Hi, my name's Mr. Brown, welcome to this lesson.
We're going to be thinking today about data logger cases, how to make a data logger case, all the different parts and components and materials that we're going to have to use.
So without further ado, let's get on and have a look at the learning outcomes and the learning cycles and keywords and vocabulary for today.
Today's learning outcome is to make a data logger case to securely hold a micro:bit and electrical components.
So we're going to be making something that can contain the micro:bit and all of the different components that it will need to have.
The keywords, only two keywords today.
So the keyword, first one is case, that's the covering of a product.
Sometimes it could be called a shell, but for today we're going to be calling it a case.
And the second one is components.
Components are different parts of a product.
The two learning cycles today.
First learning cycle will be preparing materials for a data logger case, and the second will be how to make a data logger case.
And of course we'll get started and we'll have learning cycle one, which is preparing materials for a data logger case.
Right, so we're going to prepare our materials for a data logger case in this learning cycle.
The first thing we need to think about is that data loggers and microcontrollers, they have cases to protect them when they're being used.
Now this can also allow the user to interact with them and access the data logger easily, so we've got to have something that actually protects the components inside but also allows the user to interact with them really easily.
Now these can come in all shapes and sizes and different colours.
Here we've got different materials.
One's made of plastic, one's made of bamboo.
And you can see there in the different examples that we've got there that there are holes and openings for the microcontrollers to fit in.
Now each design that we have has a different design specification, so of course we've got to think about what the design specification is so that we can design a product that's going to work well.
So here is the Year Four class design specification for a data logger.
If we have a look, there's six different sections here.
So we've got function, user, performance, aesthetics, materials, and environmental considerations.
So let's go through them one by one.
So the function, first of all, the designer needs to think how it will log the data, so how will the user be able to actually use it? The second thing is, how's it going to hold everything? The performance might be how the buttons will be used.
The aesthetics, so what's it going to look like? And the materials, what's it gonna be made of? And lastly, the environmental impact, so how can we reduce, reuse, and recycle materials that we use? Check for understanding.
What is the function in the data logger design specification? Is it how to reduce, reuse, and recycle materials? Is it B, what it'll be made of? Or C, how will it connect to a computer? Down to you now, for you to decide, what do you think the correct answer is? Is it A, B, or C? That's right, it's C, how is it going to connect to a computer? When we're talking about reducing, reusing and recycling materials, we're talking about the environmental impact.
When we're talking about what it'll be made of, we're talking about the different materials.
Okay, so one class member has actually created this design to meet the design specification, so Jun has actually created this idea.
And his data logger case, it's gonna look a bit like a chocolate bar 'cause that's the design that he wants to actually do.
Now, Year Four have decided on their final designs, but they need to decide which materials they're going to use, so they might all have an idea in their mind of what it's going to look like but they've got to decide what materials they're going to use.
Andeep wants to use thin card to decorate it with, Alex wants to use recycled cardboard boxes to actually make the main case, Laura wants to use corrugated card to add strength and separate the different electrical components.
Now, Jun has chosen a recycled cardboard box.
He's actually used his box and turned it inside out, so he's gonna be able to decorate the outside of his box however he wants to do that and secure the parts of the circuit inside.
What tends to happen is when we've got a recycled cardboard box, let's just say for example the same sort of size as a cereal bar box, all of the advertising, the promotional thing, decoration is on the outside, and that's very hard to decorate over.
Whereas if we turn it inside out, we can use the plain cardboard that's on the inside actually on the outside so that we can decorate it and we can make it into whatever we want it to be.
It also means that on the inside we have all of the previous decoration, but actually we can use the inside to store the electrical components carefully together.
Now when he's actually thinking of putting this together, he's actually gonna use masking tape to keep it together temporarily because he's not going to be finishing it yet, he still needs to be able to put the electrical components inside.
But whilst he's doing that, he's just going to hold it together with bits of masking tape.
Masking tape's great because what it means is that you can still paint over it, you can still decorate it, you can use felt tape, you can use all sorts of different things, but actually you can also remove it really easily so that when you are ready to have your box finished and put together, it means you can remove the masking tape and if you wish to glue it, then you can glue it.
Check for understanding now.
Turning a recycled box inside out allows us to.
Is it A, increase the size of the case; B, make the case stronger; or C, decorate the case later? Which do you think it's the correct answer, A, B, or C? That's correct, well done, it's C, to decorate the case later.
