Which of the following are substances?
Which of the following are substances?
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!

Sydnie is making a sand castle on the beach. She mixes water with her sand to make sure it's wet enough to mold into the shapes she wants. Is Sydnie making a new substance when she mixes sand and water? How do you know?
Sydnie is making a sand castle on the beach. She mixes water with her sand to make sure it's wet enough to mold into the shapes she wants. Is Sydnie making a new substance when she mixes sand and water? How do you know?
The answer is "No, Sydnie is not making a new substance because only the shape of the sand and water changes."

What is a mixture?
What is a mixture?
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.

True or False: A mixture involving liquid cannot be separated.
True or False: A mixture involving liquid cannot be separated.
Many people have the misconception that once a substance has been mixed into a liquid that it cannot be separated. When something like salt is stirred into water, it seems to disappear, so the thought of separating it can be hard to imagine. There is no way to sift the salt out or remove the salt pieces with forceps. If the water is set in the sunlight, it will begin to evaporate and leave behind the salt that was mixed in.

Students in a science class mix together pepper and water. What type of change is made to materials when they are mixed?
Students in a science class mix together pepper and water. What type of change is made to materials when they are mixed?
The students in the class created a new substance when they mixed the water and pepper, but the change is only physical. The pepper can be separated from the water, and there is no permanent change to either substance. There was no change in smell or color, and no new substance was formed as in a chemical change.

Separating a mixture is a way to reverse the creating of something new. If sand and rocks were mixed, a mixture was made with the two substances. It can be changed, and the mixture separated if the stones and sand are sifted. The small grains of sand will fall through the sifter leaving the rocks on top and separated.
