what stuff are u guys using for ur  experiments?

hello everybody. what plants apart from celery are you using?
I haven't started testing yet am I the only one? : (
hi guys just wanted to know what you are using  for your ingredients for your recipe like

Info on Variables

Scientists use an experiment to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way.
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens.
The scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable.
For example, if you open a faucet (the independent variable), the quantity of water flowing (dependent variable) changes in response--you observe that the water flow increases. The number of dependent variables in an experiment varies, but there is often more than one.
Experiments also have controlled variables. Controlled variables are quantities that a scientist wants to remain constant, and he must observe them as carefully as the dependent variables. For example, if we want to measure how much water flow increases when we open a faucet, it is important to make sure that the water pressure (the controlled variable) is held constant. That's because both the water pressure and the opening of a faucet have an impact on how much water flows. If we change both of them at the same time, we can't be sure how much of the change in water flow is because of the faucet opening and how much because of the water pressure. In other words, it would not be a fair test. Most experiments have more than one controlled variable. Some people refer to controlled variables as "constant variables."

abbey told me to

hey guys just showing abbey sruff

whos started their testing

Do you have to do 3 samples of three tests

Variables

Hey guys,

Everyone participating in this group please comment and tell me what your variable will be doing.

I just want to know what everyone else is doing because I might change my one.

Thanks a lot,

Haris Moazzam.
Hey has anyone started their testing apart from me?
Invisible ink from a genius

Um I think

Variables I think 
Controlled and something else

Help ME!!!!!

What is that one about what we changed about it and what we kept the same? Please help me!!!

Some things about pesticide


Background information: Pesticides are used to kill off bad plants and weeds. Farmers use them a lot and they can actually be very useful, but only if you use them properly. If the pesticides are in contact with other plants that farmers want to grow, the those plants will die as well. Pesticides are dangerous and could affect humans, and humans are strongly advised not to drink it. it could sting if in contact with skin, especially cuts. Pesticides are used very commonly, even some pesticides are used on vegetables, but those are normally minor pesticides. If you want to grow organic stuff, don’t use pesticides and control the weeds yourself. It will be a hard job but it makes better vegetables.

Good start guys - lots of good information and ideas! Nice pictures Kenny.

some pictures :)

information on pesticides

What they are talking about is the pesticide causing a mutation in a plant cell. This would be similar to being exposed to a chemical that increases your chance of getting cancer. 

A pesticide sprayed on a plant will not cause all the cells in a plant to have their DNA change or to be mutated. It may increase the chance that a plant will have mutated cells, but for the most part pesticides will not harm the plant. The bigger concern is your personal exposure to the pesticide or eating any vegetables or fruit from a plant sprayed with pesticide.

Some information on plants


Plants, also called green plants (Viridiplantae in Latin), are living organisms of the kingdom Plantae including such multicellular groups as flowering plants,conifersferns and mosses, as well as, depending on definition, the green algae, but not red or brown seaweeds like kelp, nor fungi or bacteria.
Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained inchloroplasts, which gives them their green color. Some plants are parasitic and may not produce normal amounts of chlorophyll or photosynthesize. Plants are also characterized by sexual reproductionmodular and indeterminate growth, and an alternation of generations, although asexual reproduction is common, and some plants bloom only once while others bear only one bloom.
Precise numbers are difficult to determine, but as of 2010, there are thought to be 300–315 thousand species of plants, of which the great majority, some 260–290 thousand, are seed plants (see the table below).[2] Green plants provide most of the world's molecular oxygen and are the basis of most of the earth's ecologies, especially on land. Plants described as grainsfruits and vegetables form mankind's basic foodstuffs, and have been domesticated for millennia. Plants serve as ornaments and, until recently and in great variety, they have served as the source of most of medicines and drugs. Their scientific study is known as botany.

What do I do first the aim or the hypothesis.

Thanks
Ben

Help I don't know what to do
