Looking at igneous rocks

Our investigation led us to examine 5 different igneous rocks. In your groups you classified them into 2 separate groups. On Monday we will learn how scientists classify igneous rocks and we will also look at volcanic ash.

Stay warm and have a great weekend!

Quiz time!

Productive day today:

• Took a quiz on volcanoes
• Completed a rock cycle diagram in notebook
• Had a chance to work on HW and MOS in class.

Homework:
Read pgs 258-263. Choose 1 summary to write:

• How do scientists monitor Mt. St. Helens?
• Discuss the reappearance of plant and animal life after the eruption.

Reminder: 3 MOS logs are due tomorrow!

Riding the Rock Cycle

What is the big deal about rocks? Well without them we would not have a lot of common items we use everyday (roads, jewelry, cement, building materials, even makeup!).

We observed rocks from each of the three types: sedimentary, metamorphic and igneous. Then we became took a ride as a mineral in the rock cycle.

Homework: Complete rock cycle cartoons. Quiz is tomorrow!!

Types of Volcanoes

Volcanoes can have different sizes and different shapes. We looked at how 3 types of volcanoes can form. We also used our cell phones to text our answers during our review on volcano types. Be sure to study the volcano type chart you did in class.

For those interested in the website I used: http://www.polleverywhere.com/

Homework: Complete Volcano ID worksheet. If you get stuck, go back in your notes/book.

QUIZ IS NOW THURSDAY!! KEEP STUDYING

MOS ideas

Halfway through the 2nd marking period means your MOS logs are due. Need some ideas? Here are a few.

• Remember the 5 questions for a volcanologist you created for homework? Answer them by going to the USGS website. If you can not find the answer to your question, send an email to the USGS. Click here for directions.
• Create a model of one of the types of volcanoes we learned in class.
• Use vocabulary from this unit and create a crossword puzzle.
• Check out the class library (by the window) with simple activities to do.

How liquids flow

The term for this is viscosity. We used the data from our lab on Friday and applied the concept of viscosity to lava. Be sure to review your notes on properties of magma.

Having a hard time remembering viscosity? Remember this:

• Hallway packed with students (hard to walk through) - high viscosity (liquid doesn't move as freely)
• Hallway with only a few students (easy to walk through) - low viscosity (liquid moves feely)

Homework tonight: Create a list of 10 liquids. Order them from highest viscosity to lowest viscosity.

Reminder:

• 3 MOS logs due Friday
• Quiz Wednesday on volcanoes, viscosity and type of volcanoes
