As part of STEM week, the children have taken part in a number of activities. We looked at friction when they had to pick up jelly cubes using chop sticks. They then had to repeat this after dipping the cubes in vegetable oil. The oil blocked  the force of friction making it quite tricky. They made invisible messages by painting using lemon juice. When it had dried, they looked at the paper using a light and some could see their messages. This is because the lemon reacts with oxygen turning it slightly brown and allowing us to see it. They also had to make the tallest tower using just paper cups and then build a structure using pegs, lolly pop sticks and clips to hold a tray of 100 pennies. It was a lot more challenging than they were expecting! Lots of teamwork involved, an excellent effort all, da iawn.
