All of the seeds were planted on the same day. c. Some of the plants are taller than others. d. They put different amounts of salt in the containers. e. One container has smaller plants because it has the most salt. f. This experiment is to determine how salt affects plant growth. g. The students are pleased with the way the experiment is turning out. Directions 1.

Give the letter of that sentence and tell what observations you think led the student to write that inference? 415

6 MID-SUMMATIVE EXAM 2 Date Many people have written about the Grand Canyon. Below are examples from two authors. I do not believe that a person can spend two weeks voyaging through the depths of the Grand Canyon and not be in some way altered by the experience. I have never seen a picture that has ever done it justice. Bob Ribokas, Grand Canyon Explorer Those who write about the Grand Canyon generally begin by saying that it is indescribable; then they undertake to describe it. Joseph Wood Krutch, Author of Grand Canyon: Today and All Its Yesterdays Directions: Write a short paragraph below telling why you think people write about the Grand Canyon in this way. What do you think they are trying to tell the reader? 416

7 MID-SUMMATIVE EXAM 3 Date Directions: Fill in the blank in each sentence with one of the words below. elevation layers rock column samples plateau formation river miles sedimentary correlation 1. Limestone is an example of a rock. 2. A is a large, nearly level area of land that has been uplifted or elevated above the surrounding area. 3. Flat deposits of rock that cover a large area are called. 4. Geologists draw a to show the sequence of rocks they see in a particular area. 5. is vertical distance measured above sea level. 6. Geologists take rock and draw where they came from when they study an area. 7. When geologists work to find a relationship or connection between rock layers from two or more locations, we say that they are making a rock. 8. A is a rock layer composed of more than one kind of rock; the kinds and sequence of the rocks can be recognized from one place to another. Directions: Look at the photograph of a landform called Mexican Hat on page 21 of the Earth History Resources book. 9. Sketch this landform on the back of this sheet. 10. Label which rocks you think might be limestone, sandstone, or shale on the left side of the diagram. 11. Label which rocks are softer and which are harder on the right side of the diagram. 12. Explain how you know from looking at the photo which rocks are harder than others. 417

8 MID-SUMMATIVE EXAM 4 Date Directions: Edit sentences 1 3. east For example: The Sun always rises in the west. 1. Sediments that settle in water form a curved, vertical layer. 2. Each new layer of sediments mixes in with earlier layers. 3.

Put a check next to each rock listed below that is a sedimentary rock. limestone granite obsidian sandstone pumice shale 5. Write a 1 next to the sediments listed below that are usually part of sandstone. Write a 2 next to the sediments listed below that are usually part of shale. pebbles sand silt clay cobbles boulders 6.

She places a few drops of dilute hydrochloric acid on the rock and observes fizzing. What inferences can she make about the origin of this rock? 2. These are the notes a geologist made about a sequence of rocks. Top layer: Middle layer: Bottom layer: Limestone (brownish gray, contains fossil corals) Shale (black, contains leaf fossils) Sandstone (light brown, crossbeds, fossils of reptile tracks) Describe the environment that can be inferred from these rocks from the time the sandstone formed to the present. 419

14 MID-SUMMATIVE EXAM 8 Bright Angel Trail Field Trip Take a virtual field trip down the Bright Angel Trail in the Grand Canyon. The Bright Angel Trail starts on the South Rim at Grand Canyon Village. It winds its way down to the Colorado River, ending near Phantom Ranch. Here s how to take this exam. Quickly read through all the directions before you begin. Important note: You will be graded on the notes you write and how well you verify your notes using the field guide. You will not be graded on the name you give to the rock layer. Click the Expeditions Desk. When you see the clipboard, move the arrow to the left of Bright Angel Trail. Click the X. You will see an image of the Bright Angel Trail and four mileage markers. Your task is to identify the rock layer at the four different markers. Click one of the mileage markers. A photo and some text come up on the screen. Read the text and write notes (words or phrases, not sentences) that will help you identify the rock layer. Click the magnifying-glass icon or the arrows. You will see close-up photos of the rocks and possibly some new text. Make notes. Click the other icons to get more information about the rock layer. When you have made all the notes you think you need, go to the field guide (at the top of the screen) and choose the rock layer that you think best fits the notes you have made. On the recording sheet, write the name of that rock layer in the of rock layer column. Click that rock layer in the field-trip guide. Make a check in the Field-guide verification column on your sheet, next to each note you are able to confirm using the field-guide text. Go back to the Bright Angel Trail image and use the pull-down menu below the mileage marker to choose the name of the rock layer that you think is the best answer. Choose a new mileage point and continue this process until you have named the four rock layers at the mileage markers. Check your answers. No fair checking your answers until you have named the four locations you ve been given! Page 1 of 2 424
