How do you make conclusions in science fair projects?
You see the results of your experiment, and determine whether your hypothesis was true or false. Then, you write a summary of what you have determined from your experiment.
Sand and dirt which gets hotter?
Sand tends to get hotter than dirt when exposed to direct sunlight due to its lower specific heat capacity, which means it heats up quicker. Sand also has lower thermal conductivity, meaning it retains heat for longer periods compared to dirt. This is why sand at the beach can feel much hotter on a sunny day than the soil in your garden.
What are the results in a science fair project?
Your results are what happened. lets say you where doing a project where you where growing plants in different lights, and the one in the red light grew better, then you say something like, "my results where that the plant in the red light grew more than the one in the plant in the green light" ok Good Luck!!!!!

What is Conclusion for a science fair project?
It links back to the aim and you answer your question, based on the results you got.

What do clamps attach to in science?
it happens because it helps to keep the beaker stable with no shaking
Making soaps, neutralize acids, making batteries and fuel cell.
Who are the major emerging producers of Biomass energy?
Biomass energy comes from a number of different sources. The main source of biomass is essentially the paper-manufacturing industry as the pulping liquor from the processes used to make paper contribute largely to the growing amount of biomass.
In terms of the energy sources themselves, it would be best to refer to Wikipedia's article on biomass: http://en.wikipedia.org/wiki/Biomass#Biomass_sources. The section on Biomass Sources should provide all the information you need.
Why must scientist control variables in their experiments?
An experiment is a simulation of complete or part of a real scenario in a controlled environment. We come to know of various outcomes of an experiment based on the values/degree of the variables in different quantity/quality. Unless the variables are controlled, experiment can go out of hand and sometimes become a real disaster.
What do you do for a purpose on a science fair project?
Purpose on a science fair is basically what was the purpose that you chose to do the certain project in the first place or it could mean the purpose of the experiment.
Control
False
Why an experiment must have control?
An experiment must have a control to show what would happen if no factors were changed.
What is the number one science fair project?
Anything that involves the great American pastime of blowing stuff up.
