Crystals

This week for our science experiment we created sugar crystals. It was really fun to make them, especially when we do get to eat them and see how well we made our mixtures.

Aim: To create sugar crystals

Equipment: Beaker, Sugar, Water, bunsen burner, food dye, cup, popsicle stick, measuring cylinder, something to stir with, tripod, heat mat, gauze mat, lighter.

Method:

1. Wash equipment

2. Add 50 mL of water into the beaker using the measuring cylinder.

3. Set up your bunsen burner and set it up. put the beaker on the tripod and on the bunsen burner. 

4. heat up the water to boiling point, then turn off the water so then you can add the sugar.

5 Gradually add sugar and stir it until it dissolves, then add more and repeat until you have a clearish liquid. 

6. grab a popsicle stick and dip it in water, then dip it into sugar so then as the crystal is growing it has something to stick too.

7. Grab a cup and put the popsicle inside of it, this is where the crystal will grow.

8. Add food colouring if you want and then pour in the liquid into the cup. Place it near a window to dry and grow.

9. wait a week or more then check how much your crystal has grown.

Results: The mixture looked really good even though we have only left it for a day, it is crystallising very well and it also looks very good. 

Conclusion: The mixture was very saturated, Saturated means when there is a lot of water in a mixture or item to the point that it can no longer absorb any more. We need our mixture to be saturated because when the water has started to evaporate the sugar will crystallize over time, we can't rush the mixture because it won't actually crystallize as well. The crystal grew very well and ended up looking cool as well.

Here is a photo of the mixture before and after.
