Many cool science experiments can easily be carried out at home. These experiments require a day to be completed and also need careful monitoring. If weather conditions interest you there are numerous science projects you can practice at home. Discovering the properties contained in rain is just one of these experiments.
An example of a meteorology or environmental science projects involves finding out what is contained in rainwater. Materials needed include a microscope, two containers, funnel, clear tape, a glass pie dish, and filter paper.
The first step of this experiment is obviously to gather some rain in a container. The container should be dry and clean and placed on open ground away from buildings and trees and left until it has collected sufficient rainwater to be examined.

The next step is to filter the rainwater. This can be achieved by placing a piece of filter paper in your funnel. The funnel should be attached slotted into a separate, clean, dry container where the newly filtered water will collect.
When this has been done you need to dry the filter so that the water evaporates. Turn the oven to 100 degrees Celsius and then place the filter paper on a baking sheet for 15 minutes. While you wait for the filter paper to dry, pour the newly filtered water into your pie dish.
To conclude the experiment when the water has evaporated from both your pie dish and filter paper you can discover what your filtered rain contains.
Place your filter paper under the microscope. Using a piece of the clear tape, attach it to the bottom of the pie dish once there is no more moisture. Examine the tape under the miscroscope and then ascertain which particles are present in your newly collected and filtered container of rainwater.
