My daughter needs small weights for her 7th grade science fair project, are these appropriate or for small children only?

They are NOT accurate. I have a digital kitchen scale that I have no reason to doubt, and the 1 gram pieces weight under while the 10 and 20 gram pieces are over. Do not expect accuracy for any purpose, including between themselves.

What is the total weight for all combined pieces? I'd like to use these in a ship building activity- are they waterproof too?

There are 54 pcs, totaling 300g. 20-1g, 20-5g, 10-10g, and 4-20g. Yes they are waterproof as they appear to be of a coated resin /plastic composite. Good quality.
