Problem 2. Find a way to measure the size and mass of a cell, a virus, or a bacterium.

To solve the problems raised, use one of the following strategies:Strategy 1. Identify multiples and submultiples of the units of mass and length to express your results; doing this will help you shorten the writing of the numbers you will find.

Strategy 2. Remember that special instruments are used to measure very large and very small quantities, and include them in your poster. If you think it is convenient to use another strategy, write it in your notebook and share it with the community.
