♪ Good morning to a brand new day ♪ ♪ Time to learn and games to play ♪ ♪ Learning things is so much fun ♪ ♪ Learning is good for everyone ♪ (upbeat music) - Hello, little learners.

Welcome back to our learning space.

My name is Miss Lara.

Can you tell me your name?

I'm so happy that you made it back today.

I'm also excited because we're gonna finish off our week of science activities with a very fun experiment called, Exploding Rainbows.

But first, let's sing our song.

Ready?

♪ Hello, how are you ♪ ♪ Hello, how are you ♪ ♪ Hello, how are you ♪ ♪ Let's sing something new now ♪ So we're gonna sing a brand new song that we've been singing all week, and it's called, A Feelings Hunt.

Now you might recognize the song, Going On a Bear Hunt, which is a very popular song.

And if you don't know it, look it up.

You might enjoy it.

But we're gonna go on a feelings hunt instead.

So you're gonna need your binoculars.

Now I made some using a paper towel roll that I cut in half, glued, painted, and added fancy things to, and a piece of yarn to hang.

But if you don't have these binoculars with you, you can also use your built-in binoculars on your hands.

So work your grab, you make circles, and binoculars so you can focus in and see.

We also call those our attentiscopes when we're in school.

All right, let's get started by putting on our binoculars, creating our beat.

It goes like this.

(hands clapping) Can you do a beat for me while we sing, and we'll get started?

♪ We're going on a feelings hunt ♪ ♪ We need our binoculars ♪ ♪ I'm not scared ♪ ♪ Uh-oh, what do I see ♪ A frown and droopy eyes.

Our friend is sad.

♪ Don't tell her to get over it ♪ ♪ You can't hide under it ♪ ♪ But we can help them through it ♪ What do we do when we're sad?

That's right.

We cry, and then we take a big belly breath to feel better.

Ready?

(crying) (deep breath exhale) Breathe.

♪ We're going on a feelings hunt ♪ ♪ We need our binoculars ♪ ♪ I'm not scared ♪ ♪ Look, what do I see ♪ A smiley face and two bright eyes.

Our friend is happy.

♪ Don't tell them to get over it ♪ ♪ Let them enjoy it ♪ ♪ Maybe we can join them ♪ What do we do when we're happy?

We laugh and sing and dance like this.

Ready?

(laughs) And, (deep breath exhale) Breathe.

Last one.

♪ We're going on a feelings hunt ♪ ♪ We need our binoculars ♪ ♪ I'm not scared.

♪ ♪ Look, what do I see ♪ A sad mouth and two very sleepy eyes.

Our friend is bored.

♪ Don't tell them to get over it ♪ ♪ They can't hide under it ♪ ♪ But we can help them through it ♪ What do we do when we're bored?

We yawn, and take a big stretch, and then we breathe to feel better.

Ready?

.

(yawns) (deep breath exhale) Breathe.

Okay, I'm gonna look in my binoculars.

How are you feeling out there?

Ooh, I'm getting a lot of mixed feelings.

Some of you don't wanna be awake.

Wipe the sleep off your eyes.

Now let's go through our visual schedule.

We did our emotional check-in.

We did our feeling song.

And remember, I want you to check-in on how you're feeling throughout the day.

That helps keep your brain strong if you're aware of how you're feeling inside.

And we're gonna finish off our weekly investigation.

Now, last week we did the book, "Thunder Cake," which was all about severe weather.

This week, we've gotten so many scientists that have come and visited us.

We're so famous and popular, and we're gonna finish off with an exploding rainbow activity.

So I'm excited to share that with you.

And then we'll sing our goodbye song.

And we've had time to sing it, but this one might take a little longer, this experiment.

So if we don't, just wave and sing it in your head.

Are you ready for our learning?

This is about the time that we have a (doorbell ringing) we have a special guest.

Let's see who's at the door.

Uh, gotta look my best.

We've had so many famous friends join us.

It's our friends, Anders Celsius and Daniel Gabriel Fahrenheit.

It's about time we had some weather scientists.

Huh?

Now what do you notice about their hair?

The first thing I noticed was that it was white and kind of curly.

So back when they were alive, they actually used to wear wigs a lot.

Some people would even shave their heads and just wear a wig, so that's why they have that kind of hair.

So they were born a long time ago back when we didn't used to have weather forecasts on TV, or even TV.

So back then they had to use other things to predict what the weather was gonna be like.

So Anders Celsius and Daniel Gabriel Fahrenheit both developed instruments and tools that are used to this day to predict the weather.

So they were born in a place called Netherlands and Sweden, kind of around the same area.

So remember, I'm showing you this map and it's flat, but our world is a sphere, so it's round.

And you live in this city, which is the city of Fresno.

That's right, in the United States.

And they lived way across here in Netherlands and Sweden.

Now they developed kind of a modern day thermometer and how we use that.

So these are some older versions that I wanted to show you.

And now of course we have weather satellites.

We have so many satellites in the air that you might even be able to see one if you go out at night.

It would just be like a tiny dot streaming by.

