A series of links for World Space Week 2020. Designed to spur exploration. The truth is out there…

Trigonometric Ratios from first principles & pythagoras’ theorem. Set in context of tracking a star orbiting an Earth assumed to be flat (as it seemingly was at the time the principles were first developed!).

Something inspired by thoughts on sun dials and a once-held belief that the world was flat; possibly a flat disc floating in water. In essence it may provide (at least) a "holding" answer to an old teenage question: "If zero degrees is north (a.k.a. "up" on a 2D map) for bearings questions, why is it east for more advanced trigonometry?". The STEM-Ginger Beer Glass answers a separate (but related) question (or begins to).

A gentle starter for those beginning to grasp proportionality. It enables extension by encouraging pupils to design their own questions (with answers). Proportionality is visualised using a familiar item (macaroni) that they may see at home. Recognising that such a familiar item may be used in this way may lead to experimentation beyond the classroom.

Translations-based code word revelation.

**A couple of poems with a few mathematical questions. Nothing too heavy; but enough to spur some thought.
