The discovery of fire changed the way people lived. First, it allowed them to live in cold climates since they could stay warm especially at night. Second, people were able to cook their food. This made it tastier and healthier. It also killed dangerous bacteria in meat. It even changed the way carbohydrates affected brain growth. It actually made humans smarter. Early people used fire to make jobs easier like bending metal for tools. Fire also kept away predators or wild animals. Fire extended the day because people could see in the dark. Finally, all of these together helped people to live longer. On your study guide, fill in the notes on how fire changed they way people lived long ago.
Agriculture is another word for farming. Both of them mean raising crops & animals for food. Early people realized they could plant seeds and harvest a crop if they planted at the right time and kept them watered. This discovery also greatly changed the lives of early people. First, they could stay in one place. They didn't have to roam around and hunt for food. Second, it gave them a surplus or extra supply of food. Early people would store this in a safe dry place to eat later. Third, people had more free time. They did not have to spend long periods of time hunting for food or worrying how to survive. This allowed them to specialize in one skill. So, humans got jobs. Yep, this is how humans got jobs. Some learned to build things, others to write and record information, some were soldiers, and so on. Because of farming, the population got bigger - this means there were more people on Earth. Eventually, larger cities were formed.
People that lived long ago are sometimes called cavemen because they lived in caves. They might also be called primitive man because the word primitive means early or beginning. We will watch the fun episode below of middle school kids that can travel through time with the help of "The Book".
These kids warp back to early times when people lived differently. Jodi ends up in a cave and loses the book. When they trade Jodi's binoculars to get it back something goes wrong. They have to make sure they don't change the course of history and get back home safe.
