There is no conclusion. New technology is advancing everyday, solar charged gas, solar towers, thorium, controlled fission(eventually) and so on... why settle for an alternative when we still have oil, coal and natural gas to burn. It's cheaper.
How do you conduct and science experiment on snails to help the growing of a plant?
snails are detrimental to plants. aim your experiment at exterminating them. they like beer and will gather at a shallow dish of beer set out in the garden. you can collect them there. or you can make a bait ; one can of stale beer, one pound of brown sugar, and one teaspoon 50% sevin wettable powder. mix until pasty, smear on the underside of a board and elevate just above the soil. this also will take care of slugs. i raise butterflies, so make sure the board is just above the soil.
How can i test my model rockets aerodynamics?
An easy way to test the general airworthiness of a rocket design is to tie a string around the middle of the rocket so it hangs "balanced". Then swing the rocket around your head in a big circle (kinda like twirling a lasso). If it's aerodynamically stable, the "nose" should always remain pointed "forward" as it goes around in a big circle.
What is the effect of gravity in Melde's experiment?
Gravity affects the string by applying a force (dm).(g) on every particle of mass dm. Thereby, it produces a damping effect on the string.
Why was it important for Thomson to repeat his experiment?
Thomson did the experiment various times to observe if the particles behave the same way. How they did he determined they were the same kind later called electrons.
# A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation. # Something taken to be true for the purpose of argument or investigation; an assumption. # The antecedent of a conditional statement
What is Lee's disc experiment?
It is an experiment to determine the conductivity of poor conducting materials. See http://media.uws.ac.uk/~davison/labpage/leedisk/leedisk.html
In an experiment what is the constants?
In an experiment, the constants are the things that are the same (or don't change) for the control group and the experimental group. For example: You want to see what the difference is of washing your dishes in the washing machine for 20 minutes and washing them in the washing machine machine for 30 minutes is, a constant would be to use the same kind of soap. Basically make sure that everything is the same for both groups besides the independent variable, or you will have an unintended variable.
Does temperature affect the amount of substance dissolved in a saturated solution?
Yes temperature affects the amount of substance dissolved in a saturated solution.
Experiments with cohesion have found that?
cohesions are protected from cleavage at the centromere during meiosis I.
How can you decorate your science board if its on the Stroop effect?
If you were to decorate your board, here are some suggestions to make your stroop board look nice:
- Make the board colorful
- Put the picture of the stroop test sheet
- Put pictures of your colors
Sorry if i didnt make too many suggestions. I am doing a stroop science project too so this is what I did.
Is watertight the same as airtight?
"No... no it's really not.
Water tight is when water can't get in
Airt tight is when air can't get in
So I guess it's similar. But different." Not an illuminating answer... Given that water molecules might be larger than oxygen molecules, then a watertight vessel may still leak air but an airtight vessel wouldn't leak either.
So would a spaceship immersed in water leak? Maybe the seals are different for a vacuum but you'd think it wouldn't?
Scientists do tests more than once to reduce chance of errors called conducting a what?
It is called repeated trials.
How do you keep a can of hot water hot for 40min?
use insulation to keep the water hot for 40 minutes
What is the specific rotation of limonene?
The specific rotation is +123 and -123 degrees for the (+) and (-) enantiomers respectively
What is the main difference between conclusion and results?
A result is what happend because of something but a conclusion is the total ending as in what happed in the end
What is the best science fair projects?
Anything but a volcano, they're too cliche.
(Improvement Begins Here)
That's technically true, they are quite cliche. But the best science fair project depends on what you think will set a good impression on you, and your friends helping you, and what you basically think can be added or improved from you. It's your project, so you decide what you do with it.
spearmint is some times used for toothpast and can even be used for eating
The responding variable is displayed on what axis?
By convention, the variable that is changed (the independent variable) is displayed along the horizontal or x-axis. The variable that is measured (the dependent variable) is plotted along the vertical or y-axis.
A responding variable is a dependent variable and would go along the y axis
Does the experiment work as well if you add the dry yeast without mixing it with water?
EH...... what the heck
The independent variable is what you are changing to get the results. In this experiment, the different types of cheeses are the independent variables. The dependent variable is your result. Therefore the dependent variable is what cheese grew mold faster.
The independent variable would be the amount of time you put the cheese out for and the dependant would be the amount of mold growing at the end of each time.
