Dec 14, 2016 · How to communicate the answer to the key “Question of the Week”? I asked “When you mix things together, do they always combine into one new thing or do they stay separate? Let me show you an experiment, and we’ll see.” I started with a demo of oil and water.

A mixtureis 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 and mar...
You can make your own mixtures with items from around the house. 1. Firstly try to make a mixture of toys. 2. This time use cereals or sweets.
A solution is made when a solid (which we call a solute) dissolves into a liquid (that we call the solvent) One example of a solution is salt dissolved in water. The salt and water can be separated again by evaporation ( the water will evaporate if left in a hot place leaving he salt behind ).
Aim: To test out these three mixtures to see which form solutions and which don’t 1. Salt and Water 2. Sugar and Water 3. Sand and Water Results Table You should find that both salt and water and sugar and water dissolve and form solutions and that sand sinks to bottom!
Can you separate the components out of the mixture again? Hint – to separate the sand from water you could use a sieve. This is possible as the sand is insoluble ( doesn’t dissolve in water ). Salt and sugar are soluble ( dissolve in water ) and can be separated by evaporation. Another way to separate a mixture is by using a process called chromato...
Rock salt is a mixture of salt and sand and is often spread on roads in winter to stop cars skidding.
The solution of water and rock salt should be passed through the filter paper where the sand ( which will not have dissolved in the water ) will collect. Salt does dissolve in water and so will pass through the filter paper.
To separate the salt from the water the water needs to be evaporated off, either by leaving the salty solution in the sunshine or placing under a heat source. The salt will form as crystals – this process is called crystallisation. Last Updated on May 24, 2021 by Emma Vanstone
Pour a small amount of two different liquids together into one cup and mix them together with a clean spoon. What happens to the liquids? Did the two liquids become one new liquid, or do they remain separate liquids and form layers? Do they change colour, texture, smell, foam up, etc.?
Sep 1, 2023 · As they investigate the chemistry of mixtures, they learn about hydrophobic, hydrophilic, and immiscible properties; solvents and solutes; solubility and saturation; phases; the Tyndall effect; and how mixtures are related to real-world challenges and solutions.
May 1, 2024 · Mixing two solids, without melting them together, typically results in a heterogeneous mixture. Examples include sand and sugar, salt and gravel, a basket of produce, and a toy box filled with toys. Mixtures in two or more phases are heterogeneous mixtures.
Sep 20, 2022 · A mixture is a combination of two or more substances in any proportion. This is different from a compound, which consists of substances in fixed proportions. The substances in a mixture also do not combine chemically to form a new substance, as they do in a compound.

What is mixing it up?
It all has to do with a concept called miscibility and another important factor called density. Miscibility describes how well or how easily two liquids mix together. Some liquids, like orange juice and water, mix together easily and become a special kind of mixture called a homogeneous mixture.
