Plant Biology
Objectives/Goals My goal was to observe which would grow better, seeds germinated in the light or in the dark. Methods/Materials I used four different seeds. Arugula, Sweet Pea, Cantaloupe a…
Plant Biology
Objectives/Goals To experimentally determine if the ripening of a banana is effected by the environment. Methods/Materials First I put the bananas in three different bags. Bag #1 had an unri…
Plant Biology
Objectives/Goals There are two main different ways to grow plants, but which is best for growth efficiency, soil-grown or hydroponics? It is hypothesized that hydroponics is the best method…
Plant Biology
Objectives/Goals In a climate like the Desert, non-native plants to the area are hard to grow outside without constant watch. Gardeners in such a climate could grow these non-native plants i…
Plant Biology
Objectives/Goals The purpose of this experiment is to determine how the wavelength of light affects photosynthesis. My independent variable is the wavelength of light in nanometers (nms). My…
Plant Biology
Objectives/Goals What kind of ingredients can be used to keep cut flowers fresh? By experimenting with the use of 7up, bleach sugar and the combination of an aspirin tablet & a penny (all co…
Plant Biology
Objectives/Goals For my science fair experiment I wanted to find out how will Coca-Cola affect the growth of plants. I hypothesized that the plants would grow taller and grow more leaves. Me…
Plant Biology
Objectives/Goals I'm trying to see which organic acid: humic acid or fulvic acid, can speed up the growth of green mung beans. I think humic acid would be the best since it is composed of th…
Plant Biology
Objectives/Goals One component of Global Warming is the influence of green house gasses such as CO2. In order to better understand the potential effect on flora, I evaluated the impact of el…
Plant Biology
Objectives/Goals To determine what influence various fertilizers have on the growth rate of a green onion plant. This project focused on the study of mitosis and the study of different chemi…
Plant Biology
Objectives/Goals My objective was to test the application of positive and negative words on the growth of 2 types of plants. Methods/Materials I used two types of systems for delivering the…
Plant Biology
Objectives/Goals The project's objective was to determine if the light and gravitational changes found in each of the four moon's cycle would have an affect on seed germination and plant gro…
Plant Biology
Objectives/Goals The objective of the project is to study the occurrence of native and introduced species in various aged redwood forests in Humboldt County. The forests observed have been l…
Plant Biology
Objectives/Goals Can the geographic location of local live oak trees be found by the varying degree of travel of chlorphyll in paper chromatography strips, from sample trees from those areas…
Plant Biology
Objectives/Goals How much oxygen do plants small enough to be in an office give off under different ammounts of light? Methods/Materials Procedure- 1.Time candle light inside air tight box,…
Plant Biology
Objectives/Goals This experiment looked to discover the effects of higher levels of UV radiation on the health of plants. To determine the health of the plant, I calculated relative amounts…
Plant Biology
Objectives/Goals In our world today, due to global warming from burning fossil fuels and the rapid decrease in the supply of fossil fuels, it is necessary that we begin to turn to renewable…
Plant Biology
Objectives/Goals In my experiment, I wanted to test how much of a difference plant fertilizers have on the growth and health of bulb plants. Methods/Materials Materials: Narcissus bulbs, soi…
Plant Biology
Objectives/Goals The objective of my project was to determine how the variables of salt water, vegetable oil, vinegar, and detergent soap affect the height of the Japanese Boxwood plants. Re…
Plant Biology
Objectives/Goals To find out what different concentrations of salt do to plant growth. Methods/Materials Materials: Salt water; 50 large plastic cups; Potting soil; Water; Seeds (peas); A na…
Plant Biology
Objectives/Goals My project was to see how the salinity of water affects the germination of radish seeds. I think that the higher the salinity, the harder it will be for the plants to extrac…
Plant Biology
Objectives/Goals The olive fruit fly, (Bactrocera oleae,) could wipe out the entire olive oil industry in California. Because its maggot feeds on the inner pulp of the olive, it allows bacte…
Plant Biology
Objectives/Goals My objective was to learn if watering with Liquid Plant Food will help plants grow faster than using other solutions. The purpose of this project was to find out whether dif…
Plant Biology
Objectives/Goals My objective was to determine how far plants should be grown from sunflowers in order for them to be safe from the sunflowers' allelopathic toxins. Methods/Materials I plant…
Plant Biology
Objectives/Goals To find the percent variation of water storage among different succulent species. Methods/Materials Forty-five grams of eight succulent species which are: Red Apple Ice Plan…
Plant Biology
Objectives/Goals My objective was to find out if tea is beneficial to plant growth and health. Would the type of tea used for watering the plant effect plant growth? Additionally, would usin…
Plant Biology
Objectives/Goals This experiment tested the effect of common types of runoff water on corn plant growth. Runoff is an important issue in our communities. There are several types of runoff wa…
Plant Biology
Objectives/Goals My objective in this project is to try to find plants that can sustain alternative means of irrigation other than fresh water. My goal was to find an element that would coun…
Plant Biology
Objectives/Goals Seed germination is the process in which a shoot and a root emerge from a seed thereby ending its dormant stage. Gibberellic Acid is a naturally occuring plant hormone that…
