Year 10 created 3D lolly models of DNA strands last week in Science.
DNA strands are in the shape of a double helix, which resembles a twisted up ladder.
Gummy bears represented the “rungs of the ladder”, which are the different nitrogenous bases; Adenine, Thymine, Guanine and Cytosine bonded together.
Students chose whether to use red liquorice, sour straps or snakes to create the sugar phosphate “backbone”.
They had to plan their model in advance, then make improvements throughout to maintain structural integrity as they twisted up their “ladders” to represent a DNA strand.
