Babysitter Needed for my Children

Someone who could come up with, plan, and do science projects with them (twins) would be great. We homeschool and they love anything hands on. They learn better that way. We also have a pool and they love to swim, someone who could swim in the summer with them in the afternoons when I can't due to heat intolerance would be great. They love anything outdoors. They also have a wii and love to play it on days that are too hot to be outside. They love imagination play. They will be 10 in December.
