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.

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

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
