How a Canal Lock Works

A canal cannot run uphill. Where the land rises, engineers build a lock: a chamber with a gate at each end. A boat going uphill enters the lock through the lower gate. The gate closes behind it. Sluices in the upper gate are opened. Water flows in from the higher stretch of canal, and the boat rises with it. No pump is needed, because the water comes down by gravity. When the water inside matches the level above, the upper gate can be opened and the boat moves on. Going downhill, everything runs the other way: the water is let out, and the boat sinks with it.

  1. 1. What is the main idea of this text, and which details support it?
  2. 2. The author says no pump is needed. What reason is given?
  3. 3. What are opened to let the water in?
  4. 4. What is a lock?

How a Windmill Grinds Flour

A windmill turns moving air into turning stone. The sails are set at a slight angle. Because of that angle, wind pushing on them cannot pass straight through, so it pushes them round instead. The sails turn a horizontal shaft. A large wooden gear on that shaft meshes with a smaller one on an upright shaft, which turns the millstones below. Because the smaller gear has fewer teeth, it spins faster than the sails do. Four turns of the sails can mean twenty turns of the stone. The grain falls between two stones. The top stone turns; the bottom one does not. The grain is crushed between them, and flour comes out at the edge.

  1. 1. What is the main idea of this text, and which details support it?
  2. 2. How are the sails set?
  3. 3. What is the author's purpose, and how do you know?
  4. 4. Where does the flour come out?

Answer key — Reading a Grade 3 Fact Text

Set 18. Prints on its own sheet.

  1. 1.1. A lock lifts a boat between two levels — supported by the gates, the sluices and gravity. 2. The water comes down from the higher stretch by gravity. 3. Sluices in the upper gate. 4. A chamber with a gate at each end, built where the land rises.
  2. 2.1. A windmill turns wind into grinding — supported by the angled sails, the gears and the millstones. 2. At a slight angle. 3. To explain the windmill mechanism — every paragraph gives a cause for the next thing that turns. 4. At the edge of the stones.
