One strange phenomenon scientists discovered is the increase of human brain size in tandem with a decrease in tooth size. This came as a surprise; when other animals' brains grow, tooth size normally increases due to the need for more calories and nutrients to keep the brain growing. This could be because humans started to cook food over a fire which made chewing and digestion easier, saving lots of time and energy our ancestors spent on digestion.
In that case, large teeth wouldn't be needed to maintain brain growth. Most people hate to hear that they have a slow metabolism, but it could help us live longer than most other animals. You see, the faster your metabolism, the more energy you need.
By using more energy the body will wear out or simply, die faster. Most apes eat fruits and leaves, eating meat only when they have no choice. Nuts, seeds, fish, insects and small animals were products ancestors started to eat. And these products provided building blocks that helped evolve our brain, and by doing so increase our intelligence. This resulted in the early human eventually creating advanced tools and using fire, which further increased our development.
It may sound funny to you, but our faces evolved to withstand punches. Of course, today most people stay away from fights, but before there were a lot more brutal battles between humans. Grade 6. Grade 7. Grade 8.

George Catlin was inspired to paint the sport after witnessing a game in Indian Territory in Games and Sports Games and sports appear to be universal features of human culture, both past and present. A boy playing ulama , a modern version of the Mesoamerican ballgame, in Sinaloa, Mexico. What defines a game versus a sport? A game of buzkashi in Mazar-e-Sharif, Afghanistan.
Sometimes in teams, buzkashi players fight to drag a goat or calf carcass to the goal. The study by Roberts, Arth, and Bush and those of a similar genre that followed indicated that: Men playing xiangqi, or Chinese chess, in Singapore Games of physical skill are cultural universals and are present in every society in which games are, or have been, reported.
Cross-cultural research Roberts and Sutton-Smith as well as Roberts and Barry shows that: Games of strategy are related to higher obedience training Games of chance are related to higher responsibility training, more anxiety over achievement and more severe sex training Games of physical skill are related to the higher rewards for achievement and greater frequency of achievement.
Boys playing a game of chess in Santiago de Cuba, Cuba Are sports related to warfare and other forms of aggression? Individual combative sports, team combative sports, and sham combat, predict some aspects of masculinist and hypermasculinist ideology and behavior.
Chick and Loy Sham combat is related to cultural ideologies valuing male aggressiveness and toughness, and to the view that women are inferior as well as to sexual violence toward women. Directions for Future Research Predictions regarding games based explicitly on biological evolutionary theory, in terms of natural and sexual selection, have only recently been applied to games and sports e.
Some new questions that might be explored with eHRAF World Cultures are: Other than sham combat being associated with warfare, do the games most prevalent in a society reflect the importance of other real world activities?

If the school approves, you can also place these on hallway walls on both sides of your classroom.
Instructions: Working in groups, each group is assigned a different primitive human - boy, girl, man, woman - and role. Each timeline is for one period in their human's life. Groups may be assigned the same primitive human. Tell the kids all humans will be dressed. Time period: It's the Stone Age, during the late fall. The timeline must include time they got up, dressed in what, food, weapons, activities during the day, roles within the community, any fears and concerns their human primitive might have.
Tell them to include what kind of berries, what kind of animal s. Eras: Eras Scavenger Hunt using stations you set up around the classroom. C reate a scavenger hunt sheet of things for kids to find in the sites listed on their exploration sheet. Check the sites you selected a day or two before the assignment before you run off copies to hand the kids. Sites come and go. I set this to work by telling the kids they have to site the source for each scavenger find for verification.
They will need instruction on how to site sources. I use the backside of my scavenger hunt sheet with an example of how to site a source. I do not go over the backside with them. I do tell them it's there. Dig Activity Pack free download. The difference between artifacts and fossils. Sticks and Stones, prehistory technology - you might want to team teach this one with your science teacher.
It's also a great way to show the difference between fossils science and artifacts social studies , by pointing at the science teacher who bows when the kids shout "fossils", and the pointing at the social studies teacher who bows when the kids shout "artifacts". After or Before you complete your unit on early humans, you need a week or so for a mini-unit on archaeology with activities.
That's when you set up a dig. I like doing the archaeology before early humans. That way I can move from early humans to agricultural societies smoothly, starting with ancient Mesopotamia. But either works - before or after, but - for new teachers - you do want to include your archaeology unit towards the early part of the school year. Choose Your Own Adventure from over 70 different classroom activities and possible assignments. New Teachers : Easy desk arrangements for the classroom - I move my desks around all the time, depending upon the activities I'm doing that day.
