7、agnesium burns in air.第四步：句式升级造亮点1用with复合结构改写句3With all these things ready, you can begin the experiment.2用thats because改写句5Thats because there is a change in weight when magnesium burns in air.第五步：过渡衔接联成篇_参考范文The aim of the experiment is to find out if theres a change when magnesium burns in air.To
8、 carry out the experiment, you need the following things: magnesium，a Bunsen burner, a balance and a crucible. With all these things ready, you can begin the experiment.First, put the magnesium in the crucible. Then put the crucible on the balance and weigh it. Next, light the Bunsen burner and hold the crucible over it. Finally, weigh the magnesium again.You can see that it weighs a little more than before, Thats because there is a change in weight when magnesium burns in air.
