or event.
The better a model represents the real thing, the more useful it is.

12. Unit 1 Lesson 3 What Are Some Types of Investigations?
Types of Models
Physical models can be created to simulate a real object or event.
Computer simulation models can be used to see what might happen in the future or to guess what happened in the past.
Diagrams and flowcharts are two-dimensional models used to show how ideas are related.

13. How to Excel in Experimentation
Unit 1 Lesson 3 What Are Some Types of Investigations?
How to Excel in Experimentation
Ask Questions
Scientific questions can be answered by doing experiments. An experiment is a procedure used to test a hypothesis.
It is a good idea to make some observations before stating a hypothesis.

14. Unit 1 Lesson 3 What Are Some Types of Investigations?
Hypothesize
A hypothesis is a statement that can be tested and explains what can happen in an investigation.
Thinking about what you already know, talking to other people, and doing research can help you form a hypothesis.

15. Unit 1 Lesson 3 What Are Some Types of Investigations?
Design an Experiment
Experiments can have two or more setups for comparing results.
Variables are any condition in an experiment that can be changed. Only one variable is tested.
The control is the setup to which all other setups will be compared.

16. Carry Out the Procedure
Unit 1 Lesson 3 What Are Some Types of Investigations?
Carry Out the Procedure
A procedure is the steps a scientist follows in an experiment.
Procedures are often repeated.
By repeating procedures, scientists will have more evidence to support their conclusions.

17. Record and Analyze Data
Unit 1 Lesson 3 What Are Some Types of Investigations?
Record and Analyze Data
Recording data correctly is important. There are many ways to record data.
Once data are recorded, you can analyze the results to draw conclusions.

18. Draw Conclusions and Evaluate the Hypothesis
Unit 1 Lesson 3 What Are Some Types of Investigations?
Draw Conclusions and Evaluate the Hypothesis
All conclusions must be supported with evidence.
The more evidence you have, the stronger your conclusion.
Evaluate your hypothesis after you have reached a conclusion.

19. Draw Conclusions and Evaluate the Hypothesis
Unit 1 Lesson 3 What Are Some Types of Investigations?
Draw Conclusions and Evaluate the Hypothesis
Once you have drawn conclusions, decide if the hypothesis is supported or not.
Scientists build on what they learn by rethinking their hypothesis or designing new experiments.
