Skip to 0 minutes and 7 seconds We’re going to create our own series circuits now, okay, in the lab thinking about what we learnt to help us do that. So, on the screen you can see a circuit. We’re going to have a go now at creating this circuit and it’s going to work like this. I’m going to show you what to do, I’m going to show you each step and how to do it and then you’re going to copy me exactly and do it in your group, okay? You’ll notice that on each of your tables there is a red tray and that has all the equipment that you need in it. So you’re going to work collaboratively with each other to produce these circuits.
Skip to 0 minutes and 47 seconds This is our first one so just looking up at that circuit what are we going to need for this circuit? What components can we see? Emily? We can see one cell, exactly. A cell. What else are we going to need? Yes, we can see a buzzer there, can’t we? That’s next to the cell so we know this circuit is going to make noise and what’s that final component that joins all those other components together to make a complete circuit? The wire, exactly. We’ve got one, two wires there to create our circuit.
Skip to 1 minute and 19 seconds So you can see on the visualiser, you can see that’s my hand so I’m going to show you exactly what you need to do in the way that you need to do it. So the first thing to do is that you’re going to get your red tray and you’re going to put it in front of you and carefully you’re going to lay out all of the things from it in front of you and you’re going to do it in the middle of your table so everyone in your group can see exactly what we’ve got, okay? Do that now… Okay five, four, three, two and one. You’ve laid out your components so you can see them all now in your group.
Skip to 1 minute and 53 seconds So the first thing I’m going to do is have a little look at them. So on the screen, you’ll see I’ve put on there, that’s our buzzer. Okay so we know the symbol for a buzzer. That’s an actual buzzer and a buzzer makes noise so we’re going to need one of those in our circuit. We’re also going to need a cell and a cell looks like that there, you can see there are two batteries in there to provide electrical power. I’m also going to need two wires to join, there’s one, to join it all together. Now, if you look on the screen you’ll see the top of this cell has got these two little things there okay? Here and here.
Skip to 2 minutes and 38 seconds Now it’s quite hard to attach the wires straight to it so what you’ve also got is this thing here okay? And this thing connects to the top; it’s a battery connecter, and you connect it, you clip it onto the top of your battery and it gives you two wires which you can easily use then in your circuit. So the first thing that you need to do is this. You’re going to take your cell and you’re going to take your battery connector and you’re going to clip it on the top okay?
Skip to 3 minutes and 5 seconds Now look carefully here, you can see there’s a wide part; the wide one goes on the thinner one and you’ll feel it clip on like that and the thin one clips into the wide one okay? When you do it, you need to make sure that these two ends do not touch so make sure they’re nice and separate. Once you’ve clicked your battery connector on you’re going to leave it on your desk like that so we can move on to the next step. Off you go… Okay five, four, three, two, and one.
Skip to 3 minutes and 34 seconds So you’ll see on the screen that I’ve got my battery and my battery clip connected just like yours and I’ve got a red wire and a black wire and on the end, I don’t know if you can see? There’s a tiny bit of wire showing and that’s what we’re going to be using to connect our circuit. So the next thing you’re going to do is you’re going to take one wire. On the end of your wires you’ve got these little clips that are like little pegs that you might hang your washing out with. They’re called crocodile clips because if you look, they look like little crocodiles with little teeth.
Skip to 4 minutes and 3 seconds So we’re going to take our crocodile clip one end and we’re going to clip it very gently to the metal part of the wire. It must go on the metal part of the wire and not the plastic part because the electricity will not flow through plastic so be very careful to clip it on to the metal part only. So again you’ll have one end free and be careful that end doesn’t touch the other end just yet. Off you go.
Modelling learning using a visualiser
In this video, Lewis Angier, Teacher at Fulbridge Academy (primary), demonstrates how he makes use of a visualiser during lessons to support his presentation, explanation and modelling of new learning.
If you’ve chosen to watch this case study, consider what it reveals about the importance of purposeful use of education technologies. Click next at the bottom of the page to skip to the next case study if you’ve chosen to focus on a different one this week.
A visualiser can be attached to a computer and projector in the classroom to display a close-up view of something such as a piece of work or a demonstration. Lewis uses the visualiser in this case study to demonstrate the steps of a science experiment to his pupils. He explains the steps one at a time and uses the visualiser to provide clear instructions before releasing the pupils to engage with each step at a time so as not to overload their working memory. You’ll learn more about these approaches in Week 2 of the course.
