What is the difference between a heat mat and a heat plate?
Heat mat - protects bench
Heat plate - like a stove
What are the states of matter from least to most packed.
gas - liquid - solid
What is a funnel used for
to hold the filter paper during filtration
What is the largest living structure on Earth, found off the coast of Queensland?
GBR
What sport does Miss Barnett play?
Volleyball
What piece of equipment do you look through to magnify small objects like cells or crystals?
Explain, in terms of particles, why perfume can be smelled across a room a few minutes after the bottle is opened.
Diffusion — gas particles spread out and move from high to low concentration.
What method might you use to separate salt and sand from each other ?
add water, filter and then evaporation
What colour and design is on the Australian sports uniform that almost every national team wears?
Green and gold
How old is Miss Barnett?
24
Explain why you should always use a wire gauze mat when heating a beaker over a Bunsen burner flame.
It spreads the heat evenly across the base of the glassware and prevents the glass from cracking due to localised, intense heat.
What happens to the particles in ice when it melts into water?
They gain energy, move faster, and start sliding past each other instead of staying in fixed positions.
What method would be used to separate iron fillings from sand
using a magnet
What biscuit brand makes Tim Tam's?
Arnott's
What is Miss Barnett's new name going to be?
Mrs Balugo
What is the difference between using a measuring cylinder and a beaker when you need an accurate volume of liquid, and why does it matter?
A measuring cylinder gives a precise, accurate volume due to its narrow shape and fine graduations; a beaker only gives an approximate volume.
A balloon filled with air shrinks slightly when placed in a freezer, even though no air has leaked out. Using particle theory, explain why this happens.
The cold air particles lose kinetic energy and slow down. They collide with the balloon's walls less frequently and with less force, so the pressure inside drops and the balloon contracts.
What is activated charcoal used for?
Absorption - due to its large pores
What was Australia's last world cup score and who are they versing on Saturday?
2-0 and USA
What job did Miss Barnett have before she became a teacher?
A strawberry picker
Name the two parts of a Bunsen burner you adjust to control the air supply and gas flow, and what each one does.
The collar/air hole — adjusts air supply, controlling flame colour/temperature; the gas tap/valve on the gas tap at the base — controls gas flow.
What is density and the formula?
Density = mass/volume g/cm3
Measures how much mass per volume
What method would enable you to drink the dirty water.
Distillation
This venomous Australian creature found in waterways and estuaries is one of the only mammals that lays eggs and detects electrical signals from prey.
Platypus
What month is Miss Barnett getting married?
