Hot Stuff 1
Our Experiment
ASK A QUESTION
How does something get hot?
DO BACKGROUND RESEARCH
What do we know already?
CONSTRUCT A HYPOTHESIS
CARRY OUT AN EXPERIMENT
Heat seeds in water in a test-tube and
see how they move.
See what happens when we touch metal
in icy water
ANALYSE YOUR DATA
Discussion on your observations

Hot Stuff 1
Background Research
The law of Conservation of Energy
Energy cannot be created or destroyed
- it can only be transferred from one
type to another.
Hot Stuff 1
Background Research
Heat is a common form of energy
We burn coal, oil
wood (chemical
reaction)
We get it from the
sun (nuclear
reaction)
We heat wires
(electrical current)

Hot Stuff 1
Question?
But how does the heat get from
these to us? How does it flow?
Conduction – heat flow through
solids
Convection – heat flow through
liquids and gases by moving
them around
Radiation – heat flow by
emitting “light” – like we get
from the sun
