Unit One Vocabulary and Notes
All the Key Terms (Vocabulary) for Unit 1 Science and Technology
Chapter 1, Section 1:Thinking Like a Scientist
2. Qualitative Observation
3. Quantitative Observation
7. Making Models
10. Bold Sentence 1: Scientists use skill such as observing, inferring, predicting, classifying, and making models to learn more about the world.
11. Bold Sentence 2: Successful scientists possess certain important attitudes, or habits of mind, including curiosity, honesty, open-mindedness, skepticism, and creativity.
Chapter 1, Section 2: Scientific Inquiry
1. Scientific Inquiry
4. Independent (Manipulated) Variable
5. Dependent (Responding) Variable
6. Controlled Experiment
7. Operational Definition
10. Scientific Theory
11. Scientific Law
12. Bold Sentence 1: Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence they gather.
13. Bold Sentence 2: In science, a hypothesis must be testable. This means that researchers must be able to carry out investigations and gather evidence that will either support or disprove the hypothesis.
14. Bold Sentence 3: Unlike a theory, a scientific law describes an observed pattern in nature without attempting to explain it. It has been proven true and can be verified.
Chapter 1, Section 3:Why Study Science?
1. Scientific Literacy
2. Bold Sentence 1: Being able to understand scientific principles and think scientifically can help you solve problems and answer many questions in your everyday life?
3. Bold Sentence 2: By having scientific literacy, you will be able to identify good sources of scientific information, evaluate them for accuracy, and apply the knowledge to questions or problems in your life.
Chapter 1, Section 4:Careers in Science
1. Life Science
2. Physical Science
3. Earth and Space Science
4. Bold Sentence 1: The three main branches of science are earth and space science, physical science, and life science.
5. Bold Sentence 2: Although it is convenient to think of science as divided into three branches, these areas are not really separate at all. Most scientific questions being investigated today span the different fields of science.
Chapter 2, Section 1:Measurement - A Common Language
1. Metric System
8. Using SI as the standard system of measurement allows scientists to compare data and communicate with each other about their results.
9. The basic unit of length in the SI system is the meter (m).
10. The basic unit of mass in the SI system is the kilogram (kg).
11. For solids with larger volumes, scientists use the SI unit known as the cubic meter (m3).
12. Density = Mass divided by Volume
13. Because density is actually made up of two other measurements - mass and volume - an object's density is expressed as a combination of two units. Example: g/mL
14. The second (s) is the SI unit used to measure time.
15. In addition to the Celsius scale, scientists sometimes use another temperature scale, called the Kelvin scale. In fact, the kelvin (K) is the official SI unit for temperature.
16. To convert one measurement to another, you need to know the appropriate conversion factor. A conversion factor is an equation that shows how two units of measurements are related.
Chapter 2, Section 4:Safety in the Science Laboratory
1. Good preparation helps you stay safe when doing science activities in the laboratory.
2. Just as in the laboratory, good preparation helps you stay safe when doing science activities in the field.
3. When any accident occurs, no matter how minor, notify your teacher immediately. Then, listen to your teacher's directions and carry them out quickly.
