Water Cycle Terrariums

We have been learning about the water cycle with a focus on evaporation, condensation and precipitation. To understand more about this process we decided to make a terrarium. This way we could observe first hand how the water cycle works. Similar to the way water evaporates and rises into the atmosphere before condensing and falling as precipitation, in our terrarium, the moisture from the soil evaporates and rises before condensing on the top of our container. It then falls (like rain) to provide moisture to the grass in our terrarium.

It was amazing to witness the water cycle happening right in front of us. Not only did we learn more about evaporation, condensation and precipitation, we also learnt about transpiration. Transpiration occurs when the grass soaks up the water in its roots, then ‘breathes’ with respiration, releasing the water (and oxygen) into the air which then condenses on the container and rains. Amazing stuff!!

 

Riley the Magician

Today Riley performed a magic card trick for our class.  He had us mesmerised and amazed.  We couldn’t believe our eyes, it really was MAGIC….

How is a Rainbow Formed?

This week in 2KR we have been learning about how rainbows are formed. Did you know that rainbows happen when sunlight and rain combine in a very special way. The beams of sunlight separate into the colours we see in the rainbow as they enter a raindrop. Sunlight is actually made up of different colours that we don’t see.

Today in class, we tested this out by shining a torch light on a mirror that was sitting in a large glass jar. The torch light bounced off the mirror and reflected onto a piece of white card that was held over the jar. We were amazed to see the colours of the rainbow on the white card. The children were also very excited about finding out if their families knew that a rainbow is actually a circle shape, not the semi circle that we usually see!
