In class I learned about disease and how to tell if somthing is living or non-living. In class we did an expirement were everybody got a test tube with water in it but one persons test tube had a chemical in it that was supposed to simulate disease. Then we exchanged water from our test tubes with water from other peoples test tubes. Then we were able to track down who the first person to get the disease was by looking at who got the disease.
Also we made lists of how to tell if something was living or non-living. A few things that were on the list to tell if somthing was living were that it had to breath, it had to eat and it had to drink.
