Question

Hey!

I need to do a science model and I need ideas. Its due this fri!!

I need to make one of these:

1) The Water Cycle

2) Rural Water Treatment and Disposal

3) Urban Water Treatment And Disposal

4) Different types of Erosion

If any of y'all have an idea on any of the following plz answer.. I will sooooooooo pick best answer.

Answer 1

The first link is one idea for a water cycle model. It is a bit corny but it would be fairly easy to make and should look good.

The second link is another idea for a model. You could take a wire coat hanger and bend it in to a circle and then make cutouts like this water cycle has and glue them to the ring in the proper places.

The third link has a picture of a rural waste water treatment plant.

The fourth link has a picture of an urban waste water treatment plant.

The fifth link has a flow diagram of a typical waste water treatment plant. Both rural and urban treatment processes are similar, the most important difference is in the size of the plant.

The last link talks about erosion. You should mention all of these types: Gravity erosion, Water erosion, Shoreline erosion, Ice erosion, and Wind erosion.

I hope that helps.
