Welcome to Mrs. Guzman's 7th Grade Science Class!
- Photosynthesis – how plants create their own food using sunlight
-
- Cellular Respiration – how plants and animals break down food for energy(ATP), using oxygen.
-
- Anaerobic Respiration – respiration that occurs WITHOUT oxygen
-
- Aerobic Respiration – respiration that occurs WITH oxygen
-
- Autotroph – organism that makes its own food in chloroplasts using sunlight.
-
- Heterotroph – organism that hunts food and gets energy through mitochondria.
-
- Chloroplast - organelle where photosynthesis occurs in plant cells.
-
- Mitochondria – organelle where cellular respiration occurs in plant and animal cells.

2 - Law of Conservation of Mass Doodle Notes---POWERPOINT.pptx
- Reactant – The atoms that react(ingredients)...to the left
-
- Product – The atoms that are produced(the cake)...to the right
- Coefficient – The whole # multiplier(big number)
-
- Subscript - How many atoms you have(tiny number)
- Mass – amount of matter in a given space
-
- Chemical Equation - symbolic representations of chemical reactions in which the reactants and the products are expressed
-
- Chemical Reaction - a process that involves rearrangement of the atoms of a substance, as opposed to a change in physical form
-
- Law of Conservation of Mass(LOCOM) – matter cannot be created or destroyed
- Temperature – measure of hotness or coldness
-
- Pressure – physical force exerted on an object
-
- Intermolecular Attraction – determines the physical properties of a substance
-
- Thermal Energy – energy contained in a system that determines temperature
-
- Triple Point Diagram – diagram that shows the three states of matter for a substance
-
- Kinetic Energy – the energy of particles in motion
-
- Open System – can exchange matter and energy with its surroundings..."open"
- Closed System – cannot exchange matter and energy with its surroundings..."sealed"
- Chemical property-a characteristic of a particular substance that can be observed in a chemical reaction
-
- Physical property-any property that is measurable, or observable in a substance
-
- Melting Point – temperature at which a substance changes from solid to liquid
-
- Boiling Point – temperature at which a substance changes from liquid to gas (vapor)
-
- Solubility-the ability to be dissolved, especially in water
-
- Color-pigment visible on the outside of an object
-
- Density-the degree of compactness of a substance
-
- Flammability-ability to be set on fire
-
- Conductivity-the degree to which a specified material conducts electricity
1.Matter-any substance that has mass and takes up space
2.Pure Substance-has constant composition and properties throughout
3.Mixture-2 or more substances physically combined
4.Homogeneous Mixture- mixture that appears to be all one substance throughout
5.Heterogeneous Mixture-mixture where you can see the different substances
6.Chemical Property-characteristics of a substance during a chemical reaction
7.Physical Property-characteristic of matter that can be observed and measured without changing the chemical identity of the sample.
8.Filtration-separating materials by physical means
1.Element – pure substance made up of only one type of atom
2.Molecule – group of atoms chemically bonded together
3.Monatomic – made of only one atom and no bonding
4.Diatomic – made up of two atoms bonded
5.Elemental Molecule – two or more of the same atoms chemically bonded together
6.Compound Molecule – two or more different types of atoms chemically bonded together
7.Ionic Bond – bond where electrons are transferred
8.Covalent Bond – bond where electrons are shared
1.Atom – makes up all matter
2.Electron – subatomic particle with a negative(-) charge
3.Proton – subatomic particle with a positive(+) charge
4.Neutron – subatomic particle with NO charge
5.Nucleus – made up of protons and neutrons
6.Orbital Shell – rings around the nucleus that hold electrons
7.Valence Electron – electrons in the outermost shell
8.Atomic Number – number electrons/protons in the element
