We are very proud to introduce our Young Science Ambassadors!
Saskia, Charlotte, Freya, Leah, Megan and Helena are on a mission to encourage the rest of the school to love Science as much as they do.
Every Monday lunchtime they are going to be taking part in Science Club with Mrs Matthews where they will be increasing their scientific knowledge through experiments, exploration and hands-on fun!
We got very messy today making our own oozy slime. We did this by using cornflour, water and food colouring. We added water to the cornflour and food colouring slowly until we had a very thick creamy mixture which felt like a stiff liquid when we were mixing it with our hands. We were amazed at how it felt a bit like rubber when we had finished mixing it, but when we squeezed it between our hands it changed so it felt soft, similar to plasticine. Almost immediately after we stopped rolling and squeezing it it flowed out of our hands like a runny, messy, oozy slime!
We investigated the science behind our slime and found out that when you mix cornflour and water together it forms what’s called a suspension or colloid: Tiny, solid particles (of cornflour) suspended in a liquid (water).
Today our Young Science Ambassadors led an assembly in which children from Years 1-6 took the opportunity to celebrate the exciting Science that classes have undertaken this term. It was a real pleasure to see the children sharing their learning in:
Today we had fun carrying out an experiment where we transformed old dull-looking pennies into pennies that became bright and shiny! We did this by putting the penny into a bowl of tomato ketchup (making sure it was completely covered) and leaving it for three minutes. We then had fun getting messy fingers by rubbing the sauce into the coins for another thirty seconds. The next step was to use water to rinse and clean all of the ketchup from the penny.
Finally, we dried the penny with a tissue. The results were amazing! Instead of dull-looking coins, we had money that was so shiny we could almost see our reflection in them! We learnt that the salt plus the acid in the tomato sauce formed hydrochloric acid and this reacted with the copper.
Why not try this at home?
