Today’s class is “Environment and health” and we learned how the increase of pests, flood, rising ocean temperature, and destruction of ozone layer make effect on human health. 

 

 

After the class, we dyed a handkerchief with natural color.

 

 

First of all, let’s see the materials.
There are hotplate, handkerchief and red alum which make easy for dying.

 

 

Let’s see the process of natural dyeing. 
First, put alum inside the water, and put the handkerchief into the water.
Second, squeeze the water out from the handkerchief, and tie it with a rubber band so that you can make your own pattern and design.

 

 

 

Third, if the water boils, put the alum inside and make a color.
If red color comes out, put a handkerchief into another container and pour the dyed water with filtering layer on the top of the container.

 

 

 

Fourth, take the filtering layer off and wait a second for dying.

 

 

Fifth, complete!

 

 

Students dyed it well and clearly. Easy Natural dyeing!
We are happy because we are together with Jangseung Middle School students.
