Physical Science The study of matter and energy

Physical Science a. Physics: The study of energy and its effects on matter

Physical Science b. Chemistry- the study of the structure of matter and the changes it undergoes due to energy.

Two types of science pure science pure science applied science applied science

Pure Science Studying a subject to learn more about it Studying a subject to learn more about it (Observation)

2 types of Observations: Qualitative observation: describe features of the object (color, shape, smell, etc) Qualitative observation: describe features of the object (color, shape, smell, etc) Quantitative observation: describe an amount of a feature (involves numbers) Quantitative observation: describe an amount of a feature (involves numbers)

Ten Friends by D.L. Rust. Find the missing friend.

Inference: Logical guess based on some evidence.

Infer what season you think it is.

Applied Science (Technology) turning observations into inventions turning observations into inventions Examples: Examples:  cars, eyeglasses, etc. Technology

Turning observations into inferences 1)Take out a piece of notebook paper 2)Write down as many observations about each slide as you can. 3)Make an inference about what you think the next few slide will show.

Measuring w/ a ruler

Theory – a well-tested explanation for observations or results Ex. Theory of how dinosaurs became extinct

Scientific Law – describes an observed pattern in nature Ex. Law of gravity

What does a scientist do? Make Observations Make Observations Ask Questions, Be Curious Ask Questions, Be Curious Solve Problems Solve Problems

The End

Problem Solving or Looking for the answer ?

Solve the Problem (3 steps) 1) Gather Information 1) Gather Information 2) Plan a Strategy 2) Plan a Strategy 3) Make a Prediction 3) Make a Prediction

1) Gather Information Look for any patterns Has anyone else had the problem Have you ever had the problem

2) Plan a Strategy Figure out the potential solutions Can you test the potential solutions one at a time

3) Make a Prediction Keep it simple at first It should be testable
