Crustacean Art.
Why not consider doing some crustacean art at home?
Draw your design using ideas from https://www.nationalaquarium.ie/aquakids.html and then learn more about exoskeletons from Stephen in Co. Wexford, who took part in Marine Broadcasters 2020 https://www.youtube.com/watch?v=KolweKZTxZM…
Send them in to your class teacher when you have finished!
