Ice Sculptures

Flesch-Kincaid Reading Level = 5.1

In the Kalahari Desert of South Africa are some odd-looking rocks. The rocks are flat and polished, as if something very large and heavy has scraped across their surface.

Halfway across the world, in the southwest corner of Lake Erie, is Kelleys Island. The bedrock there is grooved. It looks as if something large and heavy has moved across the rock, gouging out these deep lines.

What caused these strange things? The flat, polished rocks of South Africa and the grooved rocks of Kelleys Island were left behind by giant moving walls of ice called glaciers.

Glaciers are made of ice. Ice is a solid. But glaciers are so large and heavy that they actually move like a liquid. You can think of glaciers as slow-moving rivers of ice.

Today glaciers can be found on very high mountains. Snow falling on high mountain slopes doesn’t melt. Instead the snow turns to ice and adds its own weight to the weight of ice already there. When the ice is heavy enough, the glacier begins to move down the mountain, spreading into the foothills and valleys below. As it moves, the glacier scrapes and shapes the mountain’s sides.

Like mountaintops, polar regions stay cold all year long. Glaciers grow there too. They press and grind the land below as they move. When a glacier reaches a coastline, pieces of ice can break off and form icebergs.

Today glaciers are found in only the world’s coldest places. But during ice ages, glaciers and ice sheets covered the land over much of Earth. Three hundred million years ago, the Kalahari Desert was covered by glaciers. That ice slowly moved. It scraped across the rock, leaving the flat, smooth rocks behind.

Starting around three million years ago, an ice sheet covered much of the midwestern United States. This ice sheet advanced and retreated many times. It retreated for the last time around fourteen thousand years ago. This ice sheet is responsible for the glacial grooves of Kelleys Island. As the glacier moved, it picked up heavy boulders and pushed them along. These boulders, some made of hard rock, scraped at the softer limestone of Kelleys Island, forming long channels. These channels are the glacial grooves of today. They are clear evidence of the wall of ice that once moved across the land.

Ice has shaped the world in surprising ways. The rugged coastline of Norway was once covered in ice. Today, fjords line the coast. Fjords are fingers of water that stretch inland along u-shaped valleys. Moving ice carved those valleys. The mountains of Europe and the Great Lakes of North America were also sculpted by ice. Glaciers formed giant lakes where none had been before and produced rich soil for growing crops. Even though the glaciers have retreated, we can see their sculptures all around us.


fjord – a deep valley filled with water

glacier – a large mass of ice that slowly moves

ice ages – times in Earth’s history when the world was extremely cold

icebergs – large pieces of ice that float in the sea

ice sheet – a mass of ice that covers more than 19,000 square miles of land

Notes for assembling the books:

You can put this book together a couple of different ways. You can print out the pages, cut them in half and then order the pages back to front. Fold the stack in half and then staple the spine of the book. Pairs of pages can then be stapled or glued along the right edge.

You can also assemble the book as a foldable book.

To assemble the book this way, print the four pages and align the document pages so that the following book page numbers are in the lower right-hand corner: front page, page 6, page 2, and page 4. (The cover page should be on top and page 4 on the bottom.) Set your copier to copy single pages into double pages and run the four document pages in the order specified. Cut along the dotted line in the center of the double-sided page, place the book pages in order, fold, and staple along the spine.

In the Articulate version, click on the small arrow at the top of each page for the narration. The large arrow at the right will take you to the next page.

In the Flash version, the play button (in the top right hand corner) will play an audio file of the text on that page, while the pawprint (bottom right hand corner) will turn to the next page. Please note that the audio files take a moment to load on each page. Once the file has been loaded, a play button will appear in the top right hand corner of the page. To minimize the delay on each page, you can open the file and read through the article first. Once each page’s audio has loaded, it remains loaded until you close the browser window. By preparing the article ahead of time, you can have students start at the beginning of the book and read without delays. If you don’t have Flash, you can download it for free from the Adobe web site.

Reading Strategy Templates

The article provides an opportunity for students to practice the comprehension strategy of visualization. The following template can be used in conjunction with “Ice Sculptures.” For more information on this strategy, please see “Visualizing to Understand Content Area Text.”

Visualizing Glaciers
This template can be printed and used in conjunction with the Feature Story, “Ice Sculptures.” As they read, students create images to represent the content and write a caption to accompany each image.

Literacy Set
Everything you need to teach the strategy of visualizing: a content knowledge article, template, and illustrated and electronic book copies of “Ice Sculptures” at all three grade bands.
