Asanda’s grandfather likes to bake his own bread. Asanda noticed that after he makes the dough, he then leaves it in the sun to rise. Asanda wanted to know why it was necessary to leave the dough in the sun. She thought that it might have something to do with temperature. She decided to conduct an investigation. She made some dough with 100 g of flour; 2 g of sugar; 4 g of dried yeast and 25 ml of water at 38 ºC. She placed 10 ml of dough into each of three measuring cylinders. One cylinder was kept at 5 ºC; one at 20 ºC and the third cylinder at 35 ºC. Asanda then left the cylinders for 20 minutes and measured how much the dough had risen in each cylinder. She recorded her results as follows: TEMPERATURE (ºC) VOLUME DOUGH ROSE (cmᵌ) 5 15 20 25 35 35 12.1 Formulate an aim for Asanda’s experiment. __________________________________________________ __________________________________________________ (2) 12.2 Do you think this was a fair test?
