So let's continue learning about mixtures. A mixture is made when two or more substances
00:00:01
are combined. Mixtures can be homogeneous or heterogeneous. In a homogeneous mixture,
00:00:08
ingredients mix together easily. In heterogeneous mixture, ingredients do not mix together easily.
00:00:18
Here I have an example of each. So here I have orange juice and water. If I've
00:00:25
combined them you will see that it creates a homogeneous mixture where all
00:00:35
of the ingredients are together. Now here in my second cup I have oil and I want
00:00:42
to see will the oil mix with the water and you can see no it does not mix and it floats atop and is
00:00:51
separate. So we can see in this picture number one is a homogeneous mixture and number two is a
00:01:00
heterogeneous mixture. Now let's move forward to exercise six where we will classify
00:01:12
salad, chocolate milk, lemonade, and pizza as either a homogeneous mixture, meaning it can
00:01:21
mix together easily, or heterogeneous, meaning it does not mix together. First, we have number one,
00:01:31
salad. Do you think salad is a homogeneous or heterogeneous mixture? Yes,
00:01:40
it is a heterogeneous mixture because you can see the separate ingredients
00:01:51
such as pepperoni and cheese in the mixture and it is all separate from each
00:01:58
other to the eye. Next, we have chocolate milk, number two. Is that a homogeneous mixture
00:02:07
or heterogeneous mixture? Excellent. Yes, it is a homogeneous mixture, just like our
00:02:17
orange juice with water. When you mix together milk and chocolate, it all combines very easily.
00:02:27
and it becomes one recipe together. So it is a homogeneous mixture. So we will write number two
00:02:38
up here. Next we have three lemonade. Lemonade, like chocolate milk, is also a homogeneous
00:02:47
mixture. So we will write three lemonade in homogeneous mixture. And finally number four
00:02:57
we have pizza. Think of your favorite kind of pizza. Does it have sausage or pepperoni or peppers?
00:03:07
Yes, it probably has different toppings that you can see on top of the cheese, so it is a
00:03:20
heterogeneous mixture. You can write number four over here with heterogeneous mixture.
00:03:29
So here, one more time, to review, we have homogeneous will be one and three, and down in heterogeneous, we will have four and one.
00:03:37
Okay, and that's all that we have for today. Thank you for learning with me and for completing your work, and have a great day. Okay, bye-bye.