Okay, Jun's then planned where the components are gonna go and he's glued some scrap paper labels inside his box to show where they could go.
So what he's actually done is he's thought, "Okay, the battery pack's gonna go here, the micro:bit is gonna go here." You might even want to think about where the wires are gonna go and how they are going to be stored within the box.
This could be on the inside that he's actually going to do this.
You'd less likely to do that on the outside.
You don't have to glue scrap paper labels, you could use post-it notes or you could even draw or label on the box itself.
Now Jun's then thought, how is he gonna keep the electrical components in place? Now, as you can see from the design, he's using pieces of card to actually separate key components.
He's worried that the components are gonna move about and come loose, and so he's got to have a design decision there and think about how he's going to solve this issue.
So he thought about the tools and the other materials he's also going to need.
He's gonna need a ruler and some scissors, he might need some masking tape.
And he's going to use thick card to split the components and hold them in place.
Remember that decision that we had in the last slide? He's thought about that and thought, "Actually, I'm gonna use some thick card and actually separate the components and hold them in place with the card." And he's gonna need to use some thick card also to make blocks on the top to make it look like a chocolate bar.
This is obviously just for his design.
Onto your designs now.
So Task A is thinking about your designs and what sort of materials and resources you're going to need.
So the first thing is choose a box that's gonna be a suitable size for the components.
This could be a small box, could be a large box, it really depends upon what you feel is going to be best and what is going to be available in your school.
The second thing that I want you to actually think about then is, once you've got that box, is turning it inside out and using a small piece of masking tape or perhaps just the flap even, if that works, just to keep it together so you can make sure that it's going to be the right size, it's gonna feel correct.
Lastly, for Task A, discuss and prepare the materials and tools that you need.
So just like Jun did, what I want you to do is to think about the materials you're gonna use, where you're gonna use them, why you're gonna use them, any tools that you might need, and talk about it with someone else about what you're gonna do, really thinking about that plan.
Okay, I'm gonna let you get on now.
So remember, one, choose a box, two, turn it inside out, three, discuss and prepare the materials and tools that you think you are going to need to make your data logger case.
Okay, I bet you've got lots of different ideas now.
Off you go and I'll see you back soon for a bit of feedback.
Welcome back, I'm sure you've got lots of different ideas about all the different materials you're gonna need, the tools that you might require.
And hopefully you've got a box, you've turned it inside out, and we're all ready to get started.
Let's see how Jun's got on.
So he's prepared his box and decided that other materials that he wanted to use.
So some of the things that he's thinking about are, well, firstly, he's concerned that he needs some pens, he needs a pencil and some sticky tack so that when he's trying to make holes for the push buttons, he's gonna be able to do that safely.
Secondly, he's gonna need some scissors to make a hole for the LEDs to be showing through.
And then he's also thought very carefully about separating the battery pack and the micro:bit, and he's gonna use a piece of card to separate those two.
He's gonna use some strips of card to actually hold the micro:bit itself, the component, the key component in place.
And he's going to think about changing the cells is gonna be quite easy if he can open and close the box.
So he's had quite a few design decisions there and he's not even made anything yet, he's just got a box.
But these are pictures of the ideas of things that he's actually considering.
I'm sure you've thought about all of these different things, and if you haven't, maybe that's given you some ideas about design decisions that you're going to have to be making in the next learning cycle.
And here we are, learning cycle two, so we're actually going to be making the data logger case here today.
So these are some resources for making a data logger case.
Now you don't have to use all of these resources.
They're there, it's entirely up to you, but these are some examples of what you may want to use.
So scissors, you're probably very likely to use scissors.
Masking tape if you need it.
Sticky tack and a pencil are gonna be really good to make holes, so making them safely.
A ruler, really important.
Some scrap card, you might want some scrap card to use as well as your box.
And to decorate, you might want to have some felt tips or some paint.
And of course, the most important thing that hopefully you've already got is a range of recycled boxes, and hopefully you've already chosen the box that you need.
Check for understanding.
Which will be the main material that we're going to use to make the data logger case? Is it A, aluminium; B, cling film; or C, cardboard? Which do you think? That's right, nice simple one this one, it's cardboard.
We're mainly gonna be using cardboard today.
