I was as dubious as you, Bethannie, and am further still having just done a quick quiz (fully marked, no cheating etc) with the mixed Y5/6 group I'm working with today (so 9, 10 and 11 year olds) To give context, our kids are broadly average when they leave here although are well below when they arrive. The catchment is mixed local authority and privately owned, largely working class but with pockets of deprivation. Not privileged by any means. We also have a high proportion non-British children and families. And...out of a group of 24 kids: 1. All 24 knew an egg comes from a chicken or hen - 100% 2. 23 out of 24 knew that bacon comes from pigs - 95.8% (the one who didn't has English as an additional language so there may be language and cultural reasons for not knowing). 3. 21 out of 24 children knew what bread is made from. Wheat or grain was the most common answer but I accepted corn (from a Brazilian girl) and was also lenient and accepted flour. 87.5%. So - I declare this survey largely bollocks.
