We mapped the x<\/i> and y<\/i> coordinates onto the flat disc <\/span>first and then used barbecue skewers (painted <\/span>black) trimmed to the correct length to represent the z<\/i> coordinates.<\/p>\nThe stars, represented by coloured beads (also painted beforehand), were attached to the skewer ends. Our stars in this project are not to scale \u2013 if they were, they would be microscopic!<\/span><\/p>\nWe displayed the model on a simple stand so it is aligned with the plane of our Solar System, but you could easily adapt it to be a hanging model.<\/p>\n
Tools and materials<\/strong><\/h1>\nA piece of sturdy cardboard, measuring 30cm x 30cm, plus a piece of graph paper the same size \u2013 we stuck two pieces of A4 graph paper together.<\/p>\n
Use 21 wooden barbecue skewers; 20 of 3mm diameter for the stars and a thicker one of 4mm diameter for the stand and the Sun.<\/p>\n
You\u2019ll also need 20 small black buttons, which will be glued to the ends of the skewers to act as stops for each star (excluding the Sun).<\/p>\n
Find 21 beads that fit onto the pointed ends of the skewers; you\u2019ll need 12 red, four orange, three yellow (including one for the Sun), one pale yellow and one white.<\/p>\n
A small, sturdy box to use as a base for the stand; ours measured 7cm x 8.5cm x 4cm.<\/p>\n
Make a model of our nearest stars, step-by-step<\/strong><\/h1>\n
