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.

Matching Match the image with the correct term. *Look back in the notes you just took! Pure Substance Homogeneous Mixture (solution) Heterogeneous Mixture

Classifying Matter- Mini Lab 1)You will be numbered from 1-5 2)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 ecosystem Part 2- Lesson  Describes the properties of a solution  Describes 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 technique 3)Briefly describe why you chose the technique you did.

Beaker 1 You can clearly see brown bits in the water. You see a layer forming at the bottom of the beaker. Beaker 2 You see a blue substance that is clear. There are no suspended particles. Beaker 3 You see a cloudy substance in the beaker but all the particles are suspended and there no particles at the bottom of the beaker Beaker 4 You see two layers formed. One layer is heavier and sinks to the bottom.
