Homework: Picture scavenger hunt

2. Last class we learned some ways to describe matter – physical and chemical properties Today we will look at how matter is classified.

4. Mixtures
Matter that has a constant composition and constant properties throughout a given sample are called substances Combining two or more substances gives you a mixture.

5. 5 4 3 6 7 2 1 8 Mixing Stations Follow the directions at each station
You’ll have apprx 7 minutes at each station so work dilligently! 3 6 7 2 1 8

6. Station 1: Identifying the different types of mixtures: Homogeneous mixtures and Heterogeneous mixtures
Station 2: Making different types of mixtures: Create a homogeneous mixture and a heterogeneous mixture using the materials provided
Station 3: Separating mixtures: chromatography
Station 4: Separating mixtures: Filtration

7. Station 5: Separating mixtures: Distillation
Station 6: Separating mixtures: Quizlet quiz If you can beat my score of 45 seconds you’ll earn extra credit!
Station 7: Separating mixtures: Magnetism

8. Station 1: Identifying Homogenous and heterogeneous mixtures
Discuss in your group the differences between homogenous and heterogeneous mixtures. Then identify which of the solutions in front of you are homogenous and which are heterogeneous

9. Station 2: Making mixtures
Using the materials in front of you make a homogenous mixture and make a heterogeneous mixture Make sure that you record what combinations made homogenous mixtures and what combinations made heterogeneous mixtures. Also, clean up for the next group!

10. Station 3: Separating mixtures: chromatography
What is chromatography?
Use the materials in front of you to separate the substances in the inks of various pens and markers.
What markers separated into the most substances?
What do you think this means in relationship to the ink composition? Is there more ingredients or less in the pens that you tested?

11. Station 4: Separating mixtures: Mechanical filtration
What is mechanical filtration?
With the materials in front of you, find a way to separate the mixture by mechanically separating the substances or by filtering the substances from each other

12. Station 5: Separating mixtures: Distillation
Observe the apparatus. This is showing the process of Distillation
After observing the apparatus, what do you think distillation is?
How is this a method to separate mixtures?

Homework: Picture scavenger hunt

15. HW: Picture scavenger hunt Monday Night at 11PM
Take a picture of the most unique homogeneous mixture and the most unique heterogeneous mixture and upload them to the class’ Google Drive. Make sure that you put your name somewhere in the picture!
