Check out this Using Songs and Rhythm Information Sheet to see how and why I use songs and rhythm in the classroom.

I pull up the Layers of the Earth song lyrics, so the children can sing along with the song.

It is a common thread that is woven into the NGSS, science practices and in the cross-cutting concepts. How could you model each of the layers of the Earth?

Some have speculated that the innermost part of the core is enriched in gold, platinum and other siderophile elements.[30].

Composition: iron and nickel.

By making this simple model they will expand their thinking about how objects can be described in terms of their parts.

Having the children explain their idea to a partner helps them clarify their thinking.

After you have made your model, I would like you to explain it to your turn and talk partner. [23][24] The laser studies create plasma,[25] and the results are suggestive that constraining inner core conditions will depend on whether the inner core is a solid or is a plasma with the density of a solid.

Troposphere.

I am asking the children these questions to help them think like a scientists. ACTIVITY Assess and apply your learning STATIC Side-by-side comparison of composition vs. mechanical properties • Whole Earth • Near surface.

Obtaining, evaluating, and communicating information. I had explained each of the layers of the Earth to the children. If not, voice that idea. August 21, 2018. The syrup acts as glue for the M&M. In the context of rocks, what does the word "stress" refer to? Also, this serves as a quick evaluation of what they have learned.

Henry Cavendish in his torsion balance experiment of 1798 found a value of 5.45 g/cm3, within 1% of the modern value.

by Mihai Andrei. You should be explaining how each of the parts are represented. They then hold the tab at the top down and lift the top layer up, which creates a fold. [17] Because the average density of surface material is only around 3.0 g/cm3, we must conclude that denser materials exist within Earth's core. In this lesson the children will be using diagrams and making a physical replica, which are two different types of models. When they are done coloring, they need to cut out all of the pieces.

In the previous lesson, the children learned about models and how they have parts that work together to represent the whole. Thus the children need some background on the layers to help them understand how these events happen. It is catchy, and educational. They will be making this physical model of Earth with an Oreo cookie and an M&M.

Understanding models is an extremely important concept. Was making the model helpful?

Do you think this representation was accurate?

[31][32] Beginning as early as 1940, scientists, including Francis Birch, built geophysics upon the premise that Earth is like ordinary chondrites, the most common type of meteorite observed impacting Earth. We end the session by singing the Earth layers song. Knowing this song, "Throw your hands up for the layers of the Earth--inner core, outer core, mantle and crust" will help the children when they are making their models and also when they are explaining it to a partner. Hopefully someone will comment that we also need to represent the outer core. Media related to Structure of the Earth at Wikimedia Commons, Inner structure of planet Earth, consisting of several concentric spherical layers. Seismic measurements show that the core is divided into two parts, a "solid" inner core with a radius of ≈1,220 km[20] and a liquid outer core extending beyond it to a radius of ≈3,400 km. Some have argued that the inner core may be in the form of a single iron crystal. The video has a song on it about the layers of the Earth, and my children love singing. Watch this video clip of my class "getting into the groove" singing the Layers of the Earth song.

What is the difference between a layer based on composition vs. response to stress? {\displaystyle {\tfrac {9}{5}}} Temperature: 4,300 K (4,030°C) in the outer regions to 6,000 K (5,730°C) closest to the …

BetterLesson reimagines professional learning by personalizing support for educators to support student-centered learning.

Oreo cookies--1 per child (1 package has over 50 cookies), M&Ms--1 per child; a small bag will be enough for a classroom, chocolate syrup--1 small bottle --(You will have lots left over), small plate or napkin--1 per child (to put the Oreos on). Can you think of an antonym for the term homogenous? Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

It is so thin that it will not fit on the model itself and will have to be placed on the background paper. In order to do this, I again pull up the poster of the layers so they can use it for a reference when coloring. that of surface rock, concluding that the interior of the Earth must be metallic.

They will also begin to understand that systems in the natural world have parts that work together. The solid inner core is too hot to hold a permanent magnetic field (see Curie temperature) but probably acts to stabilize the magnetic field generated by the liquid outer core. They need to see that models are very helpful in understanding the parts of the Earth, especially since it is not tangible and I cannot bring it into my classroom. The Earth’s …

As a science practice and part of the NGSS, the children are expected to understand and develop models.

You are going to have a chance to make your own Earth model. Crust. Then I have the children elaborate on the ideas learned by making their own EDIBLE model, yum! [18]

Mechanically, it can be divided into lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. By the end of this unit, called Earth Changes, the children will have to understand how the movement of the crust and mantle creates changes, either quickly or slowly.

# earth layers diagram

[19] They also need to be thinking about how each of the parts were represented and what was chosen for the representation.

This ignores the less abundant enstatite chondrites, which formed under extremely limited available oxygen, leading to certain normally oxyphile elements existing either partially or wholly in the alloy portion that corresponds to the core of Earth.

The crust is the uppermost and thinnest layer of the Earth made up of mainly sial (silica and … Inner Core. But before we begin our modeling, I show this, .

The children first need to color the Earth and the layers (see earth sample cover and inner sample).

The inner core was discovered in 1936 by Inge Lehmann and is generally believed to be composed primarily of iron and some nickel.

[22] Other experimental studies show a discrepancy under high pressure: diamond anvil (static) studies at core pressures yield melting temperatures that are approximately 2000 K below those from shock laser (dynamic) studies. Then they glue the inner layer down in their science notebook or on a piece of paper.

The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically.

Earth's crust is what we walk on every day. When we are eating our models, we watch a short video of Ice Age and Scrat taking a journey to the center of the Earth.

So getting them to think how and why I used clay helps and if it was effective helps them see primary limitations of the model. Was the interior of the early Earth more or less homogenous than it is today? This is an area of active research. As they progress through the years, they will have to understand that models have their limitations. The average magnetic field in Earth's outer core is estimated to measure 25 Gauss (2.5 mT), 50 times stronger than the magnetic field at the surface.

Other possible motions of the core be oscillatory or chaotic. In this lesson, they get to make their very own simplistic model. Dynamo theory suggests that convection in the outer core, combined with the Coriolis effect, gives rise to Earth's magnetic field.

Since the children explored the idea of making models in the previous lesson, we are going to elaborate on that idea today. It is the thin (relatively) outermost layer that wraps …
