OK, guys, bring your chairs around the front, please.
Now, if we go on a journey...
0, we don't understand it.
10, we fully understand it.
Let's get some full understanding as to how that process works,
how an image was formed.
Any ideas, folks?
Let's take little steps towards trying to find out the correct answers
to why we were able to see an image on that piece of paper.
Any ideas, guys?
Yes. Grainne.
Something to do with reflection?
Reflection is involved.
You've taken us a little bit along the way there.
OK, you've taken a big step towards full completion.
During the lesson I did that idea that they're on a journey of discovery.
10 is the perfect answer
and everyone can contribute to us reaching that final destination.
And so the weakest student to the most able student
is able to contribute to that.
Again it's just a skill you pick up with more and more experience.
You know which kids are going to lead you to a certain destination
and you give everyone an opportunity, basically.
Is it something to do with how light travels?
It is to do with how light travels. Light travels in a very special way.
That's one of the things I want you to get today, what they have in common.
You've taken us about that far there.
It's to do with reflection and the way light travels.
- Emily. - Does it mean when...
If light travels in straight lines,
because you put something in the way it bends it, so it flips it.
Oh, that's so good.
It is light travelling in straight lines.
That's the point I'm trying to drive at here.
This is proving that light travels in straight lines, and we'll see how.
How are you able to see me? How are you able to see me?
What's the process by which you can see me?
- My eyes. - Your eyes. Good.
Is something coming from your eyes to me
or is something coming from me to your eyes?
- What do you think? - Light.
Light. Is it coming from me to you or is it going from you to me?
Is it a case of... There's your eyes and I'm here.
Is the light going that way, A,
or is it going that way, B?
Chat amongst yourselves, 30 seconds. Which way is the light going?
A to B.
Obviously it's a high level of skill
for kids who lack a little bit of confidence
to speak more cohesively to the whole year group and the whole class,
and I find that by doing small group-work discussions
and them gaining the confidence then to articulate themselves,
they will on occasions enter the larger discussions
if I've checked with them before to say, "You've got the right answer."
"I think you need to share that with the class."
And it's a virtuous circle.
OK, when you see me, who thinks the light's going from me to her?
Who thinks that?
Who thinks it's going the other way?
OK. Well done for having a go.
Unfortunately you're not right.
The light is definitely going...
Because if it was going from you,
theoretically I could open up a door where it was dark
and you'd be able to see inside a dark room.
You'd be lighting it up.
The light is definitely coming from me,
it's hitting me and going into your eyes.
