For week 2 of STEM Club, we were making and testing toothpaste! The children were sent a letter from The Bright Smile Toothpaste Company asking them to make and test their new recipe of toothpaste. The children followed their recipe and mixed their ingredients together well, adding colouring if they wished to do so, before putting their creations to the test! The children had whiteboards that had been stained with permanent marker pen. They used their creations to see if they worked well enough to remove the stain. They all did really well and managed to remove the stains so the whiteboards were sparkling new! Well done, STEM Club!
