As a "helping" teacher, I have to explain kids what they did not
understand in class.
I am a Dr in Engineering, lecturer, and have a pretty good knowledge of sciences & maths.
I am BAFFLED by what the ORDER in which they are learning "things" .IE: they are taught to resolve trigonometry problems of triangles BEFORE understanding Pythagor's theorem... etc... WHY??????
So, I am writing on my website (www.skytargets.com) simple lessons on "things", that are available to any kid.
To cater for that superficial "knowledge" (forgotten the day after the test) and implement a form of LOGICAL progression, I need to establish a proper CURRICULUM, starting at the early age of 7-8 to the 16-18.
Please, provide me with some guidance, where kids will be learning things that are useful, and BASED ON PREVIOUS KNOWLEDGE.
(Don't teach ax² + bx + c = 0 BEFORE teaching 1/2 + 6/5 - 1/3!)
If I have enough replies, I shall set-up a line on my website for this
purpose.
Thank to all.

Science question:
Most electric wires are made of copper and aluminum. Silver is an excellent conductor. Again, why don't we use silver electrical wires?
