This was a fun warm and cool color study with 3rd grade. We used liquid watercolors with dish soap and students printed bubbles they blew from a straw. I had them partner up on this, one student blew the bubbles and the other printed, then they would flip so each got to blow bubbles and print, (have partners choose two different color straws so they don't get them mixed up!). I did one table at a time so I could monitor the printing and help more readily. While one table printed the other tables water colored their backgrounds with cool colors. If they were done with water colors, they could move on to the tentacles of the jellyfish, which is warm colored tissue paper. I encouraged them to add lines of glue rather than dots, the lines looked more like part of the tentacles. As the bubble paper dried, they drew out the jellyfish head on the back, and added it to the paper. I asked each student to outline with two warm colored sharpies.
