what is this?
draw a diagram to show how it was made
what can you see in this photo

in a coal fired power station electricity is created by the?
which of these is a form of energy
heat
sound
kinetic
all of the above
the process whereby solar energy is created is called
nuclear power is created by splitting this atom
this company is responsible for most of South Africa's production of electricity
define energy
name 3 renewable resources
explain how global warming can affect our lives in the future
explain how energy is produced in a coal-fired power station
advantages and disadvantages of
solar panels
coal
hydro
wind
how would you make South Africa more energyand environmentally friendly
renewable energy resources
hydroelectric
solar panels
photovoltaic cells
the suns energy can be used from solar panels when there isn't any sun in what way?
explain why a solar water heater can save electricity
why is it better to use energy saving light bulbs
The planets in order based on their distance to the sun (near to far)
Inner Planets
Outer Planets
Difference between rotation and revolution
What makes a planet a planet
Characteristics of Inner and Outer Planets
mercury
venus
earth
mars
jupiter
saturn
uranus
neptune
planets and asteroids take different amounts of time to revolve around the sun
our solar system
moons
moons surface
moons
give three ways in which gas giants differ from other planets
rotation
earth spins on its own axis
rotation of the earth causes night and day
plsnets revolve around the sun in their own orbits
the earth revolves around the sun in its own orbit in 365 and a quarter days = a year
rotation of the moon
revolution of the moon
the movement of a body in space around another body is called
the movement of an object in space around its own axis is called
the path in which an object moves round another is called its
the time for the earth to revolve around the sun is called a
the time taken for the moon to revolve around the earth is called a
the imaginary line through the centre of the earth is called its
telescope
lens
telescope invented by
optical telescopes=
radio telescopes =
radio telescopes can only collect a small amount of information so we need a group of telescopes called
array
earth's atmos[here stops us getting perfect images from space so send telescopes to space that work as satelites
most famous space satellite is
telescopes in South Africa
have best conditions for observing space = plenty of good weather, clear skies, places away from lights if buildings and pollution
Rovers on the moon and Mars
how a telescope works
exploring the moon
timeline - history of rovers in space
timeline - history of rovers in space
rovers
NASA
when did the first person land safely on the moon
when did the first rover land on the moon
which three missions used Lunar Roving Vehicles driven by astronauts to explore the moons surface
What makes it difficult to send people to mars
is it important for people to gather information about the moon and mars? give reasons
prototype
