Curiosity
Why are the numbers of cane toads in Australia so high and increasing?
No predators and poisonous

makes a paint able to be applied to a surface before it dries

different types of climate found in Australia
desert, tropical, subtropical, arid
What important step to figuring out if there was life on mars have we discovered
There was water
The term for using an animal to control another animal
What is biological control?

What cane toads were meant to eat when introduced
What is cane beetle?
Microscopic organisms discovered with microscopes around the years 1674
protozoa, bacteria, yeast, sperm, red blood cells
common binders in Aboriginal paint mixtures
saliva, honey, animal fat, tree resin and even blood
industry that is most affected by seasonal changes
Agriculture
We can see plenty of these kinds of rocks on Mars
sedimentary rocks there, like sandstone and mudstone
Three problems that rabbits cause
eating cows grass or crops, eating local plants, causing erosion by digging holes.
refraction
A deep blue pigment made from lapis lazuli rock
Ultramarine
A greenhouse is a building made of glass that
traps heat from the sun, and provides protection from bad weather
All the volcanoes on Mars are now
extinct ("dead")
When a species is invasive it causes problems for
native wildife or people
600 x
an important pigment for many Indigenous Australian cultures made from clay rock
Ochre
why different parts of Australia recognise different seasons
Because it's so big
Where or when the Curiosity landed on Mars
Gale Crater in 20122012
A description for a native species
how our understanding of living things changed with the use of microscopes
cell theory, discover of living things that cannot be seen with the naked eye, microorganisms
a black, crumbly substance which is made up of carbon
Charcoal
In Ancient Egypt, there were three seasons, based around the
flooding of the Nile
What the rover on Mars is studying
Geology (rocks)
Why cane toads increase the population of crocodiles
Goanna eats crocodile eggs, Goanna dying from eating cane toads
Using a light microscope at the highest magnification, we can magnify objects up to
1500 x
Orange paints could also be created by mixing
yellow and red
The length of daylight and night-time at the poles during summer or winter
constant daylight during summer and constant darkness/night-time during winter
A primary goal of the rover on the Red Planet
To find out if Mars could have supported life in the past (or check for water)
An Australian marsupial that may go extinct because of rabbits
northern hairy-nosed wombat
The person that discovered cork cells working with microscopes
Robert Hook
where Indigenous Australians get red pigments from
Ochre
Reasons why the seasons influence tourism/travelling
Want snow on ski-slopes, warmth and sun at the beach, and safe travelling conditions
A volcano that is no longer active is
Extinct (dead)
What types of animals are dying because of rabbits and why
frogs, insects, birds, lizards, slugs/snails, because rabbits eat all their food
The glass used to make a magnified image and the glass you look through in a microscope
Objective lense and ocular lens
where Indigenous Australians get black pigments from
charcoal
Two ways to reduce the impact of irregular wet seasons
Recycle waste water & improve water storage techniques (dams, tanks, etc)
Some rocks on Mars were formed long ago by volcanic activity, these are
Igneous rocks
The name of a virus introduced to control rabbits
Myxoma virus
A microscope that doesn't use light and can see even smaller objects
Electron microscope
the traditional colours of Indigenous Australian art
Red, orange, yellow, white and black
How many seasons there are
It depends on where you are on Earth.
Most of the rocks on Mars were formed very slowly as sand and mud piled up and were compacted into
Sedimentary rock, sandstone and mudstone
