I use this as an introduction inquiry lab in my one semester general elective high school science: Marine Biology.
We start by brainstorming on the first page of questions about water and why it is important. We talk about why organisms need water, and make choices about which animals we think need more water in their bodies and why.
In my class we have already discussed Estuaries, so students are familiar with the idea that animals have adaptations and that not all animals will be able to react to salt water the same way.
Students are given the challenge to find out what percent of water makes up a living organism. We discuss how to find that out (the students have some creative ideas).
I use a carrot as the model organism, so that we will not have to “kill” anything in class. You could use any organism that you wanted that students can try to dry out.
Students brainstorm different methods of dehydrating the carrot
Shredding, cutting in small pieces, cooking, boiling, dehydrating in the sun, etc.
You will receive a 6 page Word Document. The first 4 pages are printed and shrunk front/back to create a foldable to glue into the student notebook (back page is blank). Then there are 2 pages of teacher notes and a rubric.
