Science Chicken
These chicks are created along with 2-3 year olds, but can be just as exciting for the largest. A simple Easter activity that creates wonder for young and old.
The chicken made of salt for a coffee filter to solidify. On the surface formed salt crystals that provide a wonderful and exciting effect. Confectioner color stock the yellow top. At Christmas you can create goblins with hat by using red color.
How do you go: & nbsp;
1) Fill a measuring cup with 50mL lukewarm / hot water (we have used laboratory equipment. It makes the experience more exciting and can be recommended as an investment, but ordinary glass can certainly also be used) & nbsp;
2) Allow the child adding 3 teaspoons fine salt and stir until the salt is dissolved. Magical for young children, where it has become the salt? & Nbsp;
(It does not matter if it is a bit of salt in the bottom of the glass. The main thing is that the water is saturated)
3) Add yellow food color.
4) Put a coffee filter into the jar as shown in the picture. The bottom should be facing the same way as when it is put into the coffee machine
5) Wait 2-3 days to slatoppløsningen is evaporated. Place gladly jars in a window with a lot of solar heat to shorten the waiting time. & Nbsp;
6) decorate with eyes and beaks
is the evaporation that draws water into the air cleaner and the crystallization takes place at the top. The large surface allows evaporation increased. Top with a free glass filter and see the difference.
Here there is much to marvel over.
Have fun and happy Easter ??
