Scaling in a kindergarten class

In kindgergarten the students are learning measurement using inches and centimeters through cubes. They also have an unit in Science on animals. I would like to do a lesson on scale using animals and have them think about animals in comparison to others. I would start with asking them to name different animals and then put them in order from smallest to largest. Next I would have them make an observation about how many inches and centimeters each animal is. I would then  using life size shapes of some of the animals they name,  measure each animal using the centimeter cubes and large rulers. The students could compare themselves and me to the animals. They also can draw pictures of the new order, they can also measure other living objects. I would leave it open and have the lesson flow with their ideas and questions.
