What the World is Made of• Anything that takes up space is

called MATTER• It makes up everything in the

world

• Matter is made of small particles called ATOMS

Parts of Atoms• An atom is mostly empty

space surrounding a

tiny nucleus

• An atom is made up of:• protons

• neutrons

• electrons

Nucleus• The nucleus is at the center contains most of the mass of the atom.

• The nucleus contains:• Protons: Positively-charged (+1)

• Neutrons: Neutral particles, which have no charge (0)

• Mass is the amount of matter in an object• How much stuff is in it

• Which has more mass? A pillow or a dictionary?

Outside of the Nucleus

• Electrons- NEGATIVELY (-1) charged particles that move around the nucleus

• float in an electron cloud around the nucleus

** If the nucleus were the size of a period, the cloud would be 5 meters in diameter

How Big are these Particles?

Particle Charge Mass (g) Mass (amu)

Proton +1 1.67 X 10-24 1.007

Neutron 0 1.67 X 10-24 1.0087

Electron -1 9.11 X 10-28 0.00054

AMU – atomic mass unit

Can calculate the mass of an atom in AMU’s or grams (g)

Electrons are the smallest particles!

• Element: An element is a PURE SUBSTANCE made from atoms that all have the same # of PROTONS.

PROTONS

• Atoms of the same element have the same number of protons

• EX: All Aluminum atoms have 13 PROTONS

• # protons =ATOMIC NUMBER.

Atomic Number – Periodic Table• Elements on the periodic table are listed in order of ATOMIC NUMBER

Number of Neutrons in an Atom

• Atoms of the same element have the same number of protons

• BUT they can have different numbers of NEUTRONS

• Atomic Mass = #protons + #neutrons• Atomic mass is like the “weight” of the atom so you add

the neutrons and protons together•Don’t bother adding the electrons because they weigh

so little

•Atoms of the SAME element that have DIFFERENT numbers of neutrons are called ISOTOPES.

Assignment #5 Matter and AtomsLO: To describe the parts and structure of an atomEQ: What is an atom made up of? What is the structure of an atom?

LEVEL ZERO VOICE

THIS IS THE PROCESSING TASK FROM WEDNESDAY SO MAKE SURE YOU DO IT IN WEDNESDAY’S PROCESSING TASK!!!

1. Make flips for atomic number, atomic mass2. Draw an atom and label the parts of an atom.

Your processing task needs at least 3 colors!Don’t forget your “I can” statement.

Scientific Skills• Scientists use skills such as observing,

predicting, classifying, and making models to learn more about the world and make scientific progress

• Observing - Using one or more of your 5senses to gather information.

2 Kinds of Observations

1. Quantitative Observation• quantity = amount

• you can count or measure

2 Kinds of Observations

1. Quantitative Observation

Example: You observe 8 new emails in your inbox.

2. Qualitative Observation• describe the quality of something (round,

blue, warm)

• that cannot be expressed in numbers

2. Qualitative Observation

Example: You observe that a bicycle is blue or that a grape tastes sour.

• Inferring - To make an informed guess based on what you observe.

• NOT wild guessing.

• based on reasoning from what you already know.

Inferring

Example:

Your friend does not arrive at school with her regular carpool in the morning, so you can’t hang out together before school. You see her later in the day and she looks very tired.

What can you infer from this situation?

Inferring

Example:

Your friend does not arrive at school with her regular carpool in the morning, so you can’t hang out together before school. You see her later in the day and she looks very tired.

What can you infer from this situation?

Answer: she probably didn’t sleep well.

Why we make models.

• Making models: Creating a representation of complex objects or processes.• Example: globe, DNA model

• Models help people study and understand things that cannot be seen directly.

Example:

A globe is a model of the Earth that shows where continents, oceans and countries are. You can’t see these directly unless you are an astronaut.

Write 2 examples of your own.

Scale Model

• Scale model: Shows the correct proportions between the parts.

• It can be larger or smaller than the real thing.

Write this as a thought bubble next to your notes

• Give an example of a scale model that is smaller than the real thing…

• Give an example of a scale model that is larger than the real thing.

• Classifying - The process of groupingtogether items that are alike in some way.

• Example:

• In the grocery store you can find milk in the dairy section, carrots in the produce section and bread in the bakery section.

Assignment #6 Inferring vs. ObservationsLO: To describe the difference between observations and inferences.EQ: Compare and contrast: qualitative observation, quantitative observation, inference.

LEVEL ZERO VOICEPROCESSING TASK (10 minutes, individual work):

1. Write definitions for:• Qualitative observation• Quantitative observation• Inference

2. Next to the definitions draw pictures of each definition.3. I want you to write the keywords in colored marker. The definitions can be in pencil.
