Animal Record-Holders

Science · Animals of the World · conceptual

Know some of the world's animal record-holders — the blue whale is the largest animal ever, the cheetah is the fastest land animal, the bee hummingbird is the smallest bird, the giraffe is the tallest — and compare their sizes to familiar objects

Sign in to track this

What mastery looks like

  • Names at least 4 animal record-holders with their record (fastest, biggest, tallest, smallest, etc.)
  • Compares an animal's size or ability to a familiar reference
  • Shows enthusiasm for superlative animal facts

Check your understanding

If you ask Animal Record-Holders which animal is the fastest or the biggest in the world, can they name some record-holders like the cheetah or blue whale and compare their size to something familiar, like 'a blue whale is as long as three buses'?
