Scientific Inquiry
• Scientific Inquiry– It is a process of asking questions and searching
for the answers
![Page 3: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/3.jpg)

1) Observe
• Look at the FACTS
![Page 5: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/5.jpg)
Observations
• We observe the natural world around us.• What is the natural world?– Living Things– Weather – Energy – Forces– Matter – Solar System
![Page 6: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/6.jpg)
2) Infer
• Use past experiences to help interpret the situation
![Page 7: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/7.jpg)
3) Predict
• What will happen next?– Must be a realistic explanation
![Page 8: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/8.jpg)
4) Research
• Before performing an experiment scientist need to study what other scientists have already done (research)
• What can we use?– internet, encyclopedias, books, magazines etc.

Teams or Alone?
• Brainstorm:– What a some advantages and disadvantages of working in
teams or along• Possible Answer:– Alone:
• Ask your own questions• Conduct your own experiments• Draw your own conclusions
– Teams :0)• Each member can work on a different part of the experiment• They work faster• They come up with more ideas

Tools
• Science uses many different tools to help them perform their experiments
![Page 14: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/14.jpg)

Safety First
• Read All Directions• Follows teachers instructions• Keep work area neat and clean• Never taste or smell anything• Use chemicals carefully. Dispose of chemicals according
to teachers directions• Tell the teacher if there is an accident• Wash your hands after a lab• Wear goggles and glove when necessary• Tie long hair back

Scientific Method
• The scientific method is an organized ways to answer questions and solve problems
![Page 27: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/27.jpg)
Steps of the Scientific Method
1. Ask a Questions2. Form a Hypothesis3. Design an Experiment
1. Identify Variables (thing you are testing)
4. Collect and Record Data1. 1st in a chart2. 2nd put in a graph
5. Draw a Conclusion 6. Communicate Results 7. Repeat at least 3 times
![Page 28: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/28.jpg)
Variables
• In all experiments we have variables• Variable are things that change throughout an
experiment
![Page 29: Chapter 1. Scientific Inquiry – It is a process of asking questions and searching for the answers](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e0c5503460f94af4f87/html5/thumbnails/29.jpg)

Types of Variables
1. Independent1. What are you testing/changing in an experiment
2. Dependent1. Data2. Information you record into your data table
3. Controlled 1. Things that are kept the same throughout the
entire experiment

Try It:• Sally wanted to see how high a ball would
bounce when it hit different surfaces. She dropped a ball on a hard wood floor, carpet and tile.
• Independent Variable:– Surface ball hit: Hardwood floor, carpet and tile
• Dependent Variable:– Height ball bounced
• Controlled:– Ball, height dropped from
