  1. Welcome Second Grade Class • Today we will be learning about the Three States of Matter and density

  2. The Three States of Matter • Gas • Liquid • Solid

  3. Matter • Something that occupies space • Matter is anything made of atoms and molecules

  4. Solids • Has a definite shape. • Does not take the shape of its container. • It also has a definite volume because it can be measured. • Examples: Ice cube, Cookie, Pencil

  5. Liquid • Does not have a definite shape. • It takes the shape of its container. • It does have a definite volume because it can be measured. • Examples: Milk, Paint, & Water

  6. Gas • Does not have a definite shape. • It sometimes takes the shape of its container and sometimes flies freely around you. • These particles are not connected to each other and takes up whatever space is available. • Examples: Oxygen, Helium (balloon), and Water vapor

  7. Density • how much something of a set volume weighs. • Density= Mass/Volume • Example: A block of foam is less dense than a block of lead
