  • Iridescence: bright rainbow-like colors that can change depending on the angle you look at them or the angle light hits them.
  • Pressure: a force against an object. Like when you use your hand to push a door open.
  • Thrust: to push in one direction.

Flashcard facts and information about feathers

Biology Bits stories are a great way for you to learn about biology a little bit at a time. We’ve broken down information into pieces that are very tiny—bite-sized biology cards. Cutting out the cards will let you organize them however you want, or use them as flashcards while you read.

This set of bits will teach you about the many ways birds use one of their finest features: feathers. To learn more about the science behind feathers, visit Feather Biology.

Biology Bits stories are a great way for you to learn about biology a little bit at a time. We’ve broken down information into pieces that are very tiny—bite-sized biology cards. Cutting out the cards will let you organize them however you want, or use them as flashcards while you read and study different biology topics.

When you’re ready to move on, use the blank cards to write out what you learned. You can copy what was already written. If you are up to a challenge, you can  write it in your own words. Just remember, don’t bite off too much at once!
