Most reactive metal and non-metal?
What is Francium and Fluorine
100
Charge by induction - what is it and how does it happen?
What is movement of electrons within a substance, caused by a nearby charged object, without direct contact between the two objects E.g. Holding a negatively charged balloon near a wall - repels electrons in wall, causes positive charge on surface of wall
100
Difference between food chain and food web?
What is food chains show the flow of energy in one direct pathway, while food webs are many food chains combined
100
Solar prominence vs. flare?
What is prominence - often curved stream of particles. Flare - explosion on the surface of the sun
100
Which WHMIS symbol indicates prolonged toxic effects (E.g. causes cancer)?
What is Capital T with dot at the bottom
200
What are cohesion and adhesion?
What is cohesion is how water molecules stick to other water molecules, while adhesion is how water sticks to other surfaces.
200
Does the hold on electrons get stronger as you go down the triboelectric series, or up?
What is down
200
How does the amount of biodiversity in a forest compare to a golf course?
What is less biodiversity in a golf course
200
What term describes a collection of stars?
What is galaxy
200
Covalent vs. ionic bond?
What is covalent bonds are between two non-metals, where electrons are shared. Ionic bonds are between a metal and a non-metal, where electrons move from metal TO non-metal, and they become oppositely charged.

When something flows more slowly than water, what physical property does this describe?
What is viscosity.
400
What did the gold foil experiment prove?
What is atoms have a nucleus that is positively charged.

You design a circuit to have light bulbs in series. If you were to add one more, what would happen to the brightness of the other light bulbs?
What is shine less brightly.
400
Large geographical region containing similar ecosystems?
What is biome.

What is a sunspot?
What is a region of the Sun's surface that is cooler than the rest of the sun.
400
Order for a LUNAR eclipse?
What is Sun --> Earth --> Moon

You find an atom of cobalt that has 27 protons, 32 neutrons, and 24 electrons. What is its mass, atomic number, and charge?
What is 59, 27, +3
500
What is the purpose of the finger during charging by induction?
What is allows for more electrons to flow in/ out to allow the electroscope to remain charged after interaction
500

What is the name for the layer of the sun outside the radiative zone, where hot plasma oozes up towards the surface, and as it cools, sinks back down?
What is convective zone.
