Sabbatical

My sabbatical was Science Eureka. I enjoyed the whole course and I gained much knowledge about science from the sabbatical. On biology, we learned about fermentation, DNA and many more. We also made jelly from gelatin and fruits. The pineapple jelly was unable to set as it contains a enzyme that break down the proteins in gelatin.We also learnt how acid can affect bones as bones contains calcium bicarbonate which dissolves in acid.

In physics, we learnt about the magnets,how to make a lava lamp and density. The most interesting part was when we made a parachute to drop an egg from three floors without breaking it.We also found out that cereal contains iron as it gets attracted to magnets when a magnet is put near it.

In chemistry, we learnt about many elements and compounds. We did a lot of experiments that had interesting chemical reactions. I learnt about reactive metal and the most reactive metal is potassium and the least reactive was gold. We also saw how electrolysis works and it was fascinating as copper can be formed on one of the metal rods when two metal rods connected to a battery was put inside a solution of copper sulphate.
