Science 6.E.2.1 Earth’s Structure WEDNESDAY JANUARY 6 TH, 2016

Warm Up  Bring your notebook, pencil, and agenda to your desk  Complete Wednesday’s warm up now  If you did not finish notes from yesterday, grab your chromebook now and complete this  YOU ARE QUIET, WORKING WHEN THE BELL RINGS

Supplies needed for our clay models….  If you are able, please bring in all purpose flour and salt by Thursday  We need these items to make our play dough Earth models on Friday

Rap sheet  You will receive a sheet of paper with the lyrics to the Rap song “Layers of the Earth”  Follow along to the video and fill in the sheets blank phrases.  If anyone wants to they can rap along!  Keep the sheet as a study guide

Pay close attention to the rap video tch?v=HOd7PRJMkkQ

Let’s Review now with a pop quiz  You are able to use your notes to complete this 10 question pop quiz  Clear off your desk except for your notebook and a pencil  You will receive 2 folders to sit up around your desk  You will have 15 minutes to complete this quiz

Trade and Grade  I will collect the papers now  I will pass out the papers again so you can grade a fellow classmates  Remember this pop quiz does not really test anyone’s knowledge, just if you used your time wisely yesterday and copied all the notes  Good Luck!

 Have scientists ever seen the inside of the Earth?  If not, how do scientists know what it is like?

Mystery Boxes!  You are going to examine 1 of 4 boxes and make an inference as to what is inside each box  Here’s the twist though…..  You cannot open the box  You can however lift the box, shake the box, smell the box ….basically use your senses other than sight to make conclusions and an inference as to what’s inside!  You will work with everyone in your row to complete this activity  Someone will be a recorder: the recorder will write the group’s inference on a note card to share with the class

Mystery boxes  We will review each group’s inferences later….  Box 1  Box 2.  Box 3.  Box 4

Let’s investigate  How scientists know what is inside the Earth even when they cannot see inside!?  Every Changing Earth Textbooks:  You will read the passages from read pg 71-73

Questions to answer in your notebook – raise your hand when you are done  1. What is the main tool scientists use to study the Earth’s interior?  2. What are seismic waves? How do seismic waves travel inside the Earth?  3. Why do scientists study chunks of mantle rock they collect after volcanic eruptions?  4. What is one final way scientists infer what is inside the Earth aside from studying rock samples and seismic waves?

Let’s create a “slice” of earth  You will be given a slice of Earth  You will be labelling, coloring, and adding details to each layer

Let’s create a “slice” of earth  You will label the 4 layers now

Let’s create a “slice” of earth  You will lightly color the layers now Oceanic Crust-blue Continental Crust - brown Mantle-Yellow Outer Core-Orange Inner Core-Red

Facts about the Layers  You will now move around the hallway to gather your facts about each layer  You only have 5 minutes to record this information  Remember you are recording the following:  Composition (what it is made of)  Thickness (in miles)

Facts about the Layers Continental Crust Composition: granite rock and loose materials Thickness: 25 Miles deep

Facts about the Layers Oceanic Crust Composition: basalt rock Thickness: 5 Miles deep

Facts about the Layers Mantle Composition: super heated rock material Thickness: 1,800 Miles deep  Draw a convection current in this layer as well

Facts about the Layers Outer Core Composition: super heated magma; liquid layer of iron and nickel Thickness: 1,400 Miles deep This layer is responsible for the Earth’s magnetic field

Facts about the Layers Inner Core Composition: solid layer of iron and nickel Thickness: 780 Miles deep Nearly as hot as the surface of the sun!

Let’s create….  Now we will put several “slices of the Earth” together to make a sphere detailing the interior of the Earth

Ed Helper  You will receive this worksheet for homework  Once your slice of Earth is complete you may start working on this worksheet

Another Music Video  Mr. Lee “Layers of the Earth” Write one phrase you remember  Earth's Layers Earth's Layers  RiHRI_Z2Kgs RiHRI_Z2Kgs
