Unit 1 – Subtopic 1: MATH FOR SCIENCE - Significant Figures - Scientific Notation *** Remember NOTES are in blue!***

SIGNIFICANT FIGURES Look at this table and suggest a definition for significant figures. NUMBER QUANTITY OF SIGNIFICANT FIGURES 0. 000567 123456 86000 35. 079 2001000 3 6 2 5 4

Significant Figures Definition: Numerals that affect the value of a number when written in scientific notation. Rules: � All numerals from 1 -9 are significant. � Zeroes are significant if they are between two significant figures. This is important when doing calculations in science – � Always write your answer based on the component of your problem with the least

Let’s practice: How many significant figures are there in each of these numbers? 1. 2. 3. 4. 5. 3. 461728 4. 091 0. 97001 5. 2631 3. 461728 + 4. 091 + 0. 97001 + 5. 2631 (Solve the problem and then write the answer to the correct number of significant figures) Check your answers at the solution station when you are done then return to your seats.

Let’s practice (your turn!): How many significant figures are there in each of these numbers? 1. 2. 3. 43705 0. 0663 363587. 006 + 433. 12 + 68. 03 (Solve the problem and then write the answer to the correct number of significant figures) Check your answers at the solution station when you are done then return to your seats.

SCIENTIFIC NOTATION How much money would you like to have in your entire lifetime? (Write down that amount in numerals in your notebook. )

Scientific Notation There is an easier way to write very large numbers and very small numbers – they can be written in scientific notation. Scientific notation is expressed in this way: �A x 10 B � Where A is a number greater than or equal to 1 but less than 10. (Therefore it is a number that only has 1 significant figure before the decimal point) B is an exponent of 10. For example: � 0. 0000437 = 4. 37 x 10 -5 � 165, 000, 000 = 1. 65 x 1011

Scientific Notation To change numbers less than 1 to scientific notation: � Move the decimal point to the right until there is only one significant figure in front of the decimal point. This new number will be “A”. � Count the number of places you have moved your decimal point. Place a negative sign in front of this number and make it your exponent of 10 (B). � For example: 0. 0004835 = 4. 835 x 10 -4

Scientific Notation To change numbers greater than 1 to scientific notation: � Move the decimal point to the left until there is only one significant figure in front of the decimal point. This new number will be “A”. � Count the number of places you have moved your decimal point. Make this number your exponent of 10 (B). � For example: 4835000 = 4. 835 x 106

Let’s practice: Write these numbers in scientific notation. 1. 2. 3. 4. 5. 56000 40765 0. 0328 0. 000831 910. 0248

WARM UP – DAY 2 (Do all warm ups for this Unit on the same sheet of paper) What are three guidelines to follow in this class? Why is it sometimes necessary to write numbers in scientific notation? When adding numbers, you should always make sure that your answer has the same amount of significant figures that matches the number with the A. B. smallest / largest significant figures (choose one)

ANNOUNCEMENTS Unit 1 Homework Packet (Part 1) is due next Wednesday 2. 3. 16 You will have a Quiz next Tuesday / Wednesday (depending on how far we get to). You will have a test next Friday / the Monday after that. Turn in the yellow packet (if you haven’t done so already).

Unit 1 – Subtopic 2: THE METRIC SYSTEM - What is the Metric System - Metric Conversions

THE METRIC SYSTEM

The Metric Staircase

The Metric System This is a system used internationally for measuring items. The Metric System relies on base units for every type of measurement that exists. Each measurement can be converted into smaller or larger units by multiplying or dividing by 10 and adding an appropriate prefix to the base unit.

The Metric System Conversions To go from smaller units to larger units, divide by 10 each step of the staircase. � For example: Convert 36000 mm to m. From mm to m, we take 3 steps. Therefore we must divide 36000 by 10, 3 times. 36000/10/10/10 = 36000 / 103 = 36000/1000 = 36 m. To go from larger units to smaller units, multiply by 10 for each step of the staircase. � For example: How many liters are there in 45 k. L? From k. L to L, we take 3 steps. Therefore we must multiply 45 by 10, 3 times. 45 x 10 x 10 = 45 x 103 = 45 x 1000 = 45000 L.

