Kinetic Sand

This week in Science club we experimented with regular play sand and kinetic sand.  Kinetic sand is 98% sand and 2% polydimethylsiloxane (a type of silicone oil) that mimics the physical properties of wet sand.  We added the sand to water and it floated! As we added more sand, the sand began sink yet it didn't get wet! We even managed a magic trick, where we dipped a pencil into the sand yet the pencil remained dry - cool huh?!


 Regular sand - sank straight to the bottom and stayed there!






 Yet the kinetic sand did not sink. It floated at first, and then as it began to sink, it created swirling patterns.

Science Club is back with a..... squelch?

Science Club returned on Friday 12th January 2018.  Armed with borax, PVA glue, water and food colouring we set out to make slime.  After a BIG failed attempt, we switched glue and luckily it worked!



























SLIME-TASTIC!

Alka-Seltzer Rockets

For our last science club session we released Alka-Seltzer rockets outside the classroom and also did the classic coke and mentos challenge. Well done to all of the children in science club for being such fantastic participants over the past few weeks.
