(7th Grade) Crayon Rock Cycle Lab Conclusion


Look at all three “rock” samples. Use your simulated “rocks” to help you describe the following rock types:

1. What constitutes a sedimentary rock and processes must occur to produce a sedimentary rock?

2. What is a metamorphic rock and processes must occur to produce a metamorphic rock?

3. What is an igneous rock and what processes must occur to produce an igneous rock?

4. Explain the evidence of the original rocks (the different crayons) in the igneous, metamorphic, and sedimentary rocks that you made?

(7th Grade) The Rock Cycle Notes

Rocks are classified into three main groups. Igneous rocks are rocks that crystallize as molten rock (magma or lava), cools, and hardens. Sedimentary rocks are formed from cemented rock fragments, chemical precipitates, and organic remains. Metamorphic rocks are formed when other rocks are altered by heat and pressure.rockcycle

The rock cycle describes how rocks can be transformed from one type into another. For example, a sedimentary rock such as limestone can be transformed into the metamorphic rock marble if it is buried deep in Earth’s crust and subjected to high temperature and pressure. If an igneous rock such as granite is uplifted and exposed on Earth’s surface, the action of plants, rain, ice, and snow will break it up into sediments. The sediments will be smoothed and rounded as they are carried to the ocean, and eventually they may be deposited on a beach. Over time, the beach sand may be buried under other layers of sediment and cemented into sandstone.

Convection currents in Earth’s mantle provide the energy to keep the rock cycle moving. These convection currents cause the motion of tectonic plates. New crust is created in mid-ocean ridges and old crust is destroyed in subduction zones. Mountains are created along convergent and collisional plate boundaries. In these regions, rocks created deep below Earth’s surface are uplifted and exposed to the weathering forces of rain, sunlight, wind, ice, and plants. Over millions of years, these forces act to break down rocks into smaller particles,forming sediments and soil. The sediments are transported by rivers and streams to the ocean, where they are deposited in layers on the continental shelf. Over time, these layers are buried and harden into sedimentary rock.

Igneous Rocks

Igneous rocks are the ones that were superheated and originally liquid. They often start their lives below the crust and then get pumped out. There are two basic types of igneous rocks. There are the rocks that make it to the surface(extrusive) and the ones that are stuck in the crust just below the surface (intrusive). These igneous types have all hardened after being molten rock. Some examples of igneous rock are granite, all volcanic rock, basalt, and obsidian.

Metamorphic Rocks

This rock type is created by heat and/or pressure. Even though heat is involved, they didn’t start off as molten rock. You often find metamorphic rock near volcanoes and sources of super hot rock. The heat from the magma changes all of the rock around it. Heat/pressure has changed these rocks from one type into a new type. The result is a metamorphic rock. Some examples are marble, jade, slate, and gneiss. Because pressure and heat are involved, these rock types are usually found deep beneath the surface. They are also found near fault lines where plates push against each other and create enormous pressures. Over time, because of the movement of the crust, these metamorphic rocks are pushed to the surface where you can find them every day.

Sedimentary Rocks

The last of the big three rock types is probably the rarest… unless you live near the coast. Sedimentary rock types are created when sediment compresses. Here’s the setup… A river flows through a canyon and picks up a bunch of silt. That sediment and silt runs downstream and deposits where the river ends. It could be in a flood plain or a valley, but we’re using a coastline as an example. When that material gets to the beach, it sits there. Now if you watch this happen over millions of years, more and more sediment builds up and compacts. That compacted sediment eventually becomes a type of rock. Examples of sedimentary rock include sandstone, amber, anthracite, and limestone.

(8th Grade) Exploravision Update #3 – Project uploading info

Note: While the Toshiba Exploravision deadline HAS been extended for my students, I am not going to be at school Monday Feb. 8th due to the regional science fair.

 I will upload projects via email received by Sunday Night at 8:00 PM.
See information below on project file format.

Additionally, I will stay after school on THURSDAY and FRIDAY to upload projects. You will sign in as you enter my room after school.  You must have a plan for how you will get home. Please bring a note for how you are getting home or where you are to go after we finish. Here are the directions from the website:

  1. Please name your file the same as your Project ID #. For example, if your ID # is 275G, then your file should be named 275G.doc. Prior to uploading, make sure the Project ID # and Project Title are included on each page of your document.
  2. Max size upload is been set to 10MB for performance purposes. Please try to keep your file under 5MB for best performance. If page times out, please try again.

(8th Grade) Feb 1/2- Exploring Density


This week in Science class students are exploring the physical property of density.  We will participate in a number of virtual and hands on investigations where we explore how density is a ratio of mass to volume.

Today students had a final opportunity in class to complete the following assignments:

  •  A3K: Burning wood: Bad for the planet?
  • Fusion Lesson Reviews (pg. 309 and 327)

These assignments will be added to the gradebook by the end of this week.

I met with students in small groups and reviewed our  Life Science assessment. Students received their test back to help prepare for the Retest next class (Wed. Feb 3).

We also got started on our Virtual and Hands on explorations with density.


  • Review for Life Science Retest (as applicable) 

  • Group Science Project Investigations (exploravision/eCybermission)

(8th Grade) eCybermission Project updates

Those of you who are working on the eCybermission team project need to tell me the following so I can update your team account:

  • Project Topic (from the list of topics available)
  • Scientific Method vs. Engineering Method.

Once I have that information you will have access to your shared team mission folder.

Let me know if you have any questions!

(8th Grade) Jan 28th- Density Lab Gizmo/Fusion “Properties of Matter”

Today you have two assignments to complete:

  • http://www.explorelearning.com “Density Laboratory Gizmo” – Complete the Student Exploration guide AND Assessment questions.

  • Fusion Textbook – “Properties of Matter” pg. 312 -325.
    Read and answer questions in textbook – ALL the questions, NOT just the Lesson Review.


Toshiba Exploravision Project

Completed project submissions, including all Sample Web Pages, must be received at NSTA by 5:00 pm EST, February 1, 2016 – See more at: http://www.exploravision.org/avoiding-disqualification#sthash.XNg0cgHP.dpuf

I will upload projects on both Thursday, January 28 and Monday, February 1 after school. If you do not have me upload your project then it must be mailed and received on or before Feb. 1. Late projects do not receive full credit.

Each complete project must consist of:

Submission materials will not be returned. Please retain a copy for your records. You may photocopy any part of the submission materials. Unfortunately, due to the volume of submissions, it is impossible to give individual critiques to participants.

* If you are submitting projects online, the mail in entry form is not required.

**sample webpage forms may be downloaded from your coach dashboard when logged into your account on our website.
