Why should you leave the Bunsen burner with the air hole closed?
Because if the air hole was wide open, the flame will be blue, which is going to be really hot so you have to leave it at a safety yellow flame which is when the air hole is closed when lit. It could be dangerous to leave a Bunsen burner on a blue flame.
this is confusing, explain more clearly, geez is dat too much to ask?
Which step of the scientific method do you perform after the you state the problem?
Form a hypothesis
What was the first scientific step used by Zadock Thompson research the mysterious skeleton?
The first scientific step used by Zadock Thompson in researching the mysterious skeleton was observation. Zadock observed a whale's skeleton.
What is the 'sample' in and experiment?
A group selected from a population for observation in a study.
That definition comes directly from the glossary in my research in education textbook. In other words, I think you want to define the people in the study.
What is a psychologists method for testing a theory?
A psychologist would use the scientific method to test a theory, just as any other scientist would.
What is the order of the science project?
problem statement
research/background info
hypothesis
materials
procedures
variables
data chart
results
abstract
application
A substantive theory may be constructed within the process of identifying differences and similarities of contextualized instances, and patterns, across and within case studies focused on a similar theme. The content of substantive theory is mainly descriptive, focused on the essence, or substance, of the numerous case instances in a parsimonious relational structure.
Because there is no way to know what effects the other key variables are having on outcome. So, there is no way to evaluate any one variable, or its effects on outcome.
it leads to conclusions that are not debatable and is too narrow a topic.
Real life examples of scientific notation?
i found this on the internet:
Scientific notation is needed any time you need to express a number that is very big or very small. Suppose for example you wanted to figure out how many drops of water were in a river 12 km long, 270 m wide, and 38 m deep (assuming one drop is one millilitre). It's much more compact and meaningful to write the answer as roughly 1.23x10 to the 14th power than it is to write 123120000000000.
What is the unit for a time squared vs distance squared graph?
There's no such thing as "the unit" for a graph. Each axis has a unit, and you've
stated both of them in your question: One axis is marked in units of (time)2, and
the other is marked in units of (distance)2 . We fail to comprehend the physical
significance or applicability of such a graph, but if it somehow suits your needs,
then knock yourself out. We note that the slope of the graph works out to units
of (speed)2 , so maybe it has something to do with kinetic energy perhaps ? ?
What is the difference between forming a hypothesis and testing a hypothesis?
forming a hypothesis is when you come up with an educated guess.. what you think it may be .
testing a hypothesis is when you're testing to see if someone else's guess is right.
What is the scientific attitude and The Scientific Method?
Scientists must have a skeptical attitude.
As well, all Experiments are conducted by The Scientific Method.
What are the seasons in the southern hemisphere?
They are "opposite" of the northern hemisphere. When it is summer in the north, it is winter in the southern hemisphere. Therefore fall in the northern would be spring in the southern, winter in the N would be summer in the S, spring in the N would be fall in the south.
Seasons in the Southern Hemisphere:
A structured procedure for collecting information to test a hypothesis is?
It is called an experiment.
expiriment
Acceleration can be defined as the rate at wich velocity?
Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating.
This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.
I don't know if this is true, but my old science teacher at high school told us all that 'a piece of the sun the size of your fingernail, a mile away from you, would still be able to kill you with the heat it gives off".
