Our study on invertebrates starts
when I hit a cockroach. I called my
little one, showed her and told that it
does not have a backbone and it’s an invertebrate.
But my little one felt sorry for
the cockroach and asked me why I hit it.
“It would be paining” she added.
“No, it won’t. It lacks a nervous
system and invertebrates cannot feel the pain.”
I had a lizard skeleton which I preserved
a long ago for our vertebrate unit. I
also had a fish skeleton. I brought it and we had a closer look using our magnifier.
I set our vertebrate tray with a paper
human skeleton, a plastic Dinosaur skeleton and the skeletons of fish and lizard.
Watch this wonderful video by Arvind Gupta to make
a simple paper skeleton.
For a sorting practice, I gave her
a handful of toys from our miniature unit.
She went inside, took the entire miniature unit and started sorting it.
But, soon she started playing with her whale and shark.
