Chapter 1 Science Skills

1.1 What is Science?

1.1.1      Explain how science & technology are related

1.1.2      List the major branches of natural science & describe how they overlap

1.1.3      Describe the main ideas of physical science

  • Science begins with curiosity & often ends with discovery.
  • Science & technology are interdependent. Advance in once lead to advance in the other.
  • Natural science is generally divided into three branches: physical science, Earth & space science, and life science.

science – a system of knowledge about the natural world and the methods used to find that knowledge

technology – the use of scientific knowledge to solve practical problems

chemistry – the study of the composition, structure properties and reactions of matter

physics – the study of matter and energy and the interactions between the two through forces and motion

geology – the study of the origin, history and structure of Earth

astronomy – the study of the universe beyond Earth

biology – the study of life and life processes

Brightstorm: Introduction to ChemistryChemistry Definition (1:56)

Chemistry can be broadly defined as the study of matter and the changes that it undergoes. In Chemistry there are several different branches including organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry and biochemistry.

1.2 Using a Scientific Approach

1.2.1 Describe the steps in a scientific method

1.2.2 Compare & contrast facts, scientific theories, and scientific laws

1.2.3 Explain the importance of models in science

1.2.4 Explain the importance of safety in science

  • The goal of a scientific method is to solve a problem or to better understand an observed event.
  • A scientific law describes an observed pattern in nature without attempting to explain it. The explanation of such a pattern is provided by a scientific theory.
  • Scientific models make it easier to understand things that might be too difficult to be observed directly.

scientific method – an organized plan used for gathering, organizing, and communicating information

observation – information obtained through the senses

hypothesis – a proposed answer to a question

manipulated variable – the variable that causes a change in another variable

responding variable – a variable that changes in response to a chance in the manipulated variable

controlled experiments – an experiment in which only one variable, the manipulated variable, is deliberately changes at a time

scientific theory – a well-tested explanation for a set of observations or experimental results

scientific law – a statement that summarizes a pattern found in nature

model – a representation of an object or event

Brightstorm: Introduction to ChemistryScientific Method Steps (5:17)

The scientific method is a set of guidelines for scientific investigation. It helps us approach all scientific experiments and inquiries methodically and scientifically in order to avoid jumping to conclusions or missing links in a logical chain. The five steps of the scientific method include 1) defining the problem 2) making observations, 3) forming a hypothesis, 4) conducting an experiment and 5) drawing conclusions.

1.3 Measurement

1.3.1 Perform calculations involving scientific notation and conversion factors

1.3.2 Identify the metric & SI units used in science & convert between common metric prefixes

1.3.3 Compare & contrast accuracy and precision

1.3.4 Relate the Celsius, Kelvin, & Fahrenheit temperature scales

  • Scientific notation makes very large or very small numbers easier to work with.
  • Scientists use a set of measuring units called SI.
  • The precision of a calculation is limited by the least precise measurement used in the calculation.

scientific notation – a way of expressing a value as the product of a number between 1 and 10 and a power of 10

length – the straight-line distance between two points

mass – the amount of matter in an object; a measurement of inertia of an object, which depends on the amount of matter the object contains

volume – the amount of space taken up by an object

density – the ratio of a material’s mass to its volume

conversion factor – a ratio of equivalent measurements that is used to convert a quantity from one unit to another

precision – a gauge of how exact a measurement is

significant figures – all the digits in a measurement that are directly measured, plus the last digit, which is estimated

accuracy – the closeness of a measurement to the true value of what is measured

thermometer – an instrument that measures temperature

Brightstorm: Introduction to Chemistry - Scientific Units (3:23)

There are certain unit systems which the scientific community has universally agreed upon. To measure distance in scientific units we use meters (m), to measure mass we use grams (g), to measure volume we use liters (L) and to measure temperature we use either degrees centigrade (C) or degrees Kelvin (K).

Brightstorm: Introduction to Chemistry - Scientific Notation (2:26)

Scientific notation is used to make extremely large or small numbers more manageable. Numbers written in scientific notation are the products of a digit term and an exponential term and are written in the general form a x 10^n. For example, 0.0000234 is written 2.34 x 10^n and 456,000 is written as 4.56 x 10^5.

Brightstorm: Introduction to Chemistry - Significant Figures (6:04)

When working with scientific data, we only want to show as many figures as carry accurate meaning, called significant figures. When adding or subtracting two numbers, we round to the same number of decimal places as the term with the fewest decimal places. When multiplying or dividing numbers we round to the same number of figures as the term with the lowest number of significant figures. In scientific notation, the digit term, not the exponential term counts as significant.

Brightstorm: Introduction to Chemistry - Dimensional Analysis (6:11)

Dimensional analysis, also called the factor/label method, is a method for converting between units using ratios between different unit systems.
