    __Nelson Rural School__: Keltie, Jacob and Jake __Purpose__: Does erosion really effect wildlife habitats? __Hypothsis__: We predict that erosion will affect wildlife habitats because it can destroy trees, banks (habitats on river banks), holes in the ground, pollute water etc. __Procedure: Materials:__ - Cardboard box. - Sand (enough to fill 3/4 of the box) - Water (1 liter) - Plastic Trees / Bushes - Garbage Bag - A book or something else about an inch high.

Step 1: Line the box with a garbage bag (to pervent leaking) Step 2: Fill the box 3/4 full with sand, add plastic trees / bushes / paper nests around the end of the box to simulate the look of a real river bank. Step 3: Put something, about 2 inches high under the end of the box to put it on a slant. Step 4: Trickle about 900 ml of water on the sand, and watch the effect it has.

after looking at a few websites we learned that Erosion affects the environment in a number of ways, such as the falling of trees, the flooding of forests, destruction from wind erosion, and a number of others. Erosion is the action of wind, water and ice that dislodges, dissolves or removes surface material. When material is removed from one location, it is inevitably placed somewhere else, this is called deposition. Both erosion and deposition are natural processes. But when human activities alter, serious damage can occur. We also learned that erosion really effects habbitats it puts dirt in the water and makes in harder for the fish to breath.

__Analysis__:

When we observed the experiment, after our second time pouring water down the box the trees got knocked over. The sand and trees pooled in the bottom of the box.

Conclusion: Our hypothesis was correct. Erosion really effects wildlife habitats. when we poured the water down the box it took some rocks down with it and at the end where the trees were, got knocked over and everything was left at the bottom.
