I just purchased a unit study about gardening for 5.00 at Amanda Bennett's website. She has two studies available for older kids - Flight and Gardens - as well as about 5 of her download and go units, all for 5.00 each. This couldn't of come at a better time, we are starting a gardening unit tomorrow for our science. You need to act fast if you are interested, the sale ends on Feb. 21st. Visit www.unitstudy.com to check it out.
