[upbeat music] - Hi friends.

My name is Cassandra, and these are my helpers.

- Noel and Emory.

- And we're here today to do a fun science experiment with you.

Today we are going to be talking a little bit about blueprints.

Can you say that?

Blueprints.

- [Kids] Blueprints.

- Friends at home, can you say that word?

Blueprints.

Now, do you know what blueprints are?

- Yes.

- Noel, you think you can tell us what blueprints are?

- Yes.

- Go ahead.

- It's like an outline of how the thing will be built.

- Oh, okay.

So when would be a time that someone might use a blueprint?

- A house.

- Oh, okay.

So when someone's building a house, they're going to start with a blueprint and that gives them an idea of what the final house is going to look like.

Is that right?

- Yes.

- Okay.

So today we are going to be using some blueprints.

We're not gonna make a house, but we are gonna make some structures.

And the materials that we are going to use to make our structures are toothpicks, right here we have a bunch of toothpicks and marshmallows.

Over here we have a bunch of different marshmallows.

Okay?

So what do you know about marshmallows?

Noel and Emory, what can you tell me about those?

- It's squishy.

- It's squishy.

So they're probably gonna be pretty good for holding our toothpicks together.

Okay?

So we're gonna use those squishy marshmallows to help make our structures.

Now, when we take a look at a blueprint, so notice how this blueprint is flat.

Do you notice that?

How it's just a flat piece of paper?

- [Kids] Yeah.

You see that it kinda looks like it's a three-dimensional image but it's really just flat, just two-dimensional.

Now when we're talking about the dimensions, you can see that this drawing it's flat.

When we turn this into our structure, it's not going to be flat anymore.

We'll be able to say that that's a three-dimensional shape.

So we're gonna take this two-dimensional, flat drawing and we're going to use our material to turn it into a three-dimensional structure.

It won't be flat anymore.

It will have height and length and width.

And we'll have three dimensions.

So I'm going to use our materials and our blueprint to try to make the first structure.

Okay?

- Okay.

So let's see how many materials I'm going to need to do this.

Can you help me?

- Yes.

Okay.

Friends at home, take a look at our first blueprint.

These little sheets are the marshmallows in our blueprint.

So can we count how many marshmallows we're going to need?

- Yes.

You ready?

Help me count.

- [Kids] 1, 2, 3, 4, 5.

- Five.

We're going to eat five marshmallows.

Okay?

- Okay.

Can you Emory count off five marshmallows for me?

- 1- - Nice and loud.

- 2, 3, 4, 5.

- Great.

Let's just move this over to the side so that everyone can see your marshmallows.

Okay, now let's count the toothpicks.

These straight lines are going to be our toothpicks.

So can we count how many toothpicks we're going to need?

Yeah, can you help us friends at home?

Let's count.

- [Kids] 1, 2, 3, 4, 5, 6, 7, 8.

Eight.

Okay, let's get eight toothpicks.

So Noel, can you count on eight toothpicks for us?

- Yes.

- 1, 2, 3, 4, 5, 6, 7, 7, 8.

- Great.

All right.

So now we have our materials.

Now I am going to try my best to follow this blueprint and make our structure.

So I have four marshmallows, each connected by a toothpick.

Hmm.

Do you think this is gonna work?

Do you think my structure will stay together?

- I wonder.

- You wonder?

- There's sticky so they'll stay.

- You think the sticky marshmallows will keep it together?

- Yeah.

They might.

- Okay.

I'm gonna worried about like keeping it up.

- Okay.

Now we're gonna try to put it together with this marshmallow- - Lift it up.

in the middle.

- I don't think it will work.

- That's the part that I don't think- - You don't think it's gonna work?

- Yeah, I don't think that part's gonna work.

- Ah.

I think it's gonna work.

- Yeah, it might work.

But I'm worried about doing that part.

It might work.

Yeah, it's gonna work.

- Whoa!

- It works!

- No way.

- It works.

Look at our structure.

Look friends in home, we took our blueprint, which was two-dimensional.

It was flat.

And we made it into a three-dimensional structure.

Look, you can see how high it goes.

You can see how wide it is and how long it is.

Wow.

So now, Noel and Emory, do you think you would like to try to make your own structure?

- Yeah.

- Yeah?

All right.

So how about if you go ahead and take the materials and make this structure right here.

Can you try it?

- [Kids] Yes.

- Okay.

Here, I'm gonna help you get your toothpicks.

So we have 1, 2, 3, 4, 5, 6, 7, 8.

1, 2, 3, 4, 5, 6, 7, 8.

Okay.

And we need our marshmallows.

How many marshmallows do we need again?

- [Kids] Five.

- 1, 2, 3, 4, 5.

And 1, 2, 3, 4, 5.

- All right.

Can you go ahead and follow our blueprint and make your structure?

[playful music] move this so our friends can see you working?

[playful music continues] - I built it in the wrong order.

- How does it feel making the structure?

Do you think it's working?

- Yeah.

Mine is working.

- I really can't tell.

- You can't tell?

[playful music continues] Have you ever built a structure before with marshmallows and toothpicks?

- No.

- Make sure you look at your blueprint.

Remember, the blueprint is your design for how you're going to make your structure.

Oh, Noel, looks like he's pretty close.

[playful music continues] Okay.

You ready?

- I have like- - Can you stick- [Noel continues quietly] - your tooth picks in?

- And yay, Emory!

Hold it up and show our friends.

[playful music continues] Yay.

You made your structure.

It looks great.

Noel, can you hold it up and show our friends at home?

That's awesome.

You did such a good job.

That is great.

So you could make another sheet with your toothpicks and marshmallows.

And maybe this is a sheet that our friends at home could try to make if they wanted to make this sheep at home.

Let's count how many marshmallows they need.

You ready?

- [Kids] 1, 2, 3, 4, 5, 6, 7, 8.

- Okay.

Eight marshmallows, and then the toothpicks.

Let's count our tooth picks.

- [Kids] 1, 2, 3, 4, 5, 6, 7, 8, 8, 9, 10, 11, 12.

- All right.

And 12 toothpicks.

So friends at home, if you'd like to try this, you can get 8 marshmallows and 12 toothpicks and try to make a structure just like this using our blueprint.

That's it for now, friends.

Thanks for joining us.

- [All] Bye!
