“OCELLS, VIDA ANIMAL PER A NENS”

Avui hem vist aquest vídeo extret de la web edu365.cat. Ens hem aturat varis cops per  a respondre a preguntes tals com:

-How many species of birds are there?   -What other animals have wings?   -All the birds can fly?   -What are the functions of feathers?   -Who else, appart from birds, incubate eggs?   -What are the characteristics of birds?   -How can you distingish a reptile from a bird’s egg?   -How many days does a hen incubate the eggs?   -If they have no teeth, how can they smash the food?
