Earth Science Week 5
Vocabulary: Unit 8 Continued
-
Almost no new words for this week so no Vocab list
-
When you are done pick one word and write a one-page paper on that word.
You will be watching some video’s and activities for the week. You will show me what you have done by emailing me a picture.
Make sure you try the activity.
We are continuing our discussion about water.
-
As you all know water on our planet can come in 3 states.
-
Solid, liquid or gas are the three states.
-
When H2O changes from state to state the actual atoms don’t change. This is called conservation of matter.
-
But what about other items that change their state does anything happen to the actual atoms or do they stay the same?
-
This is the basic question we are going to work on today.
Day 1
Video: Solution, Suspension and Colloid
-
How do you know if something is a solution, suspension or colloid?
-
What is the difference between homogeneous and heterogenous?
-
What is the Tyndell effect?
-
Who was Tyndell?
Day 2
Video: Tyndall Effect - Why does the sky appear blue?
-
How does the Tyndell effect from day one and day two connect to each other?
-
If your color blind what does that mean in regards to the Tyndell effect?
Day 3
Video: Scattering of Light & Tyndall Effect
-
Try to create a suspension, a solution, and a colloid.
-
How do you know which is which?
Days 4/5
-
Last week we learned about filtering water as part of the water cycle.
-
This week we learned that when other elements are in the water they will be solutions, suspensions or colloids.
-
Write a short paper on how these two ideas are connected.
-
How would you use this information if you were in charge of the cities water system?
