Introduction
Grade 11 Biology students at Havergal College, a secondary school for girls in Ontario, Canada, have created a wide variety of treehouses on organisms such as watermelon snow, black mambas, clownfish, ostriches, pacific treefrogs and more! We highly recommend checking out these fun, creative and educational story, game, art and culture and investigation treehouses.

Investigations- Jellyfish, "Stinging Creatures"
-
- The class Scyphozoa can be found in the phylum of Cnidaria, the phylum of the “stinging” creatures, such as jellyfish. There are approximately 200 species that belong to the class Scyphozoa, and they are the most familiar of the gelatinous creatures of our world. These include, sea nettles, moon jellies and jellyfish. The jellyfish found in this class are dubbed "the true jellyfish". Many people associate the Portuguese Man-of-War and other well-known jellyfsh-like creatures with these Scyphozoans. However, in fact, the Portuguese Man-of-War and these other species are not "true" jellyfish. Yes, they have sac shaped bodies and long tentacles that sting painfully, but they are still structured differently than those organisms of Class Scyphozoa. And, hence, they are not "true" jellyfish.

By looking over this website you will find the answers to questions you never even thought to ask about an organism as seemingly boring as moss. Next time you come across that bit of green fuzz you will not leave unimpressed.

- Sponges are the simplest form of multi-cellular animals. They are very diverse and come in a large variety of colours, shapes and structural complexities. They range in heights of 1-200cm and in diameters of 1-150cm. They have partially differentiated tissues, and not true tissues. Sponges don’t have internal organs. They don’t have muscles, a nervous system, or a circulatory system. Their walls are lined with many small pores called ostia that allow water flow into the sponge.

- Although known for its bright pink-red colour, watermelon snow, scientifically known as Chlamydomonas nivalis, is actually a species of green algae. While most forms of green algae thrive in fresh water habitats, C. nivalis can be found within the snowfields of mountains and on top of glaciers; this is surprising as other species of green algae would not be able to survive in such a harsh, cold environment.
