Aliama and Laura taught us about the heart. They made a model to help us understand how the heart works, as well as a diagram. Then, they showed up how to check our pulse. After some brief and speedy exercise, they asked us to check our pulse again to see how fast our hearts were now beating!
Amelia, Daniel and Tyler showed us an experiment using skittles and water. They placed skittles around the outside of a plate and added some water. Skittles are coated in food colouring and sugar. When you pour water over the skittles the coloured coating dissolves spreading through the water. The colour and sugar dissolve into the water and then diffuse through the water, making it the colour of the skittle.
Sadhbh and Robyn demonstrated rain using shaving foam and food colouring. On top of some water, they sprayed shaving foam (to represent the clouds), they gently added a few drops of food colouring (to represent rain). When the cloud gets too heavy, the drops fall through as rain! When water droplets grow heavy in the sky, gravity pulls them down from the clouds as rain, just like in the experiment.
Georgia, Maeve and Noah created a model of a volcano. They then used this to show us differing reactions between Coca Cola and a variety of mentos sweets. We discovered that the spearmint mentos reacted better compared with the fruity mentos!
We used vocal sounds and body percussion to create sounds effects to a nocturnal scene! We made noises to show owls, rain, thunder, footsteps, leaves rustling, wind chimes chiming etc.
Tommy demonstrated that his whiteboard marker was insoluble (wouldn’t dissolve in water). He drew a stick man inside a transparent bowl. Then he added some water. He gently tilted the bowl back and forth until the stick man began to float, intact, on the top of the surface of the water.
Lucy showed us a chemical reaction. She mixed vinegar and bicarbonate of soda in a ziplock bag. This reaction caused the ziplock bag to open!
Room 3 had great practice with some new adjectives, as we passed out compliments to one another!
Room 3 have thought of some fantastic Green School Committee slogans!
