What you should do?- Design your own experiment. Come up with an observation that you can take through the entire experimental procedure. Complete the experimental design and turn in as a part of your lab report.-Write out what you would do for each part of the scientific method, be sure to to list all variables (independent, dependent, and control).Scientific MeasurementScientific measurements are almost always in metric system units. They are as follows:Meterstandard unit of lengthLiterstandard unit of volumeGramstandard unit of massPrefixes for unit values less than the standard unit are:Centi one hundredthMillione thousandthMicroone millionthNanoone billionthThus, a centimeter is1/100 of a meter and a millimeter is 1/1000 of a meter. The major advantage of this system is that conversions can be made from one unit to the other by multiplying by 10 (or multiples of 10) or by dividing by 10. For example, centimeters can be converted to milliliters by multiplying by 10 and milliliters to centimeter by dividing by 10.

As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
