Plant Biology
Objectives/Goals Determination of silicate's effects on drought tolerance and growth of Lactuca sativa var Longifolia and Lolium perenne. Methods/Materials Lactuca sativa var longifolia and…
Plant Biology
Objectives/Goals My experiment was conducted to test whether plants need all elements of photosynthesis to survive and if plants can be revived after being deprived of one element. The goal…
Plant Biology
Objectives/Goals This investigation assess the effect of magnetic fields on a model organism: garden cress (lepidium sativum). Methods/Materials Eight samples of garden cress seeds were grow…
Plant Biology
Objectives/Goals The objective of this study was to use aerial photography with a drone to measure cover crop canopy development to determine which planting arrangement (one versus three lin…
Plant Biology
Objectives/Goals Problem Statement: Is the use of an Algae Bio-reactor a more effective method then using Conventional Techniques when the variable being compared is Algal biomass? Methods/M…
Plant Biology
Objectives/Goals My objective was to test which type of grass has the largest amount of biomass by using their fresh and dry weight. I believed the Corn plant would have the largest amount o…
Plant Biology
Honorable_mention Award
Objectives/Goals The objective is to determine the effects of sugarcane derived biochar on the drought tolerance of Lycopersicon esculentum and Lactuca sativa variation longifolia. Methods/M…
Plant Biology
Second Award
Objectives/Goals Nitrogen Use Efficiency (NUE) is of major concern to growers, especially to those who farm in semi porous soils. Actinomycete bacterium is found in many types of soil, but m…
Plant Biology
Objectives/Goals The purpose of this experiment is to reduce the use of water on farms to help the farmers during the on going water crisis in California. Methods/Materials Materials: 1: 40…
Plant Biology
Honorable_mention Award
Objectives/Goals The purpose of my project was to find out if there was a difference in vitamin C levels when growing wheatgrass in aquaponics compared with a soil medium. Methods/Materials…
Plant Biology
Objectives/Goals The objective of the project was to find out if a plant needs to photosynthesize if they are given the materials produced in photosynthesis, or if they have the capability t…
Plant Biology
First Award
Objectives/Goals Rhizomania poses a major problem to sugar beet worldwide, as it not only causes physical harm to the roots but also reduces the quality of sugar yield by up to 95%. Rhizoman…
Plant Biology
Objectives/Goals To study dissolved oxygen levels in water studying if aquatic plants make more dissolved oxygen than the mechanical stage of a filter, or an aquarium with just water. The di…
Plant Biology
Objectives/Goals We want to see if fertilizers can help a plant live longer during drought and if it can live longer during drought, we want to find out why. Methods/Materials Pea plants, Ir…
Plant Biology
Fourth Award
Objectives/Goals The purpose of my science fair experiment was to determine if aged bovine manure loses its nutrient levels and effectiveness as a plant fertilizer over time. I investigated…
Plant Biology
Objectives/Goals It is a well known fact that the rate of photosynthesis is dependent on the type and intensity of the light source. My goal was to determine the best source of artificial li…
Plant Biology
Objectives/Goals The objective of this project is to find the effect of wind speed on seed dispersal using dandelions and fan to mimic wind. I believe that the higher the wind speed, the fur…
Plant Biology
Objectives/Goals In my research, I have found that nutrient pollution is one of the most prominent problems in America. Excess nitrogen and phosphorus can lead to eutrophication and algal bl…
Plant Biology
Objectives/Goals The purpose of the project was to determine the effect of the duration of electric field on tomato plant growth. It has been established through research that the presence o…
Plant Biology
Objectives/Goals I tried to germinate a mixture of two different types of grass seeds in a container with tap water and germinate a mixture of two different types of grass seeds in a contain…
Plant Biology
Objectives/Goals To determine the most suitable germination and growth conditions for fava bean plants. Methods/Materials Planted fava bean seeds in different soils, lighting conditions, and…
Plant Biology
Objectives/Goals Our objective was to determine how different fruit-based compost solutions affect the growth of a radish plant. We hypothesized that the Honeydew and Cantaloupe (Melon) comp…
Plant Biology
Objectives/Goals My objective was to see if vegetable seeds would sprout if planted at depths other than the depth recommended on the package. I also wanted to see if seeds planted on the su…
Plant Biology
Objectives/Goals I wanted to test two types of growing methods. I used hydroponic systems and planting pots because they are commonly used. Methods/Materials Hydroponic system(raft), 2 gallo…
