1. Unit 1: Chemical Building Blocks Chapter 1: Introduction to Physical Science
Big Idea: Scientists investigate the natural world by posing questions, developing hypotheses, designing experiments, analyzing data, drawing conclusions, & communicating results

2. 6 Sections What is Physical Science? Scientific Inquiry Measurement
Math & Science
Graphs in Science
Science Lab Safety
Mrs. Lee - Ch 1

3. Sec 1: What is Physical Science?
KEY CONCEPTS
Scientists use the skills of observing, inferring, & predicting to learn about the natural world
Physical science is the study of matter & energy, & the changes that they undergo
Mrs. Lee - Ch 1

4. Sec 1: Key Terms Science Observing Inferring Predicting Chemistry
Physics
Mrs. Lee - Ch 1

5. Sec 2: Scientific Inquiry
KEY CONCEPTS
Processes used in inquiry include posing questions, developing hypotheses, designing experiments, collecting & interpreting data, drawing conclusions, & communicating
Scientists use models & develop laws & theories to increase people’s understanding of the natural world
Mrs. Lee - Ch 1

6. Sec 2: Key Terms Scientific inquiry Hypothesis Parameter
Manipulated variable
Responding variable
Controlled experiment
Data
Communicating
Model
Scientific theory
Scientific law
Mrs. Lee - Ch 1

7. Sec 3: Measurement KEY CONCEPTS
Using SI allows scientists to compare data & communicate with each other about results
SI units include: m, kg, m3, kg/m3, s, & K
Mrs. Lee - Ch 1

8. Sec 3: Key Terms SI Weight Mass Volume Meniscus Density Celsius scale
Kelvin scale
Absolute zero
Mrs. Lee - Ch 1

9. Sec 4: Math & Science KEY CONCEPTS
When collecting data & making measurements, scientists use math skills involving estimation, accuracy & reproducibility, significant figures, & precision
Mrs. Lee - Ch 1

10. Sec 4: Key Terms Estimate Accuracy Reproducibility Significant figures
Precision
Mrs. Lee - Ch 1

11. Sec 5: Graphs in Science KEY CONCEPTS
Line graphs are used to display data to see how one variable (the responding variable) changes in response to another variable (the manipulated variable)
A line of best fit emphasizes the overall trend shown by all the data taken as a whole
Mrs. Lee - Ch 1

12. Sec 5: Graphs in Science (cont’d)
KEY CONCEPTS (cont’d)
Slope = Rise = y2 – y1
Run x2 – x1
Line graphs are powerful tools in science because they allow you to identify trends & make predictions
Mrs. Lee - Ch 1

13. Sec 5: Key Terms Graph Horizontal axis Vertical axis Origin Coordinate
Data point
Line of best fit
Linear graph
Slope
Nonlinear graph
Mrs. Lee - Ch 1

14. Sec 6: Science Lab Safety
KEY CONCEPTS
Good preparation helps you stay safe when doing science activities in the lab or the field
When any accident occurs, no matter how minor, notify your teacher immediately. Then listen to your teacher’s directions & carry them out quickly
Mrs. Lee - Ch 1
