Mining Limestone by Frost

Today we went mining for limestone. We didn't know what it was at first so we had to take some bits to my Grandad. He is a geologist and biologist so we took it to him. He said it wasn't limestone. He said it was a white chalky substance. So we went and dug some more. Eventually we found a big cave of it and we took some off and put vinegar on it and it fizzed and bubbled and you could see tiny bubbles. If you put it close to your ear you could hear it fizz. Only limestone fizzes and bubbles. The first limestone we found was white and powdery. But then WREN found that another rock that was grey is also limestone and it fizzes and bubbles better.

The pictures below show Wren and me at the rocks. We hammered them out. Wren hammered the rocks on the ground and then imagined he broke them. He is on granny's PRIVATE road. Shannon is looking over us.



This next picture is Wren being a geologist. He pours vinegar, listens to the fizzing and hammers his rocks.

Listening for fizzing:


I have a ph and chlorine tester. It turns out that normal has a 7 rating but Granny's water has a 7.2 rating which means its a bit alkaline because it is over 7. Their water comes from a well and water with crushed up limestone in it has somewhere between 7.8 and 8.2 rating. Probably about an 8 rating. That is quite alkaline. We crushed up the white limestone, put it in the small tube and then put 5 drops of the red Ph test in the small tube and then we shook it up and looked at the colors. It looked about an 8. I subtracted 2 from the 8.2 and added 2 from the 7.8 because it was between them. See. Here is a picture of my test for the experiment with the limestone.



The Terrible Worm Squash
This morning Wren found a millipede inside and was looking at it. Frost decided to keep it in a box and feed it. He asked Mervyn what they ate because he is studying invetebrates then he went outside and began collecting food for the millipede.

While outside Wren put the millipede inside a book and squashed it. "I go snip snap and he is squash!" said Wren.

Frost was in tears. He is still too upset to talk about it.

That is why I cannot write more about it on this blog post (per Frost's instructions). Wren is in the doghouse but shouts triumphantly "I SQUASH 'IM!"