RESEARCH: Work individually or in pairs to prepare a product summarizing the Metric System. You should include: � What is the Metric System? � A mnemonic device to help you remember the Metric System. � What are the metric base units used for each of these types of measurements? Mass, Length, Volume, Time, Pressure, Temperature, Energy � Which metric unit (prefix included) would you use to measure: A Pencil

Unit 1 – Subtopic 3: MATTER - What is Matter? - Types of Matter

MATTER Matter is anything that has mass and takes up space. There are three states of matter: � Solid Particles closely arranged, little kinetic energy Volume and shape are constant. � Liquid Particles loosely arranged, medium kinetic energy Volume is constant, shape varies based on container � Gas Particles very loosely arranged, high kinetic energy Volume and shape vary

CLASSIFICATION OF MATTER Sort these items into four groups. Make sure to give a reason for placing each item into the group you placed it in. � Chocolate chip cookie � Gold � Carbon dioxide � Kool aid � Water � Copper � Air � Soil � Pizza

Classification of Matter Scientists also place items into groups. In Biology, we classify living things into the major kingdoms and then smaller groups. In Chemistry, we classify (sort / group) items based on the type of matter. � Pure Substances Elements Compounds � Mixtures (Impure substances) Homogenous mixtures Heterogeneous mixtures

Classification of Matter Elements – these are made up of one type of atom. They are found on the Periodic Table.

Classification of Matter Compounds – These are made from more than one atom and arranged in a particular formula.

Classification of Matter – Homogeneous Mixtures – These do not have a specific chemical formula, but they look the same throughout.

Classification of Matter – Heterogeneous Mixtures – These do not have a specific formula and may look different from one section to the next.

Classification of Matter Use your notes and this concept map to write 5 sentences about matter. Give definitions of the four major types of matter, and examples of each one.

YOUR TURN Sort these items into the four types of matter. � Chocolate chip cookie � Gold � Carbon dioxide � Kool aid � Water � Copper � Air � Soil � Pizza

Unit 1 – Subtopic 5: BASIC ATOMIC STRUCTURE - What is an atom made of? - Arrangement of Subatomic Particles

History of the Atom How Small is the Atom?

Atomic Structure Atoms are the smallest unit of any element that has all its properties. Atoms have two main sections – the nucleus and the shells. The nucleus contains protons and neutrons. The shells contain electrons.

Atomic Structure Electrons are negatively charged particles. Their mass is negligible (very close to 0). Protons are positively charged particles. They have a mass of 1 atomic mass unit (a. m. u. ). Neutrons are neutral – they have no charge. They have a mass of 1 a. m. u. Atoms have the same number of protons and electrons. This makes them neutral.

ATOMIC STRUCTURE Quick Recap: � Atoms are the smallest part of an element with the properties of that element. � Atoms have a nucleus with protons and neutrons. This is surrounded by shells that hold electrons. So what does that look like? � Diagram of the Bohr Model of the Atom:

Atomic Structure Niels Bohr came up with the simplified model of the atom. Look at these examples of Bohr models of different atoms:

Info from the Periodic Table: (Use the Periodic Table from the pink reference sheet in the bin on your desk) Atomic number = # protons = # electrons Atomic Mass number = # protons + # neutrons

Element Mass # Atomic # # of Protons # of Electrons # of Neutrons Hydrogen 1 1 0 Helium 4 2 2 Lithium 7 3 3 3 4

Atomic Structure: Let’s practice drawing the Bohr model of these elements: R E M B E R Hydrogen Sodium Phosphorus Sulfur Boron Chlorine

Atomic Structure: Ions

Atomic Structure: Ions are atoms that have lost or gained electrons. They do this to achieve a noble gas configuration to be more stable. They have unequal numbers of positively and negatively charged particles.

Atomic Structure: Ions This causes them to have a charge attached to their symbol. This charge is referred to as the oxidation number. �If an atom loses electrons, it will have a positive charge (cation). Eg. Mg+2 is a Magnesium ion with 12 protons but 10 electrons. �If an atom gains electrons, it will have a negative charge (anion). Eg P-3 is a Phosphorus ion with 15 protons but 18 electrons.
