My school is leadership skills, and we've started having leadership groups where multi-grade level students are grouped with teachers to hone in on a topic of interest in which they can become a leader. I have seventeen 3rd, 4th, and 5th graders in my group called the Clay Kid Leaders. We are focusing on creating functional ceramic work that can help ourselves or others.
We just made these cool night lights. They are meant to sit on a bathroom counter or maybe a dresser with an LED tea light underneath. We made the form by wrapping a thin slab of clay around a school paper towel tube. We then used another slab to close off one end. The kids then poked holes in them and added designs.
