ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

I would include procedures as tools, but in response to the rock question:
Assuming that dropping two rocks is a gravity experiment, let's start with
simple apparati: What are you going to use to measure the distance from the
dropping point to the earth and ensure that they are the same? What are you going
to use to measure the size and mass of the rocks? What are you going to use to
measure the time from the drop to the impact? Then the procedure: How many
times will you repeat the experiment until you are satisfied that the results
are valid? What different circumstances, say different heights, will you use in
your experiment?
