Weekly competition and Art work of the week.

The last weekly question proved to be quite tricky for everyone and was up on the wall for 3 weeks until a group of grade 5's figured it out. The answer was Mola. The grade 3's had been making their own Molas inspired by traditional craft from Panama.
This weeks question is:
How did the grade 2's make the bubbles on their Under the Sea pictures this week?
