Coloured flowers.

First we cut some flowers.

Then put some red food dye in a jug and some water in another jug.

We left it for a bit and when we looked at it again the flowers had turned pink.

We wanted to see how the water got up the stem from the roots.

Our special Worm World.

At first, we were digging in the Class garden for potatoes. We found 8kg of potatoes all together. Then we accidentally found a worm and picked a worm wrangler to make sure the worm didn't get hurt. Then we made a wormery to find out how a worm moves and finds its way around.

To make our wormery, we got some soil and put some sand over the top. And we kept on putting soil then sand, soil then sand so it would be easier to see how the worm moves.




"The worm felt all slimy and stiff", said the worm wrangler. "It was stretching and trying to get out of my hands."



We put the worm in the wormery and left it overnight. The wormery has a special cover to keep it dark. When we got back we looked at the wormery and the worm had moved.



This photo shows the gaps where the worm has been digging.




Then we put some water in the wormery to keep it alive, because when it rains they get water in their soil. We put some old parsley leaves on the top to let it have something to eat.

Erosion experiment.

One of our topics this term has been "Water". We've looked at pollution, floods, drought, rainfall, and important scientists like Dr John Snow, Robert Koch, Louis Pasteur and Joseph Lister.
This was a water experiment to show how trees help to prevent erosion. Erosion is when rain hits the ground really hard and farmland gets destroyed.

First of all, we got two trays, next we poured soil into the trays.

Then we cut some straws up and put them in one of the trays of soil. Then we put some fluff on the top to make it look like the leaves on trees

We got a plastic cup with really big holes in the bottom. We had to tape some of it up on the bottom. When we poured 500ml of water through the cup, it looked like real rain.
First we started on the tray with no straws in. The soil went all squelchy and it had mud slides. It looked like a swamp.

When we poured the water on the fluff, the fluff stopped a bit of the water getting on the soil. A few of the trees collapsed. When we took the fluff off and looked down, it looked a lot drier than the other tray.
