Jhonrave and Rian used a chemical reaction between vinegar and baking soda to inflate a balloon! They mixed baking soda and vinegar inside a bottle and attached a balloon to the top opening of the bottle. When the baking soda and vinegar mixed, they created carbon dioxide. This gas began to expand the bottle and because it had nowhere else to go, it began inflating the balloon too.

Poppy and Shirley showed us an experiment with skittles and warm water. They separated skittles by their colours. They put two of one colour, three of another and so on into separated containers and soaked them in warm water for a few minutes. Then using a pipette, they gathered up the residue, colour by colour. They began with the colour that they used the most of. Then, they place the colour they used the second most of in and so on. This created a Skittles Rainbow in a jar because the bottom coloured skittle, which had the most skittles, contained the most sugar. So, it was denser and didn’t rise or blend with the less dense skittles above.

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.
