We have been keeping a close eye on our terrariums in class.  Watching to see if the water cycle is still taking place inside the jars.  When we set them up we knew that it was an experiment that we were conducting and that we had to wait and see it if would work with the materials that we used and with the conditions created inside the jars.

Here are some photos of our plants 5 weeks after they had been planted in our terrariums.

As you can see our plants are still alive and there is still moisture in the environment created within the jar.  It worked!!

Some of us poured out a little water half way through as we had put too much in to begin with.  Through observations and evaluations we have achieved success!

Following on from our work on the Water Cycle, we decided to carry out a scientific experiment to see if we could create a water cycle model inside a glass jar – a terrarium.  Mrs James explained that as we were sealing the jars with the lids, this would create a tropical environment within the jar.

We collected small stones for drainage, we gathered soil and moss to help absorb excess moisture.  We then planted small fern plants inside the jars.

Hopefully, the water will evaporate, causing condensation on the surface of the glass which will then drop back onto the fern to water it.  As it is an experiment we will need to wait and see if it works!

 

Over the last few weeks we have been looking at the Water Cycle.  Today we went outside and created models of the water cycle using natural materials and tinfoil as the water.

Have a look at what we created!
