Sources of Heat
It was the last day of the fireworks festival in Vancouver and Minime desperately wanted to attend. On days like this it is very easy to inspire him to do his best with his studies ... when there is a clear reward at the end of the day to carrot and stick with.
We have been working through the Canadian Curriculum Workbook and reviewing what he learned in Grade Seven Physics. Yesterday it was the sources of heat. What follows stems from our studies and is a joint effort.
Heat makes us feel warm. It comes from the release of energy. There are six major sources of heat.
- Chemical energy comes from the burning of 'fuels' or through processes like digestion, where macro-nutrients are broken down to micro-nutrients that can be used as fuel for the cell.
Nuclear energy (outside of stars, fusion) results in the splitting of the atom, fission. It results in heat and energy release but also radioactive particles and waste.
Mechanical force comes the push and pull of objects. This push and pull creates friction and faster moving particles.
Solar energy is the radiant energy that comes from the sun and the nuclear reaction of fusion; the joining of atoms. Solar energy travels on electro-magnetic waves from the sun to the Earth.
- Geothermal energy comes from the intense heat and pressure found within the earth itself.
- Electrical energy come from the movement of electrons and produces heat and electricity.
The most amazing thing about academic study is when it lines up with our daily experience. I treated Minime to a day at the Vancouver Space Center and a viewing of From the Earth to the Universe. It was a huge mommy win when the narrator began to explain the heat and radiation of the sun.
