Camera Obscura - Working Model Eye (Sexto) By Elena

Elena's students build working models of eyes (camera obscura) in class using shoe boxes and tracing paper. 

Then they went out on a sunny day and tested them on the patio.  The construction is relatively simple but what you see inside the box - the world projected upside-down is weird and fascinating.  You can tie this in to the nervous system and the brain because the information that the eye collects is upside-down and the brain corrects it for us.  We don't see the world upside-down, our brain is too clever and adaptable for that.  Safety warning - Don't look at the sun!

KUBB: plastic-free, wooden game.

Stone Age, Bronze Age… Plastic Age?

The one material named by nearly all sources  was plastic. Plastic “has redefined our material culture and the trush we leave behind”
Kubb is a good outdoor game from Sweden.  Also known as Viking Chess.

And the most important,  Kubb set is crafted from eco-friendly material.

CLIMATE CHANGE is really not the issue.

BASIC EDUCATION and our ATTITUDE is !

Thanks to AMIGOS DEL KUBB.
