Plant a Conker!

I was in the park with my three year old daughter. I found a conker on the floor. "Look," I said. "What's that?" she replied.

I explained, it's a seed, grows into a tree, you can play with it, it's spikey, but brown and shiny inside. "What?" she replied!

So, we're going to plant it...

So, right now, it's about 'Conker Season'. Grab one. Plant it. Share it's journey with this class. And, your next... Then, plant it in the school grounds. 

Talk about how it grows and remember where it came from and what it will grow into.

In fact, as the year goes on, plant the odd seasonal item and have it there in class as an ongoing experiment that can be referred to.
