What are rocks and minerals?
- Rocks are made of tiny particles called grains
- The appearance of these rocks depends on the nature of these grains and the materials they are made of
Minerals:
Building blocks of rocks which are pure, naturally occurring solid metals.
You can have rocks made of 1 mineral (ex. limestone) or rocks made of 2 or more minerals (granite).
Of the materials found in the Earth's crust, the most abundant are:
- Calcite
- Quartz
- Feldspar
- Mica
- Hornblende
Identifying Minerals
Activity - Cooking Rocks(http://www.elementaryshenanigans.com/2013/04/the-rock-buffet.html)
1) In groups of 5-6, melt 2 Tbsp of butter in pan on low heat.
2) Once melted, stir in 1.5 cups cups of marshmallows until thoroughly cooked.
3) Turn off heat and stir in 2.5 cups of rice krispies and extra 'minerals'.
4) Transfer to buttered pan.
5) Cover with wax paper and press down.
6) Cool for 20 minutes.
Closer - Write 1 Kahoot question from what we learned today.
A Geologist's Mystery (pg. 358)
Geologist: A geologist is a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes that shape it.
Activity - Mineral Identification (http://www.mineralogy4kids.org/mineral-identification)
Igneous Rock
Igneous rock forms when hot magma
or lava cools and solidifies.
Earth’s surface
when extremely high
pressure and heat cause the original rock,
or
parent rock, to change form.
Rock Type Song
Starter - Trashketball
Is it possible for any of these rocks to be transformed into a different form?
Activity - The rock cycle game
Erosion: The process by which the surface of the earth is worn away by the action of water, glaciers, wind, or waves.
Deposition: Process of materials being moved and placed in another area by wind, water or glacial melting.
Mechanical Weathering
Rock is broken apart by physical forces, either water or wind.
Chemical Weathering
When oxygen and water mixes with various minerals in rocks and produces a different mineral.
Biological Weathering
Wearing away due to living things
Activity - Rocks that Fizz Lab
Extension - Weathering Games

- Explain a type of weathering
- What is erosion
- How is erosion and weathering different
- What causes changes in rock
Crust: Covers the surface of the earth and is the section we live on.
Mantle: Found under the crust. It is made of rock material.
The upper mantle is solid, and together with the crust forms the
lithosphere. The lower mantle is partly melted and has the consistency
of taffy. Rock material in the mantle can flow very slowly.
Outer Core: The outer core is composed of iron and nickel. The temperature
here is over 5500°C. It is so hot, the iron and nickel are liquid.
Inner Core: The intense pressure of all the layers forces the inner core into a
solid ball. The inner core has a temperature over 6000°C.
Layers of the Earth
- Create a model earth with it's FOUR layers. Below are some of the materials you may use!
1. Lego Model
2. Modelling Clay
3. Foam Ball and Color
4.Construction Paper
Closer - Candy Model
- Using an Oreo, an M & M and a drop of chocolate syrup, recreate the layers of the Earth's crust.
Starter - Trashketball
"Has planet earth always looked like this?"
Activity - Piecing the world together...
1- Place your landmasses into this formation.
2- What do you notice about these land masses?
3- Do you think you could make one large landmass?
4- What possibilities did you come up with and how?
5- How would they have gotten from your landmass to their current place?
6- ARE LANDMASSES STILL MOVING?...
- In 1910 a German scientist Alfred Wegener noticed that the shapes of the continents seemed to fit together.
- He developed a theory that at one time the continents had been joined together forming a single land mass called "PANGEA" (all lands).
- Since the time of Pangea, over time, the continents have drifted apart known today as "Continental Drift".
Closer - Pangea Flip Book (http://www.layers-of-learning.com/wp-content/uploads/2010/02/Pangea-Flip-Book1.pdf)
How do the continents move?...
The theory of Plate Tectonics states that the earth's crust is divided into 7 sections and floats on the mantle.
Plates that are moving together are called CONVERGING plates and results in mountain range formation.
Plates that move in opposite direction are called DIVERGING plates that result in volcano formation.
Activity - Design a Plate Techtonics Lab!
- Materials
- Procedure
- Observations Table
- Questions
Starter - You are at home and you hear an earthquake is coming in 1 hour, how would you prepare for it?
The crust of the earth is technically broken into separate plates that have been shifting around slowly since the Earth cooled billions of years ago.
Tectonic plates shift around Earth at an extremely slow rate, about 1-2 inches a year (think about the speed your fingernails grow).
Earthquake
- Trembling/vibrations in the ground caused by the sudden release of energy slowly building up in the Earth's crust.
- Tectonic plates push on one another causing pressure to build up. This causes the rock to first change in shape and then break, this break is called the FAULT.
Activity - Design your own Seismograph!
- Using basic household items, design and build your own seismographic that records P and S Waves!
Closer - How are earthquakes caused?
Class #2 - Earthquakes
Starter - Demonstrating P and S waves
Focus: Where the earthquake is originating.
Epicenter: Point on the surface directly above the epicenter.
Fault: Area where the rock breaks.
Activity - Earthquake building challenge!
Today, you will be acting as engineers.You will be creating model buildings and conduct an experiment to test how well your structure stand up under the stress of an earthquake. This is similar to the type of test some civil engineers would do!
Since earth has a limited number of resources, each group of FOUR will get the following...
- 30 toothpicks
- 30 marshmallows
Challenge
Using the materials you have been given, create a free standing structure which will survive a jello earthquake. You will get TWO attempts to create your strongest structure possible!
