Ideas for Science Fair projects please?!?!?!?

Question

well im a sophmore in highschool and im in Ag Biology...and my teacher is makeing us do a Science fair project....and i need some good ideas...something not expensive but really interesting....i have nooo clue what to do...but it has to be something Ag related like Animals, plants....ect...any ideas please? or where i can look?

Answer 1

Involving animals? You can make a Maze for mice...Density of certain liquids, see how plants grow in natural light and in artificial light, Explain Thigmotropism by utilizing the Mimosa (touch-me-not Plant), The effects of certain chemicals on plant growth, (i.e. Nitrogen, etc.) How spinach was contaminated, how about what causes a fruit to ripen, when it is on the tree, outside on the table or in the refrigerator.

Answer 2

PLEASE READ!! I WON 1st PLACE IN COUNTY TWICE AND WENT TO THE CALIFORNIA STATE SCIENCE FAIR ONCE!!! I KNOW IT' LONG, BUT IT'S GOOD! :)

By the way, "Ag" I thought meant agriculture. So plants are good. Avoid doing the cliche projects with carnations changing colors from taking in colored water.

***The BEST ones haven't been done before! Or demonstrate scientific principles:

I thought it might be interesting to do one with plants in different environments, such as the following experiments.
I numbered each experiment, which I came up with myself:

1. Plants photosynthize due to the green pigment chlorophyll. Leaves look green because all other wavelengths of light are absorbed by the chlorophyll, providing energy need to make fructose (plant sugar).

To test this you'd take several plants of the same type and age (about) and isolate them from each other, using large cardboard boxes or other. Then you'd take lights and place them under the cardboard boxes and put the plants inside. By having each plant only recieve a certain color of light (and therefore a certain wavelength), you caould prove that the plants grown in red, yellow or blue lights flowered (or grew more flowers), or grew taller than the plants grown in green light. You'd have to water each plant the same ammount and leave the light on the same time. Record heights, flowers, or other observations.

2. Another good one would involve the plant hormone auxin, which causes the cells in shade to grow larger, therefore bending plant stems toward the lighter sunnier side.

You could do this by letting a plant sit on a windowsill with a relatively narrow ammount of light mainly reaching one side of it. Without moving it for a week or so, measure the angle of the stem. Or mark the shadowed side of the stem, to see if the mark moved up as it grew toward the light. Then you could turn the pot around 180 degrees and repeat and record results.

Answer 3

Test the effects of music on plants
Get 2 of the same types of plants and grow them both normally but let one listen to classical music and let the other listen to something newer

Answer 4

simple. get same type of plants and put them in a close environment, like a bottle, and put cigars inside, and see how the amount of CO2 might affect the plant. whether too much is bad, or the plant can take it.

Answer 5

Water purification systems. 1. Solid rock formations filtering the water or 2. Sandy soil filtering the water to be more pure 3. Modern technology, like a faucet filtration system Which method works best for our time?
