This week we did an experiment making sugar crystals! Sugar crystals is a concentrated (saturated) mixture of sugar and water that turns into a spectacular experiment.

The things we needed was: sugar, skewers, food colouring, chopping board, water, access to a hob and a pot.

First, we all thoroughly washed our hands.

The second thing we did was set the hob to the hottest possible temperature.

Then, we carefully soaked half of the skewers in water.

Next, we put a chopping board down a put a little bit of the sugar onto it. Then we rolled the wet end of the skewer onto the sugary chopping board.

Once we did that, we boiled a cup of water and 4 cups of sugar (slowly, putting them in one by one making sure the water turns clear before you add in the next one). We had to make sure we were gently stirring so that the hot water and sugar mixture didn’t splash up at us.

Finally, we got two jars and put 5 or 6 drops of food colouring into one jar. Then we poured half of the mixture into one jar and half of the mixture into the other jar.  Lastly, we put the stick held with a peg into the mixture.  It was important the stick did not touch the bottom or the sides of the jar.

Now we need to let them sit for a week and be careful not to move or disturb them.
