5th Grade Science › Creating Something New Via Mixture
What is a mixture?
A combination of two or more substances
The one thing that will be changed to be tested in the experiment
A controlled condition where variables are explored to determine an outcome
A measure of the total area that the surface of an object occupies
Explanation
A mixture is when two or more substances are combined to create something new. The substances can remain separate like a salad or trail mix, but still, something new is formed. Another type of mixture is a solution when one substance dissolves into another like salt being stirred into water.

Which of the following are substances?
all of these
none of these
wood
water
chemicals
Explanation
The answer is "all of these."
A substance is anything that takes up space and has mass. Substances can exist in solid, liquid, and gas form. When you mix two substances and you might or might not create something new, and it all depends on what two substances you are mixing. Ripping, tearing, smashing, stirring, squishing, and changing the shape of a substance by mixing it with another is called a physical change. Chemical changes occur when a new, third substance is created by combining two substances. Signs of a chemical change include, release of heat, bubbles, a color change, and smells!
