Today we took a summative on Continental Drift.  After the summative we completed a directed reading worksheet.  The reading is posted below for those who did not complete the worksheet in class.  Please also write the notes on Plate Tectonics on your next clean page in your notebook.  Notes are posted after the reading.

Today students are reading an article on Alfred Wegener and completing a worksheet on the evidence that he and other scientists accumulated to support the idea that continents have moved.  Students should be able to describe Continental Drift.  Below is the article and the answer key to the worksheets.  Students who are absent will need to complete the worksheet when they return.  Please also watch the video link posted below.

Friday & Monday February 22, 25

Friday and today we worked through a lab that provided evidence that Earth's land masses might once have been together.  Following instructions, students pieced together a puzzle using continent shapes, fossil evidence and rock evidence.  Below is what we copied into our notebooks.
Students also found that India was an additional piece that matched better with with Africa and Antarctica than it did with Asia.

In steps 10-12 students compared their outline of the continents with these 4 sketches.  They were supposed to pick which picture their outlines best matched.  Students should notice that picture 2 best matched their outlines.
The continents were believed to be in one large mass 230 million years ago in a super continent called Pangea.

Lastly, students completed 2 analysis questions.

Question 1:  Describe what has happened to the land on the surface of the Earth over the past 425 million years.

Questions 3:  What types of evidence did the puzzle provide to suggest Earth's land masses were together?

Test tomorrow over Earth Layers, Convection, and Earth's magnetism!  Please study using the quizlet posted below.  Also use the information in your notes and on your Earth Layer's worksheet.  Be sure to know your diagram and prepare an answer to the question "How does density drive convection currents in the asthenosphere?"  Scroll through this week's previous blogs for more resources!

Today we completed a formative on Layers of the Earth.  The answer key is posted below.  We also learned about how the inner and outer core helps generate Earth's magnetic field.  Please put the white writing in the notes into your notebook.  There is also a video link and a link to a review quizlet posted below.

Earth Layers Quizlet Link

Today we reviewed what density is and how it drives convection currents in the asthensphere.  We also completed the notes on Layers of the Earth.  All notes are on the previous blog. 
Please take a look at today's bellwork.  You will see a short answer question similar to this on the test.

Thursday February 14

Today we are completing a foldable for notes on Layers of the Earth.  Below is a picture of how the foldable should look.  The notes are written behind each layer on the foldable.

On the next clean page in the notebook we will complete a Density Lab.  The lab is shown at the bottom of the slides.  Students should be able to relate how density drives convection currents in the Mantle.

Tuesday February 12

Please put your name in the upper right hand corner of your worksheet (on the diagram side).  Use the picture below to fill out your diagram. Then, go to the website link below.  As you click on each layer you should be able to fill in the blanks on the back of the worksheet.
If you finish before the end of the period, please go to the Earth Layers quizlet link on yesterday's blog.

Today we introduced the Virtual work that is due Tuesday February 12.  The assignment is on Google Classroom.

We also took time today to complete a data table that introduces students to different geologic time periods.  Students have the worksheet.  The information that we filled in during class is shown below.  Students need to take the time to fill in Data Table 2.

Monday February 4

Geologic Timeline Scavenger Hunt due Tomorrow!

Today we took time to look at different fossils, learn the geologic period in which they were thought to have formed, and the beginning and ending time of that period.  To answer these questions we used a geologic timeline.  Below is a picture of the worksheet and the geologic timeline.
