Why build a microscope? The following is a guide on how to build a stereoscopic microscope. This guide allows you to assemble, at a relatively low cost, an instrument that is useful for observing natural objects such as insects, plants, minerals, fossils and flowers.

The purpose of this experiment was to see what materials work the best in a sandbag for preventing a flood. Fine and coarse gravel, plant soil, and mulch are not usually put in sandbags to stop floods. Most people do not have a lot of sand that they can put in sandbags. That's why I'm doing this experiment, to see if fine and coarse gravel, soil, or mulch can have the same effect as sand.

This science fair project was conducted to find out how acid rain affects the growth of sunflower plants. The science fair project was carried out by watering the plants with water of different pH levels.

Global warming occurs when greenhouse gases in the planet’s atmosphere trap and retain heat, altering the earth’s climate. Plants are affected by higher greenhouse gas levels, even though they consume carbon dioxide and sunlight to make energy. This science project encourages students to compare the growth of a plant under natural conditions with a plant that has been exposed to extra carbon
Examine ways for the biological control, of a foreign plant, with its natural enemy without harming the native plants of North America. To determine if any stage in the beetle, Galerucella calmariensis and Galerwcella pusilla life cycle will feed only on purple loosestrife, Lathrum salicaria, or if it will feed on agricultural crops in North America.
Difficulty: Elementary school
This science fair project was done to evaluate the rate of decomposition of bio-degradable plastic in the natural environment. Biodegradable spoons are supposed to decompose with time, but exactly how soon does this process take place? The experiment involved using disposable spoons made from corn starch, wheat and plastic. These spoons were planted in soil.

Biodiversity hotspots are regions of the Earth with a high concentration of species. Plants are often important components of biological communities because they are at the base of the food web and provide living structures for other organisms. Species richness, or the number of species in an area, is one measure of biodiversity. In this science project, you are going to test the hypothesis
Is wind good for plants, or can then they survive without it? It is well known that plants need the proper amount of sunlight and water to grow, but what about wind? Do plants need wind to grow? How does wind effect plants? This experiment will provide insight to how wind affects the health of plants.
The purpose of this experiment was to determine how organic material affects the water absorbency of soil. The information gained from this experiment will aid gardeners by determining which organic material will benefit their plants the most.
Difficulty: Middle school
The purpose of this experiment was to determine how different deicers affect the survival of radishes. The information gained from this experiment could be used by farmers and gardeners to help select, when needed, the deicer least harmful to their plants.
