1 Refresh – Answer this Review Question in your science notebook Match the following genotypes with an example 1. Homozygous dominant A. Pp 2. Heterozygous B. pp 3. Homozygous recessive C. PP PPPp pp

2 Set – Get ready for todays learning activity List the mixtures from the jars lab & discuss how you could determine that each were mixtures. Hint: Look back at your science notebook for the Jars Lab activitiy.

3 Now…Take notes on todays lesson. Different Kinds of Mixtures There will be lots of new vocabulary today that you will need to remember. Follow along with the note- taking guide. At the end of the lesson, you need to be able to explain the differences in the types of mixtures discussed in the lesson and give an example.

4 Mixing it up With Mixtures 8 th Grade Science Use with Note-taking Guide Questions & Lesson Guide for Mixture Lesson

5 They are substances held together by physical forces, not chemical. Can be separated physically. Solutions are one kind of mixture. + =

6 Solutions are mixtures of two or more substances that are spread out evenly. Example: salt - water solution

7 The substance to be dissolved. (salt) The substance doing the dissolving. (water) Images are from

9 Concentrated means strongConcentrated means strong examples; frozen orange juice in a can, powdered milk, can of soda, examples; frozen orange juice in a can, powdered milk, can of soda, Diluted means weakDiluted means weak examples; orange juice mixed in jug with water, powdered milk mixed with water, soda in melted ice examples; orange juice mixed in jug with water, powdered milk mixed with water, soda in melted ice Concentration of Solutions

10 Solutions are homogeneous mixtures Because they look the SAME throughout the mixture.

11 Uniform Distribution (cant pull stuff out) Example: Sugar and Water

12 The substances are not uniformly mixed. (can pull pieces out) Example: Sand in a glass of water.

13 Are heterogeneous mixtures consisting of parts that are visible to the naked eye. Example: the ingredients in salad dressing Substances will settle over time. Directions: Shake well before using.

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

15 Colloids are homogeneous mixtures Because they look the SAME throughout the mixture.

16

17 Assess – How much did you learn? Name the 3 kinds of mixtures? How can you tell the mixtures apart? How is their appearance different? Give an example of each.
