Class 2 recreated Cornelius Drebbel's submarine, using the principle that if there was air inside our model, it would float and if the air was compressed, it would sink. Using a straw, some Blu Tac, some water and a plastic bottle, we saw this effect working perfectly! We trialled the model in a cup of water to make sure there wasn't too much or too little Blu Tac, meaning that the model could float. We then transferred it into the full bottle, sealed it and squeezed (very hard!) to see the effect on the model when the air in the straw was compressed. It sank to the bottom and then floated straight back up to the surface when the pressure was released. It was so fascinating that even Mr Clarke couldn't resist having a go!
Having talked about the ways we can remain hygienic throughout the food preparation process, especially at the moment, Class 2 followed some instructions to prepare some delicious Greek feta pittas! They worked in groups, sharing the responsibilities and roles, including squeezing the lemon juice, cutting the vegetables and mixing the ingredients together. They had great fun and revised the features of instructions at the same time!
