What do you know about Chemistry?

The science that concerns the study of matter, its structure and the changes in composition that matter undergoes is

• Biology

• Chemistry

• Ecology

• Physics

When a chemist carries out an experiment, the substance that is being tested is called:

• sample

• law

• theory

• variable

After making an observation and proposing a hypothesis, the next step of a scientist should be:

• ask other scientists for advice

• carry out experiments

• analyse the data

• state the conclusion

A famous chemist, who established the science of Modern Chemistry, said: "One may take it for granted that in every reaction there is an equal quantity of matter before and after". Who is this famous chemist?

• John Dalton

• Alexander Fleming

• Robert Boyle

• Antoine Lavoisier

Scientists gather information using their five senses. What do they do?

• state their conclusion

• gather data through observation

• formulate hypothesis based on the gather data

• measure the exact quantity compared to the other quantities

The scientific method of solving a problem follows the sequence:

• hypothesize, concluse, experiment

• hypothesize, experiment, conclude

• conclude, hypothesize, experiment

• experiment, hypothesize, conclude
