Home-based: Understand Contour lines in Circles

Contour lines are found on maps as well as in art. Contour lines can be used to create an optical illusion.  

In this week's project, I used contour lines to suggest a different planet in the solar system. 
They are drawn in different colours. If you find drawing a circle difficult, look around the house for objects with a round base in different sizes. 



Contour lines are drawn in to make circles appeared 3-Dimensional. It changes a circle into a sphere. 





My little one wanted to help me draw it out on paper. So we did a wax-resist technique with oil pastel and diluted paint that has been simplified for a pre-schooler. 



Step 1: With oil pastel, draw different sizes of circles on the paper. 
We pasted three sheets of paper together to get a long composition. 


Step 2: Fill in each circle with contour lines and add in the rings on some planets. 



Step 3: Add dots to the entire piece of paper. These represent stars. Q did random dots, if you are a solar system expert, it would be interesting to use this step to dot out an alignment of stars.  




Step 4: Time to paint
