What are the three subatomic particles in an atom (and their charges)
Proton (+), Neutron (neutral), Electron (-)
100
What is the unit of measurement for current
A- Ampere ("Amps")
100
What is the difference between biotic and abiotic factors
Biotic: living, or derived from a living thing (examples/ bear, fish, bacteria maple tree, dead leaves)
Abiotic: Non- living (examples/ water, temperature, sunlight, precipitation level)
100
What Particle is gained or last in the formation of an ion
an electron
100
What is the name of the element with the symbol "Na"
Sodium
200
What is the atomic number of Boron
5

In a series circuit with 3 light bulbs, what happens if one bulb goes out?
In a series circuit, if one bulb goes out, all the other bulbs in that circuit will also go out. This is because the circuit is a single loop.
200
What is Biodiversity?
The variety of life on earth. This includes variety withing species (aka genetic biodiversity), and variety within and between ecosystems.
200
What is one thing that can increase resistance in a circuit?
Thin or Long Wire
200
What information does an element's atomic number tell you
The number of protons and electrons in the atom
300
Chat happens to an atom in order for it to become a cation (+)
Cations are positive; caused by the loss of (an) electron(s)
300
In a parallel circuit, what happens if one bulb goes out?
In a parallel circuit, if one light bulb goes out, the other bulbs will remain lit and continue to operate normally. This is because each bulb in a parallel circuit has its own separate path.
300
Rank the following from least to most concern:
Extinct in the wild, vulnerable, critically endangered, extinct, least concern, endangered
Least Concern --> Vulnerable --> Endangered --> Critically Endangered --> extinct in the wild--> extinct

Name 3 of Canada's Biomes
Terrestrial: Tundra, Boreal Forest, Deciduous Forest, Temperate Coniferous Forest, Grasslands
Aquatic: Freshwater, Marine
300
Name an adaptation that helps an animal to survive in the tundra
The Tundra is cold, and covered in a layer of permafrost. Therefore adaptations like a blubber layer, thick fur, white fut, or seasonally changing fur coloring (white in winder, grey/beige in summer).
400
What is the difference between a chemical and a physical change?
In a physical change, no new substance is formed (example/ change of state). A chemical change is always accompanied by one or more new substance(s) (example/ magnesium is burn in oxygen to form magnesium oxide).
400
What is the voltage if a resistance of 25 Ω produces a current of
250 amperes?
V = I x R
V = (250) (25)
V=6250 Volts
400
Identify the producers in this food web
Star Cactus, Grass, Cactus
400
What is the current produced by a 9-V battery flowing through a resistance of 200 Ω?
I=V÷ R
I = (9) ÷ (200)
I = 0.05 Amps
400
Which type of circuit is used in homes (series vs parallel)
parallel

Draw the Bohr Rutherford diagrams for a Magnesium atom and a Magnesium Ion
(Loss of 2 electrons from the valence shell, resulting in a charge of +2

Name two renewable and one non-renewable energy source.
Renewable: Hydro, Tidal, Geothermal, Solar, Wind,
Non- Renewable: Coal, Natural Gas, Fossil Fuels

Identify a secondary consumer from this food web
Here are a few examples
Lizard (example grass--> grass hopper--> lizard),
Tarantula (star cactus--> Kangaroo Rat--> Tarantula),
Rattle Snake (star cactus--> Kangaroo Rat-->rattle snake),
Hawk (Grass--> Rabbit--> Hawk)
