Some of the experiments were exploring densities, this first one is to recreate a kind of Lava lamp. They started by pouring water and oil into a jar, waiting for the liquids to separate then they added food colouring and salt. The salt dropped through the oil layer talking some oil with it, after the salt dissolved the oil returned to the top in what looked like bubbles. We have added a short video to show this in action.
The next experiment was to create the look of fireworks in a bowl of water. They first mixed oil and food colouring together and poured the mixture into a large bowl of water.
The oil and food colouring mixture rose to the surface but after a few minutes the food colouring began to sink down and look a little like fireworks, or streaks of colour. We have added a short video to show this in action too.
There was also a fizz bomb experiment but that really didn't work at all well. They then tried out the volcano experiment with vinegar, food colouring and bicarbonate of soda. The first time they tried not much happened at all, just a bit of a trickle, it was a bit of an anticlimax so Dad added more ingredients, this time it worked much better... a little too well.
So well in fact that it left a big red stain on the ceiling! I have spared you the video on this experiment as there was a lot of screaming.
We have enjoyed some lovely nature walks looking at all the leaves changing colour and the jewel like berries and visits to the beach for Autumn beach combing.
Also a trip to the local sea life centre, where the children watched the rays for what seemed like hours and got the chance to see the turtle having his lunch.
