The Wolves and the Rivers

Wolves were shot out of Yellowstone by 1926. Fourteen were brought back in 1995. With no wolves, elk had grazed the valleys freely for seventy years. Young willow and aspen were eaten as soon as they grew. The wolves killed some elk. More importantly, they changed where elk would stand still. Open valley floors became dangerous, so the elk stopped lingering there. Willow and aspen grew back along the rivers. Beavers, which need willow, returned. Their dams made ponds. Roots held the banks. The rivers narrowed, deepened and moved less. Some researchers describe this as wolves changing the shape of rivers, though others argue the effect has been overstated.

  1. 1. Which trees grew back along the rivers?
  2. 2. When were wolves brought back to Yellowstone?
  3. 3. What overall structure does this text use?
  4. 4. The author reports a disagreement. What is it, and how is it presented?
2.Read the text, then answer the questions.

What a Coral Reef Is

A coral reef looks like rock and is built by animals. A coral polyp is a soft creature the size of a pinhead. It draws calcium from the sea water and builds a hard cup around itself. Millions of polyps, cup upon cup, become a reef. Inside each polyp live tiny algae. The algae make food from sunlight and pass most of it to the polyp. In exchange they get shelter and the polyp's waste. Neither could build a reef alone. When the water gets too warm, the polyps expel the algae. Without them the coral turns white and starves. That is what bleaching means. A reef takes centuries to build and can bleach in a single hot summer.

  1. 1. The text says neither organism could build a reef alone. What evidence supports that?
  2. 2. What overall structure does this text use?
  3. 3. How big is a coral polyp?
  4. 4. What happens when the water gets too warm?

Answer key — Reading a Grade 4 Fact Text

Set 2. Prints on its own sheet.

  1. 1.1. Willow and aspen. 2. 1995. 3. Cause and effect in a chain, from wolves to elk to trees to beavers to rivers. 4. Some researchers credit wolves with reshaping rivers; others say the effect is overstated — both are reported without choosing.
  2. 2.1. The algae make the food; the polyp makes the cup and gives them shelter. 2. It defines a reef, explains the polyp and algae partnership, then explains what bleaching breaks. 3. The size of a pinhead. 4. The polyps expel the algae, and the coral turns white and starves.