The other two materials really aren't gonna be appropriate for what we're actually trying to achieve.
So Jun thought about where the components would go.
So he's thought very, very carefully about where in his case that the components are gonna go and he's used, he's put the micro:bit and he's held it together with some card strips that are attached to one side of the box.
He's then got a card area that's gonna separate the battery pack from the micro:bit.
He's made a hole for the data cable to come through so when he wants to download any new programmes, then he's going to be able to do that.
And he's made holes for the push buttons and a hole for the LED display as well.
Now lastly, he wanted to add finishing touches to his design.
So he's gonna use squares of card to make the box look like a chocolate bar, and he's gonna let it dry before adding the components and checking the circuit.
So today, this lesson today is about making the case, it's not about putting everything inside.
It's about making sure that everything fits, but we're not actually putting everything inside because we might want to paint it, we might want to use felt tips, we might want to use glue and add extra layers to it.
There's lots of different components here that we can actually use to turn this into a really good design.
Check for understanding.
The case will not be glued together yet because.
Is it A, the electrical components still need to be added; B, decoration still needs to be added; or C, the micro:bit hasn't been measured yet? Which is the reason for not glueing the case together yet? That's right, it's because we haven't actually added the electrical components yet.
We're not actually gonna glue everything together until everything is ready.
That's going to be the final stage once the whole case has been completed.
Right, onto Task B for you.
So we've got three sections to Task B, and they're all interlinked.
So the first one is you might want to use pieces of strong card to separate the components in place, create separate compartments.
Two, you need to make holes for the LEDs, buttons and cables.
Of course, if your design is slightly different, then that's absolutely fine.
These are just suggestions.
And number three, use paint, felt tips, scraps of card, or something else entirely, it's entirely up to you and your class what you use to try to finish the case.
You might not want to use any of these.
You might want to just use 1, 2, 3, or something completely different.
It's entirely up to yourselves how you're gonna do this.
There's a lot of making in this task today, so I'm going to let you get on.
We will have some feedback, we'll see some examples that have been completed, and what I'd like you to do is to remember, you need to have some compartments, some holes, and you need to finish the decoration as well.
All right, enjoy, have a lot of fun, and I look forward to seeing the results and working with you and talking to you when we're finished.
Right, so here we go, here's an example.
Jun has actually used strong card to make compartments in the recycled box, and that separated the components out.
He's made a hole for the LEDs, as you can see there, and the buttons.
He just made one big hole, actually, rather than various ones.
And he used scraps of card to make the case look like a chocolate bar.
Now you, I hope, have come up with your own ideas, your own shapes, your own designs, and I'm sure they look different to this.
But essentially inside you hopefully have separated the micro:bit and supported it somehow, and then also created compartments for the battery pack so that it's all nicely and safely gathered, but also remembering you must make sure that you're gonna be able to change the cells as well.
Well done, and that's it for the lesson.
Let's go through a summary and see exactly what we've learned from today's lesson.
So the first thing is that cases need to hold components together safely and securely.
This is really important because when we're using it, it needs to be very secure so nothing drops out.
But also we need to think about the safety of it, and trying to separate the batteries from the micro:bit is a really good idea and good practise.
Secondly, cases need to be finished carefully.
So I'm hoping that when you did get to finish and think about how you're gonna decorate it, how you're gonna make it look aesthetically pleasing, that actually it's going to be done carefully and in a manner where you're really thinking about how it's going to look at the end.
The last key learning point today is that the cases need to have access to the inputs and the outputs of the circuit, so that basically means the outputs of the circuit would be things like the LEDs, so we need to be able to see the LEDs and see the displays that are happening.
And then with the inputs, we need to think about the data cable that goes into the micro:bit.
That's really important so that we can download any programmes onto it.
But also the input, another input for the micro:bit will be the buttons or whatever you've chosen as part of your programme to record the different types of data.
Okay, well done.
Thank you so much for being with me today.
I hope you've enjoyed today's session, I hope you're really pleased and proud of the data logger case that you've produced, I'm sure you've done a fabulous job.
We need to be thinking about installing the electrical component soon.
But until then we need to make sure that everything is dried, everything is sorted, and that you've got all of these different key learning points included within your data logger case.
Okay, thank you ever so much for being with me today and I hope you've enjoyed the session.
I look forward to being with you another time in the future.
And in the meantime, have a great day.
