Organization of Matter

Scientific Terms- Defined

• Pure Substance: Contains only one type of particle. • Homogeneous Mixture (solution): Made up of at

least two type of particles. The particles are distributed evenly throughout the mixture. To the naked eye there appears to be only one substance• Heterogeneous Mixture: Made up of at least two

types of particles. The particles are not distributed evenly throughout the mixture. At least two different substances are visible to the naked eye.

Classifying Matter- Mini Lab

1) You will be numbered from 1-52) All the 1’s will be in a group, all the 2’s will be in a

group etc. 3) Each group will be given a container 4) The group is responsible for deciding what category of

matter the substance in the container belongs too Heterogeneous mixture Homogeneous mixture Element Compound 5) Each group will rotate through all the containers

Learning Intentions

By the end of the class I will be able to:Part 1- Bill Nye Understand the role of marshes in an ecosystemPart 2- Lesson Describes the properties of a solutionDescribes the properties of a mixture Distinguishes between a solution, a homogenous

mixture and a heterogeneous mixture

Let’s Practice

You have been asked to identify some substances in beaker in a lab. Before you are able to identify the substances you have to separate the mixtures. You will need to:1) Identify the type of mixture to be

separated.2) Choose a separation technique3) Briefly describe why you chose the

technique you did.

Beaker 1You can clearly see brown bits in the water. You see a layer forming at the bottom of the beaker.

Beaker 2You see a blue substance that is clear. There are no suspended particles.

Beaker 3You see a cloudy substance in the beaker but all the particles are suspended and there no particles at the bottom of the beaker

Beaker 4You see two layers formed. One layer is heavier and sinks to the bottom.
