Letheringsett Watermill

We went to Letheringsett Watermill to have a look at how flour is made.  We saw the different cogs which move the stones and through the glass we could see the watermill moving too.

There were some scales which are used to weigh the bags of flour.  The lady showed us the flour they were making and the shoot it comes down to go into the bags.  The day we went they were making whole wheat flour which felt courser than white flour as it used all of the grain.

The stones are used to crush the grains and they have a different gap depending on the different flours they make. They are closer together to make finer flours. The lady then showed us some stones which had been used before.  They were very ground down.

The flour they make in this mill is sold in the mill shop and also in local shops around the county.

It was a very interesting day.

Science – DNA

In January we had a special science lesson with a DNA expert.  She explained all about DNA, how many there are, where it is, what it looks like and how big it is (it’s tiny).

We then did a DNA extraction experiment. We were extracting DNA from a banana. Firstly we had to peel, chop and crush the banana.

We then added some warm water and mushed the banana some more.

We then filtered it into a beaker so we just had the liquid.

When we had just the liquid, the lady added some pure alcohol to it.  This caused the DNA strands to separate from the liquid.


The DNA strands floated on the top of the liquid.


They separated instantly from the liquid once the alcohol was added.

This lesson was lots of fun.
