Chapter 1
Scientific Inquiry
• Scientific Inquiry– It is a process of asking questions and searching
for the answers
Thinking Map
• Sequence Map
1)? 2)? 3)? 4)?
1) Observe
• Look at the FACTS
Observations
• We observe the natural world around us.• What is the natural world?– Living Things– Weather – Energy – Forces– Matter – Solar System
2) Infer
• Use past experiences to help interpret the situation
3) Predict
• What will happen next?– Must be a realistic explanation
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.

State the Facts
What is Happening
in the picture?
What will happen next?
Research your prediction
(internet, books, 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
Which way is better?Double Bubble
Alone Teams

Tools
• Science uses many different tools to help them perform their experiments

Measures Mass
Graduated Cylinder
• Measures Liquid Volume
Ruler
• Measures Length or Distance
Telescope
• Helps us to see objects far away
Magnifier
• Hand Lenses: Help us see details of objects.• Microscope: Helps us to see objects that are
very small
Thermometer
• Measures Temperature
Computer
• Helps us make models of data.• Helps us to see patterns within data
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

Day 3
Scientific Method
• The scientific method is an organized ways to answer questions and solve problems
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
Variables
• In all experiments we have variables• Variable are things that change throughout an
experiment

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
Day 4
Models
2) 3) 4) 1)
Models
• Scientist use models when they can not test the real thing.
• Exp:• How does wind affect a airplane?– We make a model of a new aircraft and use a wind
tunnel• Path of a Hurricane
Types of Models
• 2 Dimensional Models– Describes something that has length and width – No Height– EXP World Map, House floor plans
Models
2) 3) 4) 1) 2-D Model
Shows Length and Width
EXP: Map or House Plans
Types of Models
• 3 Dimensional Model– Describe objects that have length, width and
height– EXP: Globe
Types of Models
• Computer Model– Takes a lot of data and puts it into a model– Exp: path of a hurricane or strength of storms
