Question 92
Scientists often try to make sense of large amounts of information by grouping similar things together. For example, they group similar types of animals together such as mammals, fish, insects and so on.
The same happened with the elements as more and more were discovered. Three important scientists contributed to the Periodic Table that we use today.
Your task is to make a report, a presentation using slides or a presentation in any other way to explain and describe the development of the Periodic Table. You should stress the way that scientists collaborate, building on the work of others and changing their ideas when they have more information. You can do this in groups of two or three.
The book's timeline gives: 1817, Johann Dobereiner, ‘law of triads’; 1864, John Newlands, every eighth element had similar properties; 1869, Dmitri Mendeleev, modified and extended John Newlands's work.
