Letting Biology Teach Itself

For young students, seeing really is believing, and the best way to teach biology is by putting away the textbook and showing kids the magic of life. The GeoSpace Easy-Hatch Fish Hatchery is a great tool for teaching the details of aquatic reproduction and ecology. The fish eggs come dehydrated and grow into brightly colored tropical fish in a matter of days. The set costs $25 and includes the bowl, eggs, a magnifying glass and a supply of shrimp eggs for food.
