As part of their learning to make predictions and observations in science experiments, these children explored making fizzy potions outdoors. They measured vinegar and washing-up liquid in to a container then decided what to add to make a range of different fountains – various food colourings, stars and glitter were all very popular. As with all good potion mixing, they children had to give their concoction a good stir and a few magic words before adding baking soda to produce an exciting fizzy fountain. As you can imagine, we tried this out several times and used different quantities of ingredients each time to observe what happened. The children showed good focus and made some great comments as they observed the process.
Sophia: it explodes. It’s green. I mixed it.
Jack: I was doing a scientist. I put sugar in it and it makes bubbles. It explodes like a volcano. Mine was yellow bubbles with lots of stars.
Aoife: I’m making a volcano like where the lava comes out.
Letti: I put stars in the mixture. It was really high. The stars came out into there.
Emilia: we add vinegar and washing machine shampoo. It grew really high. It exploded!
Freddie: we used a spoon to mix it. It blows up.
Emily: I’m making an experiment. I’m a scientist. I was making potions. It exploded.
Arthur: I’m making a volcano. It was big and blue. I am a scientist.
Leigha: I’m stirring it with the spoon. It can get out big.
