Getting back our tests!

Today in class, Mr. Schick called up each one of the students and gave them they're test back. The teacher enjoys passing back the test in a unique, funny way. He has a bell on his desk, and when a student does very well on a test, they get two dings, when they do well on the test, they get one ding. Unfortunately, I didn't receive a ding, which means I didn't do so well. I will be retaking the test though, for a better grade. Afterword’s, each person called out an answer from each row for the test. Then, we took notes on a brand new (to us) PowerPoint. The slide presentation was called 'From Prehistoric to Civilization'. Hunters/gatherers, Mesopotamia, and Ancient Egypt. Before civilization: The Prehistoric Era. The origins and "Ages" of Human begins. 20,000 years ago, a human species emerged in Southwestern Africa. 14,000 years ago, a worldwide human race existed. Earliest prehistoric age is the Paleolithic Age (Old Stone Age). Neolithic Age (New Stone Age) was marked by advanced tool making and beginnings of agriculture. Initially, humans were parts of migratory groups which hunted, fished, and gathered plants for food. The Prehistoric Era, The Agricultural Revolution=Neolithic Age.
