Plant Biology
Second Award
Objectives/Goals The purpose was to determine how treatment of seeds in water with direct electric current (DC) before planting and duration of treatment would affect their germination rate…
Plant Biology
Objectives/Goals The goal of my Radish Round-Up science project was two-fold: to see if fertilizer aided the growth of radish seeds; and to find out if organic compost or store-bought fertil…
Plant Biology
Objectives/Goals The objective of this study was to find whether older or younger redwood trees are more affected by temperature and precipitation. I believe younger trees will be more affec…
Plant Biology
Objectives/Goals The objective was to determine if Iron or Nitrogen Fixing Bacterium will cause the most growth of algae in slough, river, or ocean water. Methods/Materials I collected three…
Plant Biology
Honorable_mention Award
Objectives/Goals Angiosperms have obtained tightly regulated floral determinacy to ensure proper floral organ development. Within the floral meristem of Arabidopsis thaliana, two genes, AGAM…
Plant Biology
Objectives/Goals The objective is to test how the photosynthetic rate of four plants, fragaria, galvezia, heteromeles and salvia respond to increases in atmospheric CO2 levels. My hypothesis…
Plant Biology
Objectives/Goals The objective of my project was to identify how the rinse temperature affected the sprouting of Mung beans. If there was a relationship, I also wanted to find the best tempe…
Plant Biology
Objectives/Goals The objective of my project is to determine if nitrogen and nutrient infused ashes from vegetation will have a significant affect on the pH level of soil and the overall ger…
Plant Biology
Objectives/Goals Objectives:This experiment investigates the effect of different UV light machines on radish seed germination. Hypothesis:#If we expose radish seeds to the three UV light mac…
Plant Biology
Objectives/Goals To determine the effect of plant density on plant growth. Methods/Materials Compass or other sharp tool 12 plastic pots masking tape permanent marker potting soil, enough fo…
Plant Biology
Objectives/Goals The objective of my project was to determine whether the speed in which you rotate a seed affects the direction it will grow. I believe that the constantly spun seed will gr…
Plant Biology
Objectives/Goals The objective of this experiment was to determine whether different types of music -- blues, classical, hard rock, and country -- affect plant growth differently. My hypothe…
Plant Biology
Honorable_mention Award
Objectives/Goals I wanted to understand how the rate of photosynthesis in the aquatic plant Anacharis is affected by different light durations (on/off cycles). I believe that if the rate of…
Plant Biology
Third Award
Objectives/Goals The objective of my science project was to compare the growth characteristics of plasma-treated plant seeds. A plasma is an ionized gas that consists of ions (positive or ne…
Plant Biology
Second Award
Objectives/Goals While watering the yard, I noticed the leaves beneath an African Sumac tree foamed up whenever water hit them. This made me wonder about the leaves of that tree. I did some…
Plant Biology
Objectives/Goals My projec is about useing different soil to plant the flower.I have 12 plant, they are in 3 groups: normal soil, baked soil, and half half. They are in 4 different enviermen…
Plant Biology
First Award
Objectives/Goals The objective of this experiment is to determine if the mutation controlling triforine sensitivity in primitive romaine lettuce (PI491224) is in the same or similar location…
Plant Biology
Objectives/Goals The purpose of this experiment is to determine if plants watered with greywater will grow better than plants watered with tap water. Methods/Materials A total of sixteen pla…
Plant Biology
Objectives/Goals The objective of this experiment is to look at the various pigments in leaves to be able to determine which pigments are more prevalent as the leaves change colors. Methods/…
Plant Biology
Objectives/Goals This project was designed to show the amount of friction, produced by different grades of sandpaper that is needed, for a vine#s tendril to elongate and twine itself around…
Plant Biology
Objectives/Goals My project's goal was to determine if vitamins affected the growth of a plant. For this purpose, I used Vitamin B, C, and D and Tap Water. Methods/Materials Three bean seeds…
Plant Biology
Objectives/Goals Our objective was to determine which environmental factor most affects the water loss from a plant due to transpiration- Is it light or is it temperature? From summer to win…
Plant Biology
Objectives/Goals The purpose of this experiment was to determine if the temperature of water used for hydrating a cotton seed will have an affect on how fast the seed will germinate as compa…
