    Miriam,
            The age level you have might be a factor in what is an appropriate
    activity, but an instructional activity that might be helpful and is more
    sophisticated than the "oatmeal game" could go something like this...

            Give a group of students an amount of coins (like 100 pennies) to
    represent the energy accummulated by the green plant producers from
    sunlight. Then have an exchange between individual students from group #1 &
    students from group #2 who would represent the 1st level consumers. The
    exchange would be a percentage (like 50%) of the coins held by individuals
    in group #1. The comment would be that part of the original cache of coins
    were used up by the life processes of the group #1 individuals, so are not
    available to be passed on. Then engineer a similar exchange between
    individuals from group # 2 (1st level consumers) and individuals in a group
    #3 (2nd level consumers). Using the same percentage of transfer (50%) at
    each exchange for the same reason as before, group #3 should now be at 25%
    of the original coins (1 x 1/2 x 1/2 =.25). If this makes sense to
    students, note that the "rule of thumb" for energy transfer is actually
    about 10% per level. Have the students go through the comparison of a sun
    to corn plant to human food chain compared to a sun to corn to pig to human
    food chain in terms of human energy needs. By comparing the "wealth" in
    coins at each level, this would also give an excellent example of why there
    is a food/energy pyramid with the "lower levels" having more energy
    resources and would help explain why there are many mice and few owls in an
    ecosystem.
