Week 32

The first lesson was R.E; we talked very much philosophically about the existence of God, reasons for and against his existence.
Our next lesson was Science; we started by looking at study element 3 and 4.
Study element 3 is too monitor own subject knowledge for lesson 9/10, this means making concept maps for all major elements of science. It also entails furthering subject knowledge, by keeping track of reading and going back to power points.
Study element 4 is due in session 5, it is to identify health and safety in national curriculum and what it implies for teachers, this should be about a side of A4, size 12 font, double spaced. Also, to complete a risk assessment for a lesson involving collecting plants and animals near a pond, this is about 750 words.
The next part of the lesson involved a candle observation; we lit a candle and wrote our observations as it burnt.
After this we saw a water cycle demo:
• Ice goes into water on a hot plate
• Ice will melt
• Water will get hotter
• Water will boil
• Water levels will change
• Evaporation

All energy goes into melting the ice, so until all the ice has melted the temperature will stay the same.
A solid can hold its own shape and cannot be compressed.
A liquid fits the container, cannot be held easily and cannot be compressed easily.
A gas has no fixed shape, will fill the space it is in and can be compressed.
What are in between particles? Nothing.

Atom: Really small, it builds up everything.
Element: Pure forms of things. Specific number of protons and electrons make up 1 type of atom.
Molecule: Collection of atoms.
Compound: 2 or more different elements banded together.
Mixture: Two or more different substances not banded together.

A colloid suspension is a solid that does not dissolve into a liquid but instead mixes with it.

Rust is Iron oxide.

Protons = positive
Electrons = negative

Endothermic takes in energy
Exothermic gives out energy.

Chromatography is putting an ink blot on paper and dipping it in water, then watching the ink go different colours as the water goes through the paper.

Fuel + oxygen = carbon dioxide + water + heat.

Sublimation is a solid turning straight to a gas, like dry ice.
