DMITRI MENDELEEV (1834 – 1907) The Russian chemist, Dmitri Mendeleev, was the first to observe that if elements were listed in order of atomic mass, they showed regular (periodical) repeated properties. He formulated his discovery in a periodic table of elements, now regarded as the backbone of modern chemistry. The crowning achievement of Mendeleev’s periodic table lay in his prophecy of then, undiscovered elements. In 1869, the year he published his periodic classification, the elements gallium, germanium and scandium were unknown. Mendeleev left spaces for them in his table and even predicted their atomic masses and other chemical properties. Six years later, gallium was discovered and his predictions were found to be accurate. Other discoveries followed and their chemical behaviour matched that predicted by Mendeleev. This remarkable man, the youngest…

Wouldn’t it be lovely to have summer all year round? About 1 400 different bird species have figured out a way to do this! These migratory birds travel thousands of kilometres without a map, GPS or calendar, but they know exactly when to leave and where to go. Some species are so precise that they arrive at a specific site on the same date every year! But how do they do this? Can you eat like a bird? Birds would like to escape winter’s icy fingers as much as any human, but their real reason for migration has to do with their stomachs. Birds have a very healthy appetite, with many species eating about 20% of their bodyweight (that’s equivalent to you eating 6-8 kg of food every day). Food…

Biodiversity is all the different living things on Earth. It is the things we need to keep us alive. Everything we need and use every day is dependent on the biodiversity around us. But the biodiversity around us is disappearing as more and more people need and want more and more things. The industries that keep our society functioning causes the climate to change, which will affect daily temperatures and rainfall, and this will impact on our food and water supply. Our environment will change in unpredictable ways. Our biodiversity, making up functional ecosystems, is the life insurance we need to face changes that are happening around us. So it is critical that we protect both the species that are alive today, and the ecosystems that they live in. If…

Blue cranes are not dependent on wetlands and this allows them to be more widespread than the other crane species within South Africa. Within South Africa the species can be found in the open grasslands and the grassland/Karoo ecotone. The species is frequently found in agricultural fields and in the Western Cape it is restricted to cereal crop fields and dry land pastures. Blue cranes, despite being very social animals, are extremely territorial while breeding, driving any other blue cranes from the breeding territory. They nest in summer and the laying date can be anytime between August and April. Non-breeding birds form non-breeding flocks during this period. After the chicks have fledged, they together with the adults, join the non-breeding flocks to form large over-wintering groups.…

The mail train comes to the rescue! ln the early 1880s, problems were experienced with the transportation of mail between Cape Town and Beaufort West. The mail train was commissioned in 1883. It was a huge success and effected a huge saving in manpower. Working on the mail train was challenging The mail was loaded and unloaded along the routes and sorted between the stations. It was very difficult to render a service in the swaying surroundings. Sleeping quarters were subsequently installed in the mail wagon. The sorters sometimes worked in poor light. An oil lamp which was knocked over once even caused a fire which gutted the mail wagon completely. The two travelling staff were so efficient that they sorted much more mail on the train than their colleagues…

Meet the element: It is time to get to know some of the most popular elements on our planet a little better. Nitrogen is the seventh element on the periodic table. Nitrogen atoms love to team up side by side to form N2 at most conditions on earth. This tasteless, colourless N2 gas is the most abundant gas in the air. In fact, every breath you take is nearly 80% nitrogen. Nitrogen is an important part of all living organisms. Proteins and amino acids have nitrogen as part of their chemical structures. DNA is a kind of protein with nitrogen present in every molecule. DNA, found inside cells, holds the blueprint of organisms that is passed on to the next generation. Without nitrogen, life would not be possible. The nitrogen…

Rabbits dig burrows to provide protection during the day and shelter in cold weather. Hares are larger than rabbits and can run faster. They do not dig burrows but rest in a dip in the grass called a form. Haring around Hares depend on speed to escape their enemies. Using their powerful hind legs and feet, they can reach speeds of up to 80 kmh over short distances. They often follow a zig-zag route, or leap into the air, to confuse the predator so it loses them. Speedy breeders Female rabbits have from one to nine young in each litter, and can produce up to 30 kittens (young) each year. When born, rabbit kittens are hairless, blind and helpless. They are not ready to leave their underground nest for three…
