- Hi friends, how are you today?
We are so excited today to not only read this amazing book with you, but also we're gonna have a chance to do a science experiment.
So I am so excited to get started.
So my name is Katherine and I have a special guest today.
- I am Genevieve.
- She's Genevieve.
Are you ready to read this book?
The name of the book is, "A Ray of Light", and the author is Walter Wick.
So let's get started.
And our front cover, we already see this beautiful colors that are found and we see the, what colors do you see, Genevieve, actually?
- Red, orange, yellow, green, blue, and purple.
- I love that song!
- I mean indigo.
- Indigo.
- And then violet.
- Oh, it's indigo, violet hue.
So I love that song.
Red, orange, yellow, green, blue and purple.
Or indigo, right?
Indigo, violet.
So let's learn a little bit more about light.
What is light?
Everything from the earth beneath our feet.
The water we drink and the air we breathe is made of atoms.
Atoms are tiny, invisible building blocks of matter.
Matter can be a solid, liquid, or gas.
And matter is the faces of everything we see, feel, smell, or touch.
What about light?
What is it made of?
How does it fit alongside everything else in the world?
Light is energy.
If you rub two hands rapidly together, the friction will warm your hands.
Give it a try for yourself.
Let's rub our hands.
Rub, rub, rub!
Ooh!
- It's getting really hot and is steaming warm!
- It's getting very hot.
It's feeling very steamy.
So this tells us that light is energy.
And although light is neither of solid, liquid, nor gas, all three kinds of matter can have a role in its creation.
Our match has lit the candle, the melting wax travels up the wick and provides more fuel to the flame.
Wow, that's amazing.
And we also have light waves.
Look at these light waves.
Light travels in waves.
Because waves of all kinds share similar behaviors.
We can look to water waves to help us understand the wave behavior of light.
And there's also a light obstacle course.
What are you seeing here, Genevieve?
- Light going across shapes.
- Light going across shapes.
So it says here, unless obstructed or reflected, light travels in perfectly straight lines.
Above, a ray of sunlight, like in this picture we're seeing comes in straight from the left.
But then it bends down slightly and up again, continuing on a straight path.
Hmm, so it looks like because it moves, it went into a different trajectory, a different path.
- This what the picture that's on the front!
- Yes, this picture on this page is called the color spectrum.
- It's so beautiful!
- And it's just like the picture in the front cover of this book.
- It's so beautiful!
- It is beautiful.
It reminds me a little bit of a rainbow because of the bright colors we're seeing and.
- And a alicorn, that's beautiful, that's rainbow.
- So beautiful.
So here it says, there's a brilliant and vivid color that is refracted by a simple glass prism.
And the full range of the sun's colors are spread out.
So you can see all the colors of the rainbow, red, orange, yellow, green, blue, indigo, and violet.
Each color has a different wavelength.
Oh my goodness, look!
This is actually very similar to the experiment we're gonna do in some way.
So it's gonna show us a vanishing color trick where it says overlapping red, green, and blue light will appear as white.
But what color is made from overlapping just red and green light?
Hmm, so when you mix red and green paint, you might be surprised that red and green light make bright yellow.
So this talks all about the different kinds of color tricks that exist when mixing lights.
So actually our experiment is gonna be.
- And if you mix a dark color with a very light color, then I'll make that color even lighter.
- Yes, absolutely.
- Like blue and white will make light blue.
- Oh yeah, so like you make dark blue with like white and might make light blue.
- And pink like with white will make it even, even beautifuller - Pink and white might make a different color.
Makes it even more lighter actually.
- Yeah, and more beautiful.
- So, you know what?
We're actually gonna be discussing the mixing of like pigments, but also the mixing of liquids.
So we're gonna be doing that in a little bit.
But first, let's look at nature's shimmering color.
What are some of the different colors that we find in nature over here, Genevieve?
- What's on the top I think are insects.
- Yeah, so, friends, are you seeing these insects along with us?
See, I see a beautiful butterfly and it's color is amazing.
Can you guess that color?
- [Genevieve] And that beetle!
- [Katherine] The color is blue.
It has a beautiful teal blue and.
- [Genevieve] And a little beetle glowing on the leaf.
- [Katherine] Yes, on the leaf.
And it's this like glowy and shimmery teal, maybe greenish color.
- [Genevieve] Yeah, and on the side, it's a little pink color.
- [Katherine] Yeah, a little purple.
So, you see a little violet in there.
Feels like the peacock feathers down here on the lower left.
And the seashell on this side.
- It's a scallop!
- Oh, that's a scallop?
Oh, I'm learning something new today.
And you can see the shimmery glowy colors that you, we see in this particular scallop.
Okay, so wow, we're getting to pigments, but within pigments, here, it doesn't really, it shows us about how we can mix colors by using these pigments and grinding them up to get them from a couple of nature.
- I think I know.
- Yeah?
- There's a little dirt and then we color them.
And then we color the paint.
And then we crumble it on the light and then over time it turns that color.
- Yeah, so it actually tells us that pigments, along with related liquified colorants called dyes can be derived from plants or animals.
And many are extracted from the earth.
Still others are made from synthetic chemicals.
So these pigments, they come from nature, but they're also manmade.
Now that means they're also produced by us as humans.
So as we go through the rest of the story and we take this gallery walk, we can see the beautiful kinds of ways that light take part in our earth.
We see light when it comes to the sun coming up and down.
- [Genevieve] Of course, it is!
- [Katherine] We also see light in, when we look at how big and grand the sun is.
- Oh that's too grand for me.
- Oh, it's so grand, right?
What we see is from outer space, we can see the planet in outer space along with the moon and the light.
- [Genevieve] Okay and don't forget the light up there!
- Oh yeah, and lights that we have in everyday.
Light, like the light bulb that's shining on us right now.
For today, we're going to do some mixing of colors, actually.
And then I'm gonna take a flashlight and we're going to see if we can look at the light passing through the cup.
So Genny, do me a favor.
Can you fill this water cup?
I simply grabbed a clear cup, put some water in it from this sink faucet.
So put blue just here.
Genevieve is gonna help me put blue here.
That's perfect.
And I'm putting green in the middle cup.
- Can I do the other?
- And then the last one will be yellow.
So we have green, blue?
And then now we're gonna put some yellow in the last cup.
- Can I shine the light?
- Absolutely.
So let's do some yellow.
Okay, so here we have yellow, green, and blue.
And we're gonna see where the light shines through the most.
Can you see the light shining through on the other side, friend?
Well, as you can see, my hand on the other side has this yellow hue as I shine the light through it.
- [Genevieve] I wanna do that.
- Can you see on the other side?
- Ooh!
- Oh, you're experimenting with all of that.
So what I'm thinking we can do too, is if I put a white piece of paper, you can be able to see it a little bit better.
So here we have the blue liquid.
Here we have the green liquid, and then the yellow liquid, which seems to shine in.
Which one seems to shine in more, like to the other side?
What do you think, Genevieve?
So we have the yellow, the green, and the blue.
Yellow, green, blue.
I think the yellow one seems to shine through the most.
I wonder if it's because it's a lighter liquid and the light is able to shine past it even better.
What do you think, Genevieve?
- I think that's the one.
- You think that's correct?
[giggles] - Yeah.
I think if we had a spoon and we stirred them, it would make them, the others even lighter if we mix them.
- Okay, oh, that would be interesting it we mix them.
They might even get even darker.
That's something that you can definitely try at home.
So thank you so much for joining us today.
Have a great rest of your day.
Bye, friends!
- Bye!
