- Suppose you are trying to get lemon juice and you have no juicer. Some people say that you can get more juice from a lemon if you roll it on a hard surface, applying pressure with the palm of your hand before you cut it and squeeze out the juice. Others claim that you will get more juice if you first heat the lemon in a microwave and then cut and squeeze it. Apply the methods of science to arrive at a technique that will give the most juice from a lemon. Carry out experiments and draw conclusions based on them. Try to generate a hypothesis to explain your results.arrow_forwardWhat is meant by the statement Macroscopic observations have molecular causes?
