Snowstorm in a Jar

Fourth class did an experiment called 'snowstorm in a jar'. We wrote out our method and materials in our copies to link with our genre of procedural writing in English. We used baby oil, water, alka seltzers, glitter and paint for this experiment. This experiment works for a few reasons. Because oil is less dense than water, the water will naturally sink to the bottom of the jar. When the Alka-Seltzer is dropped into the jar, its interaction with the water creates pressure in an upward direction, and the oil pushes it back down. This pressure back and forth is part of what creates the snowstorm. The other element is the interaction between water and sodium bicarbonate in the Alka-Seltzer, which generates carbon dioxide gas. 

Winter/ Christmas art

To create our Winter landscapes, we mixed a shade that we thought the sky would be on a Winter's evening using the colours blue, white and purple. We used sponges to apply the paint to our paper. We ripped another sheet of paper and stuck this on to look like our snow. Our trees are made from ripped crepe paper. We also added some glitter because we think Winter is a magical time of the year!

We also used our knowledge of pattern to create some funky reindeer. Have a look:

Our snowmen love Winter so much that they are gazing up at the stars in the night sky:

We also drew delicious looking gingerbread houses:

Reading with first class

Fourth class went into the boys and girls in first class to do some paired reading with them. Both classes really enjoyed it! 

Procedural writing

Fourth class have worked on procedural writing for the past five weeks. We decided we would create our own board games to make procedural writing more exciting. We wrote out the materials needed and the method on the back of our board games so that our classmates will be able to play them when we stay in for break on rainy days. Here are some pictures of us at work and of some of the finished products:
