Our homeschooled children have been experimenting! The students aged 10-11 used electricity to split water into its two elements, hydrogen and oxygen. Although the oxygen remain dissolved, they saw evidence of the hydrogen ions. This process is called Water Electrolysis.
Our home-schooled girls aged 13-14 have been ‘Raising- Standards’ in their science experiments! The group enjoyed a fun session at the Tuiton club making Pancakes. Ever wondered what does science have to do with pancakes?.. well, when you make pancake batter you are mixing a whole range of different chemicals – so all sorts of reactions take place in the cooking! The dry ingredients contain flour and sugar, as well as salt and maybe either baking powder or baking soda. Flour supplies protein, molecules made of lots of amino-acids joined in chains, along with starch, which similarly is made of lots of simple sugar molecules joined in chains.
Our home schooled children in year 3 and 4 have been learning all about fossilization during their science lesson. The children have learnt that fossils are the preserved remains or traces of living things from the past. There are many ways to form fossils. The experiment conducted by the children modelled the casting and moulding method. The dent made by the object, in this case were mini- dinosaur figurines in the clay is the mould. It shows the detail of the object’s surface. Groundwater leaks in to the moulds and then evaporates, leaving minerals behind. The minerals dry up and harden and this creates a cast. The children went on to pour pva glue into the moulds and baked in the oven to harden up to reveal their very own fossils!
