During Monday’s lesson Year Six’s discussed variables which change within a fair test. We discussed how we could create a fair test, and investigated the effectiveness of how animals use different beaks when hunting for food. Children used different pieces of equipment to represent the beaks: sharp tweezers for the sharp beak of eagles; flat tweezers for the heavy and thick beaks used by cardinals; lollypop sticks for the flat beak bills used by ducks to scoop; and a chopstick to represent probing beak used, for example, by hummingbirds. We then used string, raisins and straws to represent worms, bugs and sticks. Children decided how they would make the test fair, what they would change, what they would measure and how they would make every other variable remain constant.
