Pair students and give each pair a paper bag and two or three plastic bags. They can use the paper bag for all other items, such as rocks or leaves. As a class, examine each item and discuss whether it is living or non-living. Some things may be tough to classify. Add these drawings to the appropriate boxes.
Older children can list each item on the chalkboard under the appropriate classification.
Then ask students to make a bar graph comparing how many living versus non-living things they found. They excrete or rid themselves of unused materials and waste. They grow and develop. They respond to stimuli.
