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

BrainPop: Measuring Matter
Visit the science lab with Tim and Moby to measure an object's length, volume, area, weight, and density in this BrainPOP movie.

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.

BIG IDEA:

Changes in matter are accompanied by changes in energy.

Essential Question: Why are changes in matter accompanied by changes in energy?

Concepts:

Matter exists naturally in 3 states on earth: solid, liquid, and gas.

Changes in temperature are accompanied by changes in kinetic energy which can result in changes in the states of matter.

Changes in matter can be chemical, physical, or nuclear.

According to the law of conservation of mass, a chemical change can be represented by a balanced chemical equation.

Factors that can affect the rate of a chemical change include temperature, concentration, nature of the reactant, and catalyst.

Competencies:

Conduct simple and safe, inquiry-based investigations to observe endothermic and exothermic chemical reactions, measure temperature, volume, and mass, and form conclusions based on experimental evidence.

What is the simplest way of explaining what atoms, elements, compounds and mixtures are?

http://education.jlab.org/qa/atom_02.html

2.1 Classifying Matter

2.1.1 Classify pure substances as elements or compounds

2.1.2 Describe the characteristics of an element and the symbols used to identify elements

2.1.3 Describe the characteristics of a compound

2.1.4 Distinguish pure substances from mixtures

2.1.5 Classify mixtures as heterogeneous or homogenous

2.1.6 Classify mixtures as solutions, suspensions, or colloids

  • Every sample of a given substance has the same properties because a substance has a fixed uniform composition.
  • An element has a fixed composition because it contains only one type of atom.
  • A compound always contains two or more elements joined in a fixed proportion.
  • The properties of a mixture can vary because the composition of a mixture is not fixed.
  • Based on the size of its largest particles, a mixture can be classified as a solution, a suspension, or a colloid.

pure substance – matter that always has exactly the same composition; an element or compound

element – a substance that cannot be broken down into simpler substances

atom – the smallest particle of an element

compound – a substance that is made from two or more simpler substances and can be broken down into those simpler substances

heterogeneous mixture – a type of mixture in which the parts of the mixture are noticeably different from one another

homogenous mixture – a type of mixture in which the substances are so evenly distributed that it is difficult to distinguish one substance in the mixture from another

solution – a mixture that forms when substances dissolve and form a homogeneous mixture

suspension – a heterogeneous mixture that separates into layers over time

colloid – a mixture that contains some particles that are intermediate in size between the small particles in a solution and the larger particles in a suspension

Day 2

Brightstorm:  Matter - Elements and Compounds (2:29)

Elements and compounds are differentiated by their composition. Elements cannot be decomposed into simpler substances. Compounds are composed of two or more elements, but the chemical identities and properties of these elements change when they form a compound. Mixtures on the other hand are composed of elements which retain their chemical identities.

Brightstorm:  Matter - Mixtures (2:37)

Mixtures are composed of pure substances and elements, but unlike compounds these substances retain their own chemical identities and properties. Mixtures can be homogeneous or heterogeneous. Homogeneous mixtures are the same throughout and are called solutions. Heterogeneous mixtures don’t have uniform composition.

2.2.4 Describe methods used to separate mixtures

2.2.5 Describe evidence that indicates a physical change is taking place

  • Viscosity, conductivity, malleability, hardness, melting point, boiling point, & density are examples of physical properties.
  • Physical properties are used to identify a material or choose a material for a specific purpose, or to separate the substances in a mixture.
  • Filtration and distillation are two common separation methods

physical property – any characteristic of a material that can be observed or measured without changing the composition of the substances in the material

viscosity – the tendency of a liquid to keep from flowing; resistance to flowing

conductivity – a material’s ability to allow heat or electric charges to flow

malleability – the ability of a solid to be hammered without shattering

melting point – the temperature at which a substance changes from a solid to a liquid

boiling point – the temperature at which a substance boils; the temperature at which vapor pressure is equal to atmospheric pressure

filtration – the process that separates materials based on the size of their particles

distillation – the process that separates the substances in a solution based on their boiling points

physical change – a change that occurs when some properties of a material change, but the substance in the material stay the same

Day 5

Brightstorm:  Matter - Physical Matter Properties - Chemical Matter Properties (2:58)

Physical matter properties include color, odor, density, melting point, boiling point and hardness. Physical properties are divided into intensive and extensive properties. Intensive properties are used to identify a substance and do not depend upon the amount of substance (density). Extensive properties depend on the quantity of the substance (mass, volume). Chemical matter properties include flammability and reactivity.

Brightstorm:  Matter - Changes in Matter (1:15)

Changes in matter can be classified as either physical or chemical, like matter properties. Physical changes include changes in physical appearance but not composition. All changes in state of matter are physical changes. Chemical changes involve changes in chemical composition and require chemical reactions.

Brightstorm:  Matter - Conservation of Mass (2:29)

The law of conservation of mass states that mass is neither created nor destroyed. In a closed system, mass of reactants is equal to mass of products. The law of conservation of mass is related to the law of conservation of matter.

Brightstorm:  Matter - Law of Definite Proportions - Law of Multiple Proportions (5:05)

The law of definite proportions, also known law of definite composition, states that regardless of the amount, a pure compound always contains the same elements in the same proportions by mass. Law of multiple proportions, also known as Dalton’s Law, states that when one element combines with another to form more than one compound, the mass rations of the elements in the compounds are simple whole numbers of each other.

2.3.2 Describe clues that indicate that a chemical change is taking place

2.3.3 Distinguish chemical changes from physical changes

  • Chemical properties can be observed only when the substances in a sample of matter are changing into different substances.
  • Three common types of evidence for a chemical change are a change in color, the production of a gas, and the formation of a precipitate
  • When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, the composition of the matter remains the same.

chemical property – any property that produces a change in the composition of matter

flammability – a material’s ability to burn in the presence of oxygen

reactivity – the property that describes how readily a substance combines chemically with other substances

chemical change – change that occurs when a substance reacts and forms one or more new substances

precipitate – a solid that forms and separates from a liquid mixture
