  1. 5th Grade Science Mrs. LaRosa Matter Study Guide www.middleschoolscience.com 2008

  2. Matter • Anything that has a mass and a volume

  3. States of Matter Solid Liquid Gas Plasma Close up view of atoms and their behavior Animated images are from http://www.chem.purdue.edu/gchelp/

  4. Physical vs. Chemical Change • Changing from one state to another is a • Physical Change. • If a new substance is formed it is a • Chemical Change. Images are from http://www.chem4kids.com

  5. Atoms • The building blocks of Matter • Consists of Protons (+), Electrons (-), • and Neutrons (N). Elements • Consists of only one kind of atom, • Cannot be broken down into a simpler type of matter by either physical or chemical means • Can exist as either atoms or molecules. Images are from http://www.chem4kids.com

  6. Molecules • A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. • In the animation above, two nitrogen atoms • (N + N = N2) make one Nitrogen molecule .

  7. Compounds • Atoms of two or more different elements bound together. • Can be separated into elements chemically, but not physically. In the animation above, water (H20) is a compound made of Hydrogen and Oxygen. Animated images and notes from http://www.chem.purdue.edu/gchelp/atoms/elements.html

  8. Solutions • Solutions are groups of molecules that are mixed up in a completely even distribution. Homogeneous • Uniform Distribution. • Example: Sugar and Water Images are from http://www.chem4kids.com

  9. Solute • The substance to be dissolved. Solvent • The one doing the dissolving. Images are from http://www.chem4kids.com

  10. Making a Solution

  11. Colloids • Particle sizes are in between the size of particles found in solutions and suspensions . • Can be mixed and remain evenly distributed without settling out.

  12. Mixtures • They are substances held together by physical forces, not chemical. • Can be separated physically. • Solutions are also mixtures. Heterogeneous • The substances are not uniformly mixed. • Example: Sand in a glass of water. Images are from http://www.chem4kids.com

  13. Mixtures Suspensions • Are heterogeneous mixtures consisting of parts • that are visible to the naked eye. • Substances will settle over time. Example: the ingredients in salad dressing

  14. End of the Matter Study Guide Next Study Guide will be “Periodic Table”
