Helena and her friend collected 185 sand dollars… independently while spending hours out on the sea on boogie boards while their adults watched from a considerable distance and let them do science.
- We counted them
- We watched them
- We talked about the small area they got them from, so how many are there… millions?
- We looked them up when we got home
- We put them back -looking after living creatures
We are now talking mark and recapture and statistics…
Oh and rotational symmetry 😁
These are comments and questions and just stuff being read, we are not talking sit down while I impart some knowledge to you stuff…. I may just have to model some kind of nature study though as my interest has been piqued, but I don’t want to take over.. na I want to know!
