Evolutionary Beak Experiment


In Science, we finished the term by conducting our own experiment to determine whether the size and shape of a birds beak really makes a difference to the type of food that it eats. We have been learning to identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution, and the beaks of birds are clear to see. We used sweets to be the ‘prey’ and the children each were birds and have different types of beaks (tweezers, large tongs, tooth pick and straw). They had to see how much “prey / food” they can “eat” by transferring it from plate to plate – jelly worms, hundreds and thousands etc. Each beak had 20 seconds to collect as much food as possible.
