Activity Warm Up: copy this data table onto page 11 Session # Page # 6 Date Session # Activity Page # 9/14-15 6 Matter 12 States of Matter Notes 13 Parts of an Atom….using skills from kindergarten 14 Atomic Structure Text Talk 15 Atomic Structure Notes 16 Homework: Study for Element/Compound/Mixture Test Monday 9/18 Review Sessions: Thursday 9/14 8am and after school

Separating Mixtures What processes are used? Compounds Elements Homogeneous (solutions) Heterogeneous Evaporation LG Distillation – uses the different boiling points of components to separate a solution (evaporation followed by condensation) Sifting Filtering Separate using chemical reactions components are chemically combined Cannot be broken down into simpler substances.

TLW explain how the arrangement of matter is reflected in the three states of matter by: summarizing notes and classroom demonstrations, comparing and contrasting subatomic particles, explaining a cartoon using scientific vocabulary and summarizing statement.

8.P.1 Understand the properties of matter and changes that occur when matter interacts in an open and closed container. 8.P.1.1 Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements.

Gas mass demonstration Page 12 What’s The Matter Matter – anything that has mass & volume IN OTHER WORDS… EVERYTHING IS MATTER! There are 3 States of Matter common on Earth: Solid, Liquid & Gas Gas mass demonstration

Solid.. Particles vibrate in place Solids have a definite volume and definite shape Regardless of the container, a solid will keep it’s shape and its volume will not change. Example: density cubes..

Liquid… In a liquid, particles slide past each other Liquids take the shape of their container and have a definite volume. Example: water in containers For example: a sample of liquid water can have a columnar shape, flat shape, etc.. The volume stays the same.

Gas….. In a gas, particles move freely with high speed energy. Gases have no definite volume and no definite shape. Example: balloon Hallway activity Gases will occupy the maximum amount of space available.

Moving from one phase to another... To move between solid, liquid or gas phases a particles must gain or lose energy. This is a physical change, no chemical bonds are broken, no new substances created. Label energy changes Label process involved in the change

Moving from one phase to another... To move between solid, liquid or gas phases a particles must gain or lose energy. This is a physical change, no chemical bonds are broken. Increasing energy Increasing energy Decreasing energy Decreasing energy

Identify phase/state, process and energy for each arrow. Top 1/3 of page 13 1 2 3 Tape this diagram to the top of p. 13 Identify each phase as: solid, liquid or gas Copy the arrows that are on the board Label the arrow as increasing energy or decreasing energy Place the following processes on the correct arrow: melting, cooling, evaporation condensation, heating, freezing, boiling

Parts of an atom…. using skills from kindergarten! Proton P + Neutron N 0 Electron e - each part needs its own color scented marker

What is the structure of matter? Talk to the Text Annotate this text – write on it These are three different texts that represent atomic structure. Read with the questioning stance: “What Surprised Me?” Read it again: What questions do you have? What connections can you make to the previous unit or experiences? p. 15 How are protons represented? How are neutrons represented? How are electrons represented? How have we heard electrons described in the previous unit? -- push for valence..where are they in this diagram? What do p & n have in common What other words sound like electron? electricity they have the same root word, how are they related?

Elements are substances that are made up of only one type of atom Atoms make up elements So what’s an element? Elements are substances that are made up of only one type of atom (There are about 100 different elements & each element is made of a different atom)

So what’s an atom? Atoms All matter is made up of atoms An atom is the smallest particle of matter P 16 Atoms

Atomic Structure Atoms are made of even smaller parts called subatomic particles. They are found in the nucleus and electron cloud of an atom. So where are the subatomic particles?? Nucleus – the center of an atom Contains all the mass of an atom Does not take up much space in the atom

? Electron Cloud: all of the electrons circling together around the nucleus Occupies most of the space in an atom. Atomic Structure

BOTH are found inside of the nucleus Protons & Neutrons (Protons & Neutron are about the same size and mass) Protons Neutrons Protons have a positive (+) charge Neutrons have no (0) charge BOTH are found inside of the nucleus

Electrons: Electrons have a negative (-) charge Electrons are MUCH smaller than protons or neutrons Electrons orbit the nucleus on paths called energy levels (or shells)

Bringing it all together… For example, OXYGEN is an element on the periodic table. It is made of only one type of atom Actual Oxygen Atom Oxygen on the Periodic Table

In the rest of p. 13… Compare and contrast protons, neutrons and electrons.

You will see this again, as a quiz Explain the following cartoon. Your answer should be in complete sentences and use correct vocabulary. Vocabulary today: Matter States of Matter Solid Liquid Gas Atom Element Proton Neutron Electron Volume Mass

One more time. Read and reflect on the question. Answer the question One more time. Read and reflect on the question. Answer the question. Make sure your response is full of as much vocabulary as possible. Use complete sentences. How are matter, elements and atoms related? Vocab we have used today: atom, proton, neutron, electron, element, matter, solid, liquid, gas
