It's Tool Tifflie

ARCHAEOLOGISTS USE the discovery of tools to identify and learn more about specific cultures. Tools serve many purposes in all cultures. Today you might use a hammer, but long ago people hammered with rocks. Today you use a needle and thread to sew, but people once created sewing needles out of bone and thread from the sinew of animals. From the earliest days, tools have been used for hunting, skinning, cutting, and cooking. People look at a need and create a tool to help them with that need.

Now it’s time to build your own tool. Have you ever tried to reach for something that is too high? Sure, you can climb on top of a chair, but that means having to move it or worry about falling off the chair. What if you could make a tool to grab what you need?

Materials

?  Rope, half the width of your tube but three times as long

?  Pencil or knitting needle

?  Long plastic tube, at least as long as your arm

Make a slipknot in the middle of the rope. First, create a loop in the middle of the rope. Wrap one end of the rope around the loop, and then create another loop that you pull through the first loop.

If tied correctly, one end of your rope will tighten the knot, and other will undo it. You might want to mark the end that will tighten it with a piece of tape or by tying another knot in the end of it.

Put a pencil or knitting needle through the loop and tighten the knot around it. This will help you pull the slipknot through the plastic tube without it coming undone.

After you’ve pulled your knot through the tube, make the knot bigger again and remove the pencil or knitting needle. When you need to retrieve something (nonbreakable only), use the tube of your tool to place the loop of rope around the object. Then pull the knot tight with the correct end of your rope. This should secure your object while you bring it down.

Oceanian, and African groups tested. From these results, scientists suggest that the earliest Native Americans must have been isolated from these other populations for thousands of years.

Some Native Americans question why scientists claim that their ancestors must have come across a land bridge or from somewhere else by boat. They asked, why couldn’t Native Americans have always been present in North America? The varied information uncovered by archaeologists and anthropologists can’t rule that out. Indeed, research suggests that a variety of migrations from different areas took place at different times. Yet it’s not just the origins of Native Americans that are being sought, but the origins of human life.

Learning more about the origins of Native Americans is an ongoing project, requiring the joint efforts of archaeologists, linguists, and biologists. New discoveries are constantly being made. Some of them may replace today’s theories.
