1 00:00:01,250 --> 00:00:08,929 So let's continue learning about mixtures. A mixture is made when two or more substances 2 00:00:08,929 --> 00:00:18,129 are combined. Mixtures can be homogeneous or heterogeneous. In a homogeneous mixture, 3 00:00:18,129 --> 00:00:25,890 ingredients mix together easily. In heterogeneous mixture, ingredients do not mix together easily. 4 00:00:25,890 --> 00:00:35,509 Here I have an example of each. So here I have orange juice and water. If I've 5 00:00:35,509 --> 00:00:42,030 combined them you will see that it creates a homogeneous mixture where all 6 00:00:42,030 --> 00:00:51,009 of the ingredients are together. Now here in my second cup I have oil and I want 7 00:00:51,009 --> 00:01:00,770 to see will the oil mix with the water and you can see no it does not mix and it floats atop and is 8 00:01:00,770 --> 00:01:11,489 separate. So we can see in this picture number one is a homogeneous mixture and number two is a 9 00:01:12,049 --> 00:01:19,969 heterogeneous mixture. Now let's move forward to exercise six where we will classify 10 00:01:21,010 --> 00:01:31,150 salad, chocolate milk, lemonade, and pizza as either a homogeneous mixture, meaning it can 11 00:01:31,150 --> 00:01:40,310 mix together easily, or heterogeneous, meaning it does not mix together. First, we have number one, 12 00:01:40,310 --> 00:01:51,060 salad. Do you think salad is a homogeneous or heterogeneous mixture? Yes, 13 00:01:51,060 --> 00:01:58,700 it is a heterogeneous mixture because you can see the separate ingredients 14 00:01:58,700 --> 00:02:07,340 such as pepperoni and cheese in the mixture and it is all separate from each 15 00:02:07,340 --> 00:02:17,039 other to the eye. Next, we have chocolate milk, number two. Is that a homogeneous mixture 16 00:02:17,039 --> 00:02:27,770 or heterogeneous mixture? Excellent. Yes, it is a homogeneous mixture, just like our 17 00:02:27,770 --> 00:02:38,629 orange juice with water. When you mix together milk and chocolate, it all combines very easily. 18 00:02:38,629 --> 00:02:46,069 and it becomes one recipe together. So it is a homogeneous mixture. So we will write number two 19 00:02:47,030 --> 00:02:57,189 up here. Next we have three lemonade. Lemonade, like chocolate milk, is also a homogeneous 20 00:02:57,189 --> 00:03:07,590 mixture. So we will write three lemonade in homogeneous mixture. And finally number four 21 00:03:07,590 --> 00:03:18,789 we have pizza. Think of your favorite kind of pizza. Does it have sausage or pepperoni or peppers? 22 00:03:20,469 --> 00:03:29,189 Yes, it probably has different toppings that you can see on top of the cheese, so it is a 23 00:03:29,830 --> 00:03:37,349 heterogeneous mixture. You can write number four over here with heterogeneous mixture. 24 00:03:37,590 --> 00:03:59,009 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. 25 00:04:00,449 --> 00:04:10,530 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.
