My 6-yr-old came home with an egg carton of sweetcorn seeds he'd planted at school. We put them on the windowsill and they've sprouted beautifully. But it's June, and although it's very mild now (in Waikato) we're expecting to get winter weather soon. He's very excited about these seedlings and would love to grow them to fruition - do you think I could grow them in a large pot as an indoor plant?

Corn needs to be planted in rows about 6-800mm apart. Seeds need to be planted about 150mm apart. Best to grow 2 or more rows together in a block for pollination. When the tassel and silks come out it takes about 5 days for pollination. Then about 21 days for cob to be ready to pick. Read up on the net.
If you can stand your pot near a sunny window, you might be able to keep the sweetcorn growing. Protect it from cold temperatures and make sure it has plenty of light -
