                                 What are we going to learn today?




                                 I will tell you about natural and human-made things and more.



                  Nature offers us natural things like plants, birds, butterflies, rocks and
                  so on. They are not made by humans.

                  A chair and table are not natural things; they are human-made.
                  There are things that are not natural but made by humans.
