You would think that humans make up more mass than ants do on this planet, but think again, and this time by performing calculations. Middle schoolers use scientific notation to compute and compare the estimated total mass of all humans...

Have you ever wondered how many ants make up an elephant? Inquisitive minds will be amazed as they use scientific notation to compute and compare the mass of an elephant to an ant. Have participants make guesses and see how close they...

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

Students investigate how to compare scientific and standard notation numbers. Exercises are provided to practice the skill.

In this activity, students develop models for a light year and compare numbers written in scientific notation and in standard notation.

This excellent math resource explains and defines the meaning of percent. Multiplying and dividing by a power of 10 is incorporated as a preview to understanding scientific notation.
