Saturday Science

 January 27
Making compost

In this activity the girls were shown how to make good compost and how decomposition works. Their bottle of compost is sitting by the herb garden in the sun and almost two weeks later is coming along well.  It smells great - loads of microbes happily aerobically decomposing.

Making an Abacus

Saturday Science became Saturday Maths this week, as P wanted to show the girls how to make their own abacus.  In the end they made a soroban instead - the Japanese version which is slightly less complicated than the traditional Chinese abacus.

Finished! 

 Our sorobans have seven Heavenly Beads and twenty eight Earthly Beads.
