My wife is a preschool teacher. She wants to setup a display to show how colors mix to make new colors.?

Question

She would like to put two liquids with different viscosities and with different colors in a plastic bottle so that, when shaken, it will turn to the color of the mixture but will separate out again into the individual colors. For example, she would like to have one liquid yellow and a second one blue so that when shaken, the mixture turns green. After some time, the liquids would separate and return to their original colors until shaken again. She saw such a mixture in a store a few years back but was not teaching at that time and she can't find them again. Any help would be greatly appreciated.

Answer 1

One really cool way to do this is with white carnations (and it's a little less messier). Get 6 white carnations. In 3 vases, place food coloring of red in one vase, yellow in another and blue in another - these carnations will turn these colors. To make the carnations orange, purple and green, simply mix the correct food coloring drops (usually on the back of the box of food coloring) to make the carnation turn that color - it's also a great science experience.

I haven't heard of what you are describing - I don't know if you could use oil and water for the mixtures (that's the only thing that I can think of, but I don't know how you would color the oil - maybe mineral oil?)

Answer 2

think the best way to let all children learn the shapes, is to let them play with the shapes. I use building blocks, attribute blocks, felt shapes, clay and any art supply I can find. Always call the shapes by the correct name. As you play with the children, talk about the attributes. Let the children go on trek around the school in the search for the shapes. Talk about the shapes and give them the language they need to understand the concept of shapes. Let the parents know what shapes they are learning about in class. At home, they can look for examples and bring them to school. The children can have a little shape museum set up where all of their treasures and finds can be displayed. There are many songs that you can find on the web to sing. Children love shapes. They are something that the children can actually manipulate and draw.
I have listed a few of my favorite sites, but they are by no means the only ones. I hope you and your children have a fun time learning together.

Answer 3

I don't know about the liquids, but I teach colors with balls of play-do. Start with the three primary colors, then give the kids two different colors to play with. In a few minutes, they have mixed them together to create a secondary color.

Answer 4

You can always use food coloring in clear water bottles.

I think I was taught with primary colors on an over-head projector. That way everyone can see from their seats and when you overlap the colors you can see what the mixture is.

Answer 5

The liquids sound great. I used cellophane wrap in only primary colors cut in squares.When you over lap two colors they change colors.

Answer 6

Answer 7

I think they still sell that at "The Teacher's Store" - I don't know if they have one around you.

Answer 8

You can color baby oil and water and it will do this...good luck!
