Looks good. A couple of thoughts:

1) I see you've left the 'cutting tools' category up to the parents. That makes sense given the situation.

However, you can steer them with a few inexpensive suggestions that are better than a razor blade and aren't weapons in any sense:

- cheap paramedic shears (under $2): no-one can really object to these, since you can take them in your airline carry-on luggage; good for cutting bark, fabric, grass/cattails, small twigs, twine, first aid stuff, pop cans, and also (held open) for making fine wood shavings/scrapings

- 4" section of high quality bi-metal hacksaw blade, 24tpi, rounded or sheepsfoot-ed on a grinder (actually, I suggest you include this unless told not to; when kids find out they can cut anything with these--pop cans, rope, bark/wood, fabric-- they tend to love them)

2) I suggest you add the striker from a paper matchbook to the matches (folded in on itself); even if they can't get the phosphor working in strike-anywhere use, this striker strip will make fire; it even works on matches that have been soaked and dried in the sun, with the phosphor tips wrecked beyond repair

Otherwise, keep it up, and bravo for your efforts. You are planting strong and healthy seeds ...
