Use a Jenga set as a scientific model of a marine food chain to teach kids about food webs and the delicate balance of the ecosystem in a fun way. This activity introduces kids to contemporary environmental issues regarding the marine ecosystem. You just need a Jenga set, credit card envelopes, self-adhesive paper, some heavyweight paper, scissors, and glue.
We need information about the schools using our model, that’s why we’re asking you, before you download our materials, to kindly fill out this brief form, and tell us a bit about yourself and your interest in our tool. Clic on the image below:
