Warm up
  • What is the methods portion of a lab report include?
warm up answers
Warm up answers
  • The steps or procedures to perform a lab.
today s activities
Today’s activities
  • Complete metal v nonmetal lab report
  • Notes
  • Partner activity- 10 heterogenous and homogeneous mixtures
water is a form of matter
Water is a form of Matter…
  • Matter- anything that occupies space and has mass. Can be a :
    • Solid
    • Liquid
    • Gas
pure water
“Pure” Water
  • Because many substances readily dissolve in water, we call those aqueous solutions. Even “pure” water has dissolved minerals and gasses in it!
  • Pure water is clear, colorless, odorless, and tasteless
mixtures
Mixtures
  • Mixture: when 2 or more substances combine, and yet the substances retain their individual properties (they can be separated by physical means like filtration or adsorption)
two types of mixtures
Two Types of Mixtures

1. Heterogenous

2. Homogenous

A mixture that is uniform all throughout

  • A mixture who’s composition is NOT the same all throughout
heterogenous mixtures
Heterogenous Mixtures
  • Suspension: when solid particles are large enough to settle out through filtration
    • Ex: coffee grounds & water
  • Colloid: when small particles can not be filtered out
    • Ex: milk
homogenous mixtures
Homogenous Mixtures
  • Solution: consists of a solute (the dissolved substance) and a solvent(the dissolving agent [substance doing the dissolving])

Solute: powder

Solvent: water

  • Give an example of a solution and an example of a mixture.
