i thought i'd make this thread as i'm hoping that it would help each and every GCSE student that is a member of this forum (and possibly even people who aren't members of this forum).
here, you can post anything that you've learnt today...bearing in min that this is a science and maths thread ONLY...i dont want to see posts regarding the climate or the nazis. this can aso be regarded as a thread where you can ask questions that you do not know the answer to or even quiz each other.
but...as quite a lot of threads, this thread requires you to sign a set of rules.
no googling the answer, copying and pasting...feel free to research the topic, make notes...and then come back to answer...that is once you know that you have learnt the topic well.
no off-topic posting (duh!)
if you are a non GCSE student willing to help us poor enslaved students, feel free to do so.
you can only post an answer to a question if you are a GCSE student...but anyone (even if you are not a GCSE student) can ask GCSE science or maths related questions.
*hmm...i think there were more rules...but i've forgotten them...so that's it for now*
this thread can also be used as an excuse as to why you are being online when you are supposed to be revising for your exams...but if the excuse doesn't work, i am not to blame...*i know, i never was a good influence on kids*
first question (as today, i didnt learn anything in school cause i wasnt bothered)...
1. What are the three different types of rocks? Examples for each of the types.
2. Two types of igneous rocks and one example for each type.
What is the group of elements with full outer shells called?

a cylinder has two circles...ie the two surfaces...and the tubical (?) surface...to find the surface area of the two circles, use the normal circle area formula ie...area= pi x radius^2
timesthe answer by two to find out the surface area of both the circles.
to find the surfac area of the cylinder body, find te circumference of the circle which is...2 x pi x radius...times the answer with the lenth to find out the surfce area of the cylinder body (aka the 'tubical' surface).
and this answer with that of the 2 circles calculated in the first part...and you should get the answer.

to understand that, you must first understand how to calculate the number of atoms in a compound.
to begin, tell me the number of oxygen mlecules and the number of hydrogen molecules in the water fomula

Ionic bonding is when two atoms bond together by losing/gaining an atom, groups in the periodic table should also be put into consideration when the Ionic bonding is concerned.
The groups are to show the outer most electrons in the final shell of an atom, for example, Na (sodium) is in group 1, and hence has 1 electron in the outer shell. Sodium has 11 electrons, in order for an atom to be stable, the electrons in the shells must satisfy this ordering: 2(first shell):8(second shell):8(third shell):18....and so on, in this case it will have 2:8:1.
So now, in order to become stable it must react with an element from group 7 to satisfy 8 electrons in the outer shell. However, because there is only 1 atom, it is easier to give away that one electron to the other element in group 7 in which the G7 element satisfies the 8 in the outer shell pattern.
Electrons are negatively charged, and protons (in the nucleus) are positively charged, and because the negatively charged electron has been lost there are 8 protons (+ charged) so the Na atom now becomes a positively charged atom.

for double science, we dont really need to know much about this topic except the example about oil and water. because they cannot be mixed together, they are immiscible. they can only be mixed for a short while when you shake them up. this type of mixture is called an emulsion. in salad cream, the egg yolk is known as the emulsifying agent. food (such as chocolate) contain E numbers which are emulsifying agents.
whilst revising this topic, i had a look at the triple science bit, and found out about colloids. a colloid is a finely dispersed mixture of two or more substances that do not dissolve into each other.
next:
Multiply out and simplify the following:
(3x - 1)(2x + 5)

Do we wink or act playfully with the opposite gender in in real life interaction? No (I hope). So behave modestly towards the opposite gender in your posts as well.
