My science

Hi, Zack here on Tuesday I did some work on my science. What did we do for science we had to draw an eyeball with labels, and definitions. We also saw some objects that were opaque translucent and transparent, opaque means no light can go through, say when you shine a torch up to cardboard nothing goes through. translucent means it lets light through easy. and transparent means lets a little light through.

here is my work!

This is my the eyeball I drew.

  





here are my definitions

Irie: In humans and most mammals and birds, the iris plural irides or irises.

A macula on the skin is a small flat spot while the macula in the eye is a small spot where vision is keenest in the retina
The fovea centralis is a small, central pit composed of closely packed cones in the eye.
