Grade 7 Science Notes for October 25th

Viruses

- Viruses: Non-living particles cuasing disease
- No nuclues, cell membrane and other organells.

Q: since there is no nuclues, how do viruese multiply? (you need a nuclues in order for cells to multiply)
A: they need host cells (See Figure 15, on Page, 55)

Active Viruses: "Killing viruses".
They multiply causing host cells to die

Latent Viruses: "Sleeping Viruses"
They wait, then many years after, at certain conditions, they become active.

How do viruses affect organisms
1. Viruses attack animals, fungi, protists, and all prokaryotes
2 "lock and key": most of viruses only attack one specific type of cell because the viruse and the place where it attaches must fit together

Science Test: October 20th, Tuesday
Homework : Page 62. Questions 1-18. Due: Monday!

Grade 10 and 11 Extra Concentration Questions (& solutions)

1. Brine is a solution of sodium chloride (NaCl) at 18% m/V, which is used to preserve certain foods. To prepare 250 mL of brine, how much salt must be dissolved?

Problem-solving steps	Application
1. Determine what you are looking for.	The mass of salt needed to prepare 250 mL of brine at 18% m/V
2. Determine the different variables and their respective values.	C = 18% m/V V = 250 mL m = ? g
3 C = . Choose the appropriate formula.	m V
4 = . Replace each variable by its value and isolate the unknown variable.	18 g ? g 100 mL 250 mL Therefore m = 45 g
5. Check your solution and answer the problem question.	The amount of salt needed to prepare 250 mL of brine at 18% m/V is 45 g.

CHAPTER 6 SUMMARY (Homework: WORKBOOK PAGE 95-100)

1 THE LITHOSPHERE

 

• The lithosphere is the hard shell of the Earth, consisting of the crust and the topmost part of the upper mantle (p. 184).

• Minerals are solid inorganic substances with clearly defined composition and properties (p. 185).

• Geologists classify minerals according to their properties (p. 185).

• To mine minerals, geologists must first locate them and then extract them from the lithosphere (p. 187).

• Ore is rock containing minerals. When the amount and concentration of a mineral in a particular site are high enough for mining, the mineral layer is then referred to as a deposit (p. 187).

• Once the ore has been extracted, the mineral is separated from the rock in several stages (p. 189).

• Rocks are heterogeneous solids composed of many minerals (p. 189).

• Igneous rocks are formed when magma cools and solidifies (p. 190).

• Sedimentary rocks are formed by the accumulation and compaction of debris (p. 191).

• Metamorphic rocks are former igneous or sedimentary rocks that have been transformed by heat or pressure (p. 191).

• Like minerals, certain rocks are extracted from the ground to meet human needs (p. 191).

• Soil horizons are differentiated layers running roughly parallel to the surface of the ground (p. 192).

• Permafrost is ground whose temperature has been 0°C or lower for at least two years (p. 194).

• Fossil fuels result from the transformation of organic residue. These energy sources consist of oil, natural gas and coal (p. 196).

• Nuclear energy is the energy stored in the bonds between the particles in the nucleus of an atom (p. 198).

• Geothermal energy is the energy that comes from the internal heat of the Earth (p. 198).

2 THE HYDROSPHERE

• The hydrosphere is the Earth’s outer layer of water, uniting water in all its states: liquid, solid and gas (p. 201).

• Inland waters are all the freshwater bodies found on continents, uniting rivers, lakes and groundwater (p. 201).

• A watershed is an area of land in which all inland waters drain into the same larger body of water (p. 202).

• Salinity is a measure of the amount of salt dissolved in a liquid (p. 204).

• An ocean current is the movement of seawater in a certain direction (p. 205).

• Ocean circulation is the combined effect of all the currents that move across the oceans (p. 205).

• Thermohaline circulation is a huge “conveyor belt” of surface and subsurface currents that moves water all around the world (p. 206).

• The cryosphere consists of all the frozen water on the Earth’s surface (p. 207).

• Pack ice is composed of the ice floating on the oceans near the North and South poles (p. 207).

• A glacier is a mass of ice on land, formed by compressed snow (p. 208).

• Hydraulic energy is the energy that can be derived from moving water (p. 209).

• A hydroelectric dam converts a river’s hydraulic energy into electrical power (p. 210).

Grade 10 and 11 Science Chapter 1 review

A toms and elements

1 what is an atom?

• An atom is the smallest particle of matter. It cannot be divided chemically (p. 7).

• Because atoms are too small to be examined directly, scientists have devised various models to represent them (p. 7).

• According to Dalton, the atom is like a billiard ball—solid and indivisible. All the atoms of a single element are identical (same mass, same size, same chemical properties), but different from those of other elements (p. 8).

• The electron is one of the particles that make up an atom. It is negatively charged (p. 11).

• The proton is one of the particles that make up an atom. It is found in the nucleus and carries a positive charge (p. 13).

• The Rutherford-Bohr atomic model is a representation of the atom as a very small nucleus made up of positively charged protons, surrounded by negatively charged electrons moving in defined orbits (p. 15).

2 THE PERIODIC CLASSIFICATION OF THE ELEMENTS

• A periodic classification is a way to group the elements according to certain properties (p. 17).

• The periodic table of the elements is a visual presentation of the elements in groups according to their physical and chemical properties (p. 17).

• The elements can be classified into three categories: metals, nonmetals and metalloids (p. 20).

• A valence electron is an electron in the outermost shell of an atom (p. 21).

• A group corresponds to a column of the periodic table. The elements in a particular group have similar chemical properties because they all have the same number of valence electrons (p. 21).

• A period corresponds to a row of the periodic table. All the elements in a period have the same number of electron shells (p. 23).

3 REPRESENTING ATOMS

• The information needed to represent an atom is provided in the periodic table (p. 27).

• Lewis notation is a simplified representation of the atom, in which only the valence electrons are illustrated. They are placed one by one around the symbol, like the four points on a compass. When these four positions are filled, the electrons are then doubled to form pairs (p. 27).

• In the Rutherford-Bohr model, a small, positively charged nucleus is represented by a small ball containing the atomic number of the element and a “+” sign (symbolizing the protons). The ball is surrounded by as many circles as there are electron shells in the atom (the number of shells equals the period number). The valence electrons (smaller balls containing a “–” sign) are placed on the outermost electron shell in a pattern similar to Lewis notation (like the four points on a compass). The remaining electrons needed to reach the atomic number are added to complete the inner electron shells (pp. 27–28).

• As its name suggests, in the “ball-and-stick” model, the atom is depicted as a ball whose size is generally proportional to the number of electron shells. The bonds connecting it to other atoms are represented by sticks (p. 29).
