Does It Mix Well?

Contributor: Kaitlyn Aston. Lesson ID: 12678

Admit it: You've played in the mud before! What makes mud? Water and dirt! What takes off mud? Soapy water! What do dirt and soap have in common? Check in with Flo to learn about solutes and solvents!

Imagine you are mixing up a nice cup of lemonade, only to find out that the dry lemonade mix and the water will not mix together. To your surprise, the chunky lemonade mix will do nothing but simply sit on top of the water. How disappointing! What is going wrong here?

In the previous Water lesson, Exploring Water with Submarines!, you learned that water can cause a submarine to either float or sink, based on how much water or air is in the ballast tanks of the submarine.

Oceans and seas offer submarines the ability to travel for miles underwater and undetected.

Most of the water in the world is salt water, such as the ocean water. Salt water, as you may have guessed by now, is a mixture of both salt and water. Ever since the creation of the earth, a lot of mixtures have been made with a variety of materials and water. Here are a few examples:

  1. When you take a bubble bath, you mix soap with water to make big, foamy bubbles.
  2. When you make something like Jell-O or lemonade, you need to dissolve or mix the powder in the water.
  3. When an adult makes coffee or tea, they are mixing coffee grounds or tea bags (or leaves) with water.
  • Can you name anything else that is made by mixing a material with water?

Think about construction sites and restaurants and other places.

It seems like water is a part of some of the most common mixtures in the world, doesn't it? Think about what would happen if something DIDN’T mix with water. Join Flo to find out when this might happen:

 

Thanks, Flo! As you saw in the experiment, water is capable of creating solutions with certain items. This is because water is considered a solvent — something that can dissolve other materials. Components that can dissolve in water are called "solutes." When you combine water (the solvent) with a dissolvable material (the solute), they are able to create a solution! The materials from the experiment that mixed well with the water in order to make a new solution were the food coloring and the sand. However, not everything can dissolve in water.

  • Do you remember what two materials from the lesson did not mix well with water?
