Binoculars, refractor or reflector: a first telescope for a child
What each kind shows, what it costs, and why we often suggest binoculars before any telescope.
Why we teach robotics with a soldering iron
Block coding is a good start; wiring a circuit yourself is where it clicks.
Most robotics classes for children run on screens. Children drag blocks, press play and a robot moves. It is a fine way to begin, and our level 1 course starts that way too.
But something changes when a child wires the circuit themselves. When an LED does not light, they have to find out why: a wire in the wrong row of the breadboard, a resistor the wrong way round, a loose joint. That search is what engineers do all day, and children learn it fastest with their own hands.
We introduce soldering at 11, in the Electronics and microcontrollers course. Every child wears safety glasses, irons sit in stands with a mentor at each bench, and the first joints go on a practice board. By the fourth week, most can solder a sensor to a header neatly enough to use.
By the end of the term each child has built a weather station that records temperature and humidity on our rooftop. Parents usually ask why it took 16 weeks to make something they could buy. The answer is on the board, in the joints their child made.
