13 Lessons to Teach About the Chemistry of Mixtures and Solutions
Solutions and alloys are types of homogeneous mixtures. 1. Bubble Solution. You can make a simple bubble solution for blowing bubbles by combining liquid dishwashing soap and water, but chemistry holds the secrets to making better bubble solutions that create larger or longer-lasting bubbles.
Chemistry for Kids
A mixture is a substance in which two or more substances are mixed but not chemically joined together, meaning that a chemical reaction has not taken place. Mixtures can be easily separated and the substances in the mixture keep their original properties. Imagine mixing skittles and full size marshmallows, the individual components (skittles ...

10 Module 2, Lesson 2 Grade 7 Science The Magic of Solutions Solutions are a type of mixture in which the pure substances within the solution mix together so well that they give the appearance of only one substance. When sugar is mixed with water, for example, the sugar seems to "disappear." Yet, if you were to taste the mixture, you would

Properties of Mixtures vs. Solutions: Mix It Up!
Teacher demonstration: Set up three glasses of water. Add pebbles of sand to the first glass. Stir the water. Ask students whether this is a mixture or a solution. (Answer: It is a mixture because the sand and the water stay separate. The sand does not disappear in the water.) Add a teaspoon of salt to the second glass.

Use one of the coloured pens to make a 0.5 to 1 cm ink spot in the centre of the disk. Lay the paper disk flat over the top of a beaker. Place a drop of water in the centre of the ink spot. Add another drop of water every minute or so to make the chromatogram spread toward the edges of the paper disk.

5. All particles are attracted to one another. Your quiz this week will again be based on the particle theory. 1. You will be asked to identify substances as "pure substances", "heterogeneous", or "homogeneous" based in drawings of groupings of particles. 2. You will be required to explain the reason for your answers.
