Matter and Atoms, Chapter 9, Lesson 1, Substances and Mixtures Lesson Outline
What is matter?
Anything that has mass and takes up space.
The substances that make up a solution are ____________?
NOT bonded together, so adding more of one substance in a solution will NOT change the composition of the solution
What is matter made of?
The building blocks of matter are small particles called atoms.
What is matter NOT?
Types of energy, including heat, sound, and electricity, and forces such as magnetism and gravity are NOT matter.
What is a homogeneous mixture?
a mixture in which two or more substances are EVENLY mixed, but NOT bonded together
What is a heterogeneous mixture?
a mixture, such as trail mix, in which the substances are NOT evenly mixed
