A Question of Scale
In standard scientific notation, numerical quantities are written
as
$$
a\times 10^b
$$
where $b$ is an integer and $a$ is a decimal number less than $2$
and not less than $1$.
Construct your best estimates of the lengths of the quantities on
the slips of paper and rank them according to their exponent $b$
when written in scientific notation.
Use units of metres, so that, for example, $1.0 \times 10^3$ would
correspond to $1$km.
The challenge is to correctly rank
all of the quantities.
Note that there is one slip of
paper per exponent, so you might be able to use detective work to
rank unfamiliar quantities.
