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.

Thinking Map 1)? 2)? 3)? 4)? Sequence Map Observe Infer Predict Research Research your prediction (internet, books, etc) State the Facts What is Happening in the picture? What will happen next?

Teams or Alone? Brainstorm: Possible Answer: 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

Day 2

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

Scientific Tools 1) 3) 5) 7 2) 4) 6)

Balance Measures Mass (the amount of matter in an object)

Scientific Tools 1) Balance 3) 5) 7 Measures Mass 2) 4) 6)

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 Ask a Questions Form a Hypothesis Design an Experiment Identify Variables (thing you are testing) Collect and Record Data 1st in a chart 2nd put in a graph Draw a Conclusion Communicate Results Repeat at least 3 times

Variables In all experiments we have variables Variable are things that change throughout an experiment

Brace Map 1) Variables 2) 3)

Types of Variables Independent Dependent Controlled What are you testing/changing in an experiment Dependent Data Information you record into your data table Controlled 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 1) 2) 3) 4)

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 1) 2-D Model 2) 3) 4) 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
