- How did you make this a
make it a fair test all the spoons
were put in the hot water at the same
time. Another thing to make
it a fair test is to try and use the

- Can you decide which spoons
are good conductors and which ones
are good insulators?
is something that lets energy flow
is when heat energy travels through
a solid material is heated the particles
in it gain energy and vibrate more.
energy is passed on by the particles
bumping into each other.
are very close together in solid materials
and therefore solids make good conductors.
not good conductors and gases hardly
conduct at all.
