Scientific Measurement

Kids, here is a self-test you can take to test your understanding of scientific measurements, significant figures, and scientific notation.

Take The Pretest & Lots More!!!

Here are some other helpful links:

• Practice counting sig. figs. - interactive exercise

• Quiz on significant figures
  Tutorials on "arithmetic with units" and "uncertainty in measurement"
  - see also answers to FAQs on scientific notation, sig.figs., and specific gravity; skim over course notes.

• SI Units - National Institute of Standards and Technology (NIST)

• Why should we submit to using standardized units? I dare you to browse through this list of units of measure: http://ts.nist.gov/ts/htdocs/230/235/appxc/appxc.htm
  

Five more sites you may what to try if you need help during the year are:

	A Tutorial for High School Chemistry
	ChemOnLine
	CHEMTUTOR
	Chemistry Resources
