Fears are growing that kids are losing touch with the natural world after a survey found loads of you don't know what bluebells or frogs look like!
About 700 children, aged 9 to 11, were asked to identify pictures of popular wild species, like blue tits and oak trees, but only half of them could.
And only two out of three of the children asked could identify a frog.
Experts are worried that if you don't know more about the natural world you won't grow up wanting to look after it.

Famous wildlife expert Sir David Attenborough said: "The wild world is becoming so remote to children that they miss out - and an interest in the natural world doesn't grow as it should.
"Nobody is going protect the natural world unless they understand it."
The BBC Wildlife magazine, which carried out the survey, also found that playing in the countryside was kids' least popular way of spending their spare time.
But it's not all bad news... Most of the children HAD built dens or explored rockpools and almost all of them could identify wild animals like robins and badgers.