We have weather stations.

So you might look and see in your park, two things, and they collect data on the weather that help our weather people like Kopi, if you ever watch him on TV.

They help him make predictions about what our weather is gonna be like.

And you might notice weather forecast.

So did you think we'd get to a place where we'd be able to know what the weather is gonna be like tomorrow?

It's pretty incredible.

So all thanks to scientists who use their five senses to explore the world around them, their sense of touch, taste, sight, all kinds of things.

And we can do that too.

So today in our science lab, we're gonna be making exploding rainbows.

Let's hope they explode.

Our materials are six empty plastic bottles, dishwashing soap, food coloring, safety goggles, warm water, and active dry yeast.

Now, the reason I added safety goggles to this one is because hydrogen peroxide, which I did not list here, but is one of the ingredients is actually an irritant to your eyes.

So you're gonna wanna be careful when using this one.

You're definitely gonna wanna grownups help.

So what I did is I took my empty water bottle here, and I'm gonna add some hydrogen peroxide.

I'm going to add half of a cup.

So let me put it right here.

Oops, I almost forgot my safety goggles.

I'm telling you to do it, and then I forget.

I always wonder if you're out there kind of telling me, "Miss Lara, what are you thinking?"

So I'm gonna fill up half a cup of this hydrogen peroxide and put it here.

Now this white thing is called a funnel, and it just helps me get stuff inside small spaces like that.

And guess what?

Someone had to invent this.

I'm telling you, you have to just look at the world around you and see how you can be of use.

And then I'm gonna add a few drops of dishwashing liquid like that.

And I'm going, ooh, some bubbles, how fun?

I think that's good luck.

I'm doing science among bubbles.

And I'm going to add red food coloring, because that's actually the first color of our exploding rainbow we're gonna make.

Next, I'm going to take a little bit of warm water and I'm gonna add some yeast.

Now, yeast is something you would normally use for bread making.

So you would use this to make bread.

I'm going to add six tablespoons, because I'm going to add my yeast to all of this.

So I'm gonna add it in.

It's like little granules, and actually this, itself, causes a reaction.

If you notice, when you put it in, it begins to bubble and foam.

So I don't have my story stick, but I have built-in story sticks in my fingers, and I guess I could just use my tablespoon measure here.

I'm gonna give this a good mix so that it incorporates or mixes very, very well.

There we go.

All right, next, I'm going to take my funnel and I'm going to hope that our science activity works.

And, boys and girls, if it doesn't, I'll wait for you to try it at home.

We're gonna put it in there.

Ooh, there it goes.

There's our first color.

Ooh, it's coming out the top, our exploding rainbow.

Now what's the next color?

Orange.

Now, what do we get with those, we have to mix a couple of colors.

We have to mix yellow.

Let's see.

And I have to mix red, and I think that'll make, oh, there it goes.

It's really going all over the place.

All right.

Here's the next color of our rainbow.

Are you ready?

Watch it.

It's gonna explode.

I'm gonna add a little less, and actually that's good.

You can check the amounts.

Here goes the orange.

Next, I'll quickly do the yellow.

That's next.

Ooh, this one had bubbles in there.

There it goes.

Yellow.

I'm gonna add some yellow food coloring.

Now we're making quite a mess, so you'll notice I put a pan underneath to catch all of my spill, or else it would have gone all over the counter, which is not good news, especially for parents that don't want to clean the counter again and again and again.

So, oop, here goes more of their stuff.

Yellow.

Woa, that one came up pretty quickly.

And then we have the green.

I think I'll have time to finish my rainbow.

I'll do the green.

Oh, it's wanting to spill over the pan.

Ooh, I hope it doesn't.

Now, I added a little less there, but it's still going.

Here we go.

Have you ever seen a rainbow outside?

Have you ever wondered why the colors are in that special order?

Now, what's happening here is there's a chemical reaction.

The hydrogen peroxide is reacting with the yeast and it's creating foam, which is what you're seeing come out from the top.

There goes the blue.

Here it goes.

And, poof.

(laughs) Isn't that fun to watch?

The last one is actually a combination of blue and Indigo.

So we're gonna add a little bit of blue and a little bit of red to make some purple.

Now in a true rainbow, I want you to look up.

What would the last color be?

Hmm.

All right.

I think we're gonna have just enough time to finish this last piece.

I hope that it doesn't spill over.

Let's see what color it's gonna be.

There it goes.

Yay.

Oh, this one wants to spill over.

(laughs) My friends here at PBS are gonna be so happy with me to make such a mess.

Huh?

So I'm gonna take my goggles off.

I hope that you enjoyed this experiment, boys and girls.

And I wanna remind you that every day is a good day for science.

Think like a scientist.

Look at the world around you.

Use your five senses.

Explore, ask questions.

I hope that you join me next week for more learning fun.

We're gonna cover Black History Month and we might even have a very special guest.

So until then, Miss Lara's gonna send you a big hug, and a big smooch.

And remind you to read and play and to use your imagination every single day.

We'll see you next time, boys and girls.

Goodbye.
