This is a good site to use for the science of the Titanic. Lot of experiments and activities to do for all ages. Best lesson plan I found for free for science.
https://www.titanicscience.com/TitanicScience4.htm For some reason the pdf link doesn`t work on that page so I am putting that here too for the "just in case" you can`t get it. It is a WONDERFUL 48 page download.
