Mindbender: Essential Question: “Why does Matter, matter?” 10.03.2017
Guiding Question: “How is an atom modelled?”
Two men, starting at the same point, walk in opposite directions for 4 meters, turn left and walk another 3 meters. What is the distance between them?
Continue the following number series with the group of numbers below which best continues the series?
1 10 3 9 5 8 7 7 9 6 ? ?
Answers: sqrt(3*3 + 4*4) * 2. They make two right triangles.
Alternating numbers go up by 2, and down by 1.

What is an Atom?
at·om ˈadəm/ (n): the basic unit of a chemical element.
• The word “atom” literally means “not-cuttable”: a meaning ‘not’ and tomos meaning ‘to cut’.
• On the other end of the spectrum, the word “universe” literally meaning ‘one whole,’ was originally chosen to denote ‘everything’. The universe was/is the whole of wholes.
What is a Molecule?
mol·e·cule ˈmäləˌkyo͞ol/ (n): a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
What is Matter?
Anything that has mass (grams) and takes up space (volume)
What is Mass?
The amount of matter a substance possesses.
A quantitative (numerical) count of matter (in grams)
What is Volume?
The amount of space a substance takes up.
• Measured in cubic centimeters (cm3) for solids and
• milliliters (mL) for liquids.

What are the 3 Subatomic Particles? What are their charges? Where are they located in the atom?
Subatomic Particles:
Proton – a positive (+) electrostatic charge with a mass slightly less than a neutron. The proton is found along with neutrons in the center (nucleus) of the atom. Determines the atom’s identity (atomic number).
Neutron -- no electric charge (0) and a mass slightly larger than a proton. Protons and neutrons (each with mass ≈1 atomic mass unit) constitute the nucleus of an atom.
Electron -- a negatively charged (-) particle found orbiting outside the nucleus in various electron shells. An electron’s mass is 10,000 times smaller than that of a proton.
(Note: The outermost electron shell which determines chemical reactivity is known as the valence electron shell.)

Based on your observations, what can you infer about the identity of each substance?
What are some examples of physical properties of matter?
physical properties – Properties/characteristics that do not
change the chemical nature of matter.
Examples of Physical Properites:
http://examples.yourdictionary.com/examples-of-physical-properties.html
Boiling/Condensation Point - Temperature where a liquid forms vapor (gas) & back.
B.P./C.P. of H2O = ? °C B.P. & C.P. of Gold (Au) = 5,378°F (2,970°C)
Density - Mass per unit volume of a substance.
Density of H2O = ? g/ml Density of Gold (Au) = 19.31 g/cm3
Electrical Conductivity - A material's ability to conduct electricity.
E.C. of H2O = 1000 μs/cm E.C. of Gold (Au) = 2.44×10−8 μs/cm
Freezing/Melting Point - Temperature where a liquid solidifies & back.
F.P./M.P. of H2O = ? °C F.P./M.P of Gold (Au) = 1,948°F (1,064°C)
Thermal conductivity - Property of a material to conduct heat.
T.C. of H2O = 0.016 W·m−1·K−1 T.C. of Gold (Au) = 318 W·m−1·K−1
Volume - Space that a substance occupies.
Volume of H2O = varies Volume of Gold (Au) = varies
Mass – Amount of matter & an object's resistance to being accelerated
Ductility - Ability of a substance to be stretched into a wire.
Pliability – Flexibility. The ability to bend.
Malleability - Ability to form a thin sheet by hammering or rolling a material
Luster – Shininess. The way light interacts with the surface.
Color - Hue of an object as perceived by humans
State of Matter (phase) – solid/liquid or gas.
Magnetism - Force that the magnet exerts on the substance.

What is Physical Change?
physical change – any change NOT involving a change in the substance's chemical identity.
Examples:
• any phase change (between solid, liquid and gas) involves only the
amount of energy in the sample.
• Tearing of paper
• Breaking of glass
• Melting of ice
• Bending of a paperclip
ID CCSS Standards:
6.S.1.6.4 Use evidence to analyze data in order to develop descriptions, explanations, predictions, and models.
6.S.1.6.6 Communicate scientific procedures and explanations.
9-10.B.1.2. Develop scientific explanations based on knowledge, logic and analysis.
