SCIENCE: Owl Pellets, Atoms, Chain Reactions & Surface Tension

Here are some pictures of some of the Science experiments we have been doing this year...

 

DISSECTING OWL PELLETS:

We dissected an owl pellet at the library with other homeschoolers. Owls cannot digest the fur and bones of a rodent, so they cough it up into a pellet. JJ thought it was really cool to dig through a pellet and find the little rodent bones. I helped EL get through it, but she was not thrilled.

 CHAIN REACTIONS:

Getting ready to whisk egg whites to make meringue cookies

Whisking the egg whites whips air bubbles into the albumin,
producing a chain reaction.



The albumin traps the bubbles, making a foam.
When you bake it, the foam hardens into meringues.
  

 

SURFACE TENSION:

Pepper flakes sprinkled onto water float on the top
because of surface tension.



A drop of detergent breaks the surface tension
and pushes the pepper flakes away.
