💡 Horizon: Explaining How & Why
Opening lesson of the science module. Learners build cause-and-effect explanations for everyday phenomena, mastering the direction of causal phrases (cause → leads to / results in / causes; effect → results from / is caused by), the because-clause vs due-to-noun trap, and multi-step why-chains with which in turn and as a result. In the story, Coach Deniz unveils the Wonder Wall and bans “because science” as an answer; Aylin chains the blue sky and red sunsets link by link, Sam discovers his onion tears are due to salad, and the chain-length contest crowns a five-link bread explanation.
