Lunch Box Police

This is a ClipMark that was made from an article highlighted by one of our UK Twitter EDTech colleagues. I thought it was worth sharing here on my teaching blog.

Our question was, "Where will the social controls end?"

Teachers could police lunch boxes
Lunch boxes
Head teachers' leaders fear they could be forced to snoop in children's lunch boxes under plans to tackle obesity.


New guidelines require head teachers to draw up healthy lunch box policies on what makes a nutritional packed lunch.

Head of the ASCL teaching union John Dunford said policing the contents of pupils' lunch boxes was a step too far.

Wormy, yet Cool Pictures

While this is an excellent article, I am discouraged that the writers refer to "AIR" and not "NITROGEN" because many people will think they are talking about oxygen.
This is fantastic research and very cool pictures.

Clams Convert Air into Food
Trait no longer the domain only of plants

Now scientists at Ocean Genome Legacy in Ipswich, Mass., and their colleagues at Harvard Medical School have shown that animals, too, can convert air into food. The National Science Foundation (NSF) funded their research.

The animals are marine clams called shipworms.
these clams use bacterial symbionts living inside a special organ in their gills to convert dissolved air [which is about 80 percent nitrogen] into the protein they need."

The discovery reveals a new way for animals to feed and suggests that other animals in the sea and elsewhere may be able to survive with only air as a source of protein.
