Day+07

=Day 7 - The Seafloor=

**Introduction**
Ocean basins, which are low areas of Earth that are filled with water, have many different features and contain minerals that can be mined.

**Materials**
- Earth Science textbook - mobile notebook lab or classroom computer lab - SMARTBoard - PowerPoint - Earth Science Chapter 18-19 packet

**Step 01:** Teacher led PowerPoint review of textbook reading

 * In your science notebook jot down some thoughts you might have as I review the material you read for today.

**Step 02:** Create a VoiceThread
> If others have done all the features **ONLY THEN** should you do the same feature as someone else.

 * Please watch the VoiceThread for your group before doing anything else.
 * **DO NOT** choose the same feature someone else did in your group **UNLESS** all the features have been used.
 * After watching the VoiceThread, choose **ONE** of the features from the list below that are found in the ocean basin.
 * Create a VoiceThread
 * Label and describe the feature as you are creating the VoiceThread.
 * __**Ocean Basin Features**__
 * Continental Shelf
 * Continental Slope
 * Seamount
 * Oceanic Trench
 * Volcanic Island
 * Abyssal Plain
 * Mid-ocean Ridge || media type="custom" key="14123976"

Step 03: Create a profile of the Atlantic Ocean basin
In order to gain a greater understanding of the features of the Atlantic Ocean Basin, you will __**work with your classmates**__ to create a profile of the Atlantic Ocean Basin along 39⁰21'.00 N starting at Atlantic City, NJ and ending at Peniche, Portugal. Use Google Earth and the Ruler tool to assist you.

To make sure you are fairly accurate, zoom in so you're eye altitude is within a few kilometers of the surface of the ocean. If you need to set Google Earth's unit of measurement to metric, select **Tools >>> Options >>> Units of Measurement** then select **Meters, Kilometers**, click **Apply** then **OK**.

Each of you must choose **ONE** distance from Atlantic City, New Jersey, eastward into the Atlantic Ocean from the list of distances in the GoogleDocs Spreadsheet shared with you. Measure then record your depth in the Spreadsheet using negative integers. As you do that, the Atlantic Ocean Basin profile will be __**automatically drawn for you**__ in the line graph in the image below. Refresh this page to see any changes after you enter your data in the Spreadsheet.  ROOM 222 Students use this link --> [|Room 222 - Mapping the Ocean Floor using GoogleDocs Spreadsheet]. ROOM 223 Students use this link -->  [|Room 223 - Mapping the Ocean Floor using GoogleDocs Spreadsheet].

Step 04: Display on a map the locations of minerals found in the ocean basins.

 * **Each of you will contribute to __one__ map** showing mineral resources on the ocean floor.
 * Use your textbook pp. 545-547, or other sources online and the GoogleDocs DrawingI've shared with you to accomplish this.
 * Choose a mineral and draw or place an object on the map indicating location the mineral can be found.
 * Add the name of the mineral to the map key if needed.
 * Use this link to access the Drawing
 * Use the following rubric to guide your activity.
 * ~  ||~ Ocean Floor Mineral Map Rubric ||~   ||
 * 2 || 1 || 0 ||
 * Mineral identified and appropriately displayed on the map || Mineral misidentified or misplaced on the map || Mineral misidentified and misplaced on the map ||
 * Mineral added to the map key using the appropriate color || Mineral added to the map key with the wrong color || Mineral not added to the map key ||

** Step 05: ** Read for tomorrow's class

 * Read Section 19.2 pp. 549-556
 * Fill out the guided reading sheet.

__**Steps 2 and 5 MUST** be completed by tomorrow's class.__
