- What affect does the brightness of light have on the growth rate of a plant?
- Effects of different types of fertilizers on plant growth
- Which way is up? - Tropism and Auxin
- What happens when you grow sweet potatoes next to other plants? - Allelopathy
- How do different conditions affect the speed at which fruit and vegetables ripen?
- The effects of light on seedling germination
- How do different treatments change how fast seeds sprout?
- How does soil pH affect the pH of water that touches the soil?

Ecology and the Environment
Ecology is the scientific study of the interactions among organisms and their environment, and combines both biology and Earth science. Some of the various topics include the study of ecosystems, biodiversity, the effects of pollution and acid rain, and many more.
- Chemical contamination of lakes and streams
- Acid Rain
- Measuring pH
- Determining the pH of Common Substances
- Making a Natural pH Indicator
- Measuring Soil pH
- Soil Buffering
- Observing the Influence of Acid Rain on Plant Growth
- Observing Buffers in Lakes, Ponds, and Streams
- Looking at Acid's Effects on Metals
Nutrition
Nutrition science is the study of food and health, the materials or nourishment necessary to sustain life, and the organism's response to diet.
- Do different varieties of the same fruit have the same level of vitamin C?
- Are there different amounts of iron in different breakfast cereals?
- Are all apples equally sweet?
Microbiology
Microbiology is the study of microscopic organisms. Here are a few Microbiology Projects that examine the effects of mold & bacteria on plant growth.
- What happens to the way plants grow if there are no microorganisms in the soil?
- Are different plants affected in different ways by specific microorganisms?
