Here's a very simplified answer, and something most 5th graders have learned.

We live on a planet.
This planet is called Earth.
The Earth rotates around the sun. (this has been proven, btw)
The Earth also spins on an axis.
This axis is not vertical, but tilted.
This tilt means that at any time during the year, either the northern or the southern hemisphere will be the recipient of more of the sun's energy.
When the energy is most direct on a certain hemisphere, that part of the earth will experience summer.
In Australia, this falls in line with a month on our calendar that is called January.

I hope this helps.
