Kelp Forests: Gardens Under the Waves
Not all forests grow on land. Along some cold coasts, tall brown plants called kelp grow up from the sea floor and make a forest under the water. Kelp is not a tree. It is a kind of seaweed, and it has no real roots, flowers, or seeds. A small part at the bottom, called a holdfast, grips the rocks so the kelp does not float away.
The long stalks of kelp reach up toward the sunlight near the surface. Like land plants, kelp uses sunlight to make its own food. Little gas-filled bubbles on the leaves help the stalks stand up in the water. Some kinds of kelp grow very fast, adding many inches in a single day.
A kelp forest is a busy neighborhood. Small fish hide among the leaves, where it is harder for bigger fish to find them. Sea otters sometimes wrap themselves in kelp so they stay in one place while they rest. Sea urchins crawl along the bottom and nibble on kelp. If there are too many urchins, they can eat a whole forest. That is one reason kelp forests need hungry animals that keep the urchins in check.

One passage, three levels
The same topic and facts written three ways, so a mixed class can read and talk about one text. Each group’s sheet shows only a shape; the key says which is which.

Some forests grow in the sea. Along cold coasts, tall brown plants called kelp grow up from the sea floor. Kelp is not a tree. It is a kind of seaweed. It has no flowers or seeds. At the bottom is a holdfast. It grips the rocks so the kelp stays put.
The long stalks reach up toward the sun. Kelp uses sunlight to make its own food. Little bubbles of gas on the leaves help the stalks stand up. Some kelp grows fast. It can add many inches in one day.
A kelp forest is a busy place. Small fish hide in the leaves. Bigger fish cannot find them as easily. Sea otters sometimes wrap in kelp so they stay in one spot to rest. Sea urchins crawl on the bottom and nibble kelp. Too many urchins can eat a whole forest. So the forest needs animals that keep the urchins in check.

Not every forest grows on dry land. Along certain cold coastlines, towering brown plants known as kelp rise from the sea floor and form an underwater forest. Although it looks like a tree, kelp is actually a kind of seaweed, and it has no true roots, flowers, or seeds. Instead, a small structure at its base, called a holdfast, clamps onto the rocks so that the kelp is not carried away by the moving water.
The long stalks stretch toward the sunlight near the surface. Like plants on land, kelp relies on sunlight to produce its own food. Tiny gas-filled bubbles along the leaves keep the stalks floating upright in the water. Some varieties grow remarkably fast, adding many inches in a single day.
A kelp forest is a bustling neighborhood. Small fish shelter among the leaves, where larger fish have a harder time finding them. Sea otters sometimes wrap themselves in kelp so that they remain in one place while they rest. Sea urchins creep along the bottom and nibble on the kelp, and if there are too many of them, they can devour an entire forest. For this reason, kelp forests depend on hungry animals that keep the urchins in check.
