informative speeches on children

I need an informative speech topic and it has to deal with children somewhere between the age of 2 and 10. Any ideas would be very helpful. Thank you.

Here are a few ideas

- Detecting Asberger's syndrome in young children
- Colour blindness
- School dinners - should we be spending more than 37p ($0.74) on the ingredients?
- Dealing with disruptive children
- The school trip
- 7 things that you can build with Lego (this could be interactive)
- Barbie dolls
- The top selling toys of the year
- Shreck
- The making of Sleeping Beauty
- Teaching kids Powerpoint http://www.presentationmagazine.com/...teach_kids.htm
- Presenting to young audiences http://www.presentationmagazine.com/...n_children.htm
- Is home education a real option?

Does anyone else have any other ideas?
