To make a working model on land pollution, you must first consider what branch of this type of pollution you wish to represent. If you're a competent model maker, you might want to try something more challenging - such as an investigation into the effects of increased mechanization on the environment - whereas less experienced constrictors should probably stick with more simplistic models to avoid confusion and difficulty when trying to convey the scientific principles across to whoever views their model. The easiest type of land pollution to reproduce in the form of a model is probably soil pollution - using soil taken from your garden or a field - to show the effects of waste disposal, excessive fertilizer use and acid rain on this form of matter.

You could use a deep container to make your working model in and then section it off into four quarters. In one quarter you could put a sample of healthy soil, in another a sample of littered soil, in the third a sample of soil that's been damaged by excessive fertilizer use and in the final section a sample that's been affected by acidic rainfall. You could then carry out chemical analysis tests on each of the samples to compare the nutrient content in each. Using laminated card stuck onto cocktail sausage sticks, you could write down the composition of each sample and then stick it into the correct quarter to indicate how various types of pollution impact upon soil quality.

If this idea isn't something that appeals to you, how about trying to replicate one or more of the following types of land pollution in your model: Waste disposal problems, modern mining issues, eutrophication caused by excessive fertilizer use, a lack of waste recycling, etc.
