Stinky Corpse Flowers [PDF ebook] 

The huge corpse flower rarely blooms, sometimes once every ten years. When it does, it gives off a strong scent-the stink of a rotting corpse! The gross smell has a purpose, as readers of this fascinating volume will learn. It has everything to do with a main subject of the elementary science curriculum: pollination. Other science topics covered include plant life cycles, structures, and adaptations. Fact boxes add even more expert information, while full-color photographs offer an up-close look at a unique, high-interest plant.
