I have a homework assignment on scientific notation. I am drawing a blank on an example except light years.

number of atoms in the Earth. Earth's mass is roughly 6E24 kilos. Number of atoms in Earth must be about 3.6E51. Pretty large (I think).
Or take our Milky Way. Its mass is estimated at 1E12 solar masses. This is 3.3E17 Earth masses. If you multiply by the above you'd get something like 1E69 atoms in the Milky Way.
There are an estimated 100 billion galaxies in the visible universe. That would give you about 1E80 atoms in the universe.
Small? Gravitational constant is 6.67E-11. Mass of a bacterium is about 1E-14 kilos. Gravitational force between two bacteriums 1 meter away from each other is (6.67E-11)(1E-14)(1E-14) = 6.67E-39 Newtons. Quite small.
Replace bacterium with electron (mass 9.11E-31), you get a gravitational force of just 5.54E-71 Newtons between two electrons 1 meter away from each other.
Now put the electrons at opposite sides of obervable universe, that's 150bn light years away from each other. Which is about 1.4E27 meters away. The gravitational force between the two would be about 2.73E-125 Newton. Quite small!
Hope this helps

The number of Sand Grains on the Beach = large Number 1 * 10^200 (?). The weight of an electron 0.0009*10-27 kg

the hairs on your head.
Small number (integer):
people at your dinner table
the number of your fingers
minutes to heat water in a microwave
Small number (fraction):
pounds of dirt on a seemingly clean window

An ampere of current is 6.02 x 10^18 electrons.
6,020,000,000,000,000,000. 6 quintillion!
Atoms are measured in angstroms. 10^-10 meters across. 0.0000000001
A googol is 100^100. a googol plex is 100^100^100.
Look to probability and nanotech!

How many cells are in your body = big number
What is the mass of one of those cells = small number
