For the past few months we have been observing potato plants growing in our classroom. Are potato plants living things? How do you know? (Hint: consider the characteristics of all living things) What factors affect the growth of potatoes? ((Hint: consider what what living things need to survive) Some of the potatoes are growing better than others. Make an inference as to why this is happening. How do plants connect to our lives? How do other organisms use plants? What do you think would happen if there were no more plants on Earth?
