In sugar rainbow experiment we want our students realize that olored sugar, solutions, made at different concentrations can’t be mixed. The solutions form layers, from least dense, on top, to most dense (concentrated) at the bottom of the glass.
What You Need:
1. sugar
2. water
3. food colouring
4. tablespoon
5. 6 glasses
6. measuring cylinder 100 ml
7. syringates 50 ml
Here's How:
Line
up six glasses. Add 10g of sugar to the first glass, 20g of sugar to thesecond
glass, 30g
to
the third glass, 4 g to the fourth glass and 50g to the fifth glass. The sixth
glass remains empty
Add
water to each glass until 100g. Stir each solution.
Now
we colour the sugar solutions using food colouring
0% w/w
|
red
|
10% w/w
|
orange
|
20% w/w
|
yellow
|
30% w/w
|
green
|
40% w/w
|
blue
|
50% w/w
|
Dark blue
|
Now let's make a rainbow using the different density
solutions. Fill measuring cylinder with 20 ml dark blue sugar solution.
Carefully layer 20 ml blue sugar solution above the
dark blue liquid
using the syringates.
Now layer 20 ml green solution above the blue liquid and continue with yellow and
orange solution.
Finally, layer the red solution above the orange
liquid.
That a very cool experiment!
ReplyDeleteWe have this experiment in the class , and this is very cool ! I tried to reproduce it at home but I didn't really succeeded.
ReplyDeleteThis experience is very cute but it is not dangerous so not very funny :)
ReplyDeleteIt's very cool and beautiful!
