Inventions make the world go around. These days we don't think about candles or cooking pots as technology but at one time these simple tools were the science of the time and undoubtedly all the rage and in high demand.
The earliest direct evidence of tool usage was discovered in the Great Rift Valley of Ethiopia. The tools found there date back to 2.5 million years ago.
The term technology developed as a process of discovery combined with evolution. Technology is the result of science and engineering and includes tools, machinery, procedures, crafts, systems and methods of organization that solve a problem or perform a specific function to help humans and some animal species to manipulate natural environments. Some primates and dolphin species are known to have developed simple tools and pass the knowledge to other members of their communities.
Chimpanzees have been recorded using tools for foraging for food. West African chimpanzees have been seen using stone hammers to crack nuts. Other primitive tools include leaf sponges and sticks for probing termite mounds.
The first human made implements were from available natural resources converted into simple tools primarily in the form of choppers or scrapers. Bones, antlers and wood tools were used to scrape animal hides, and the mineral flint was used to make spears and arrow heads. Rocks were used for pounding food items such as acorns into meal for cooking.
Science knowledge and critical thinking are very important skills for children to learn. These images represent just a teensy amount of these inventions designed to make our lives easier.
The common thread for creativity is education, access and opportunity, not race or ethnicity.
Inventions are often spurred by necessity. The fingernal clipper, screw driver, hammer, gas gauge, hair brush, door knob, are all inventions to help people groom ourselves and build houses and drive cars and trucks.

Paper Trivia: Did you know that you can only fold a sheet of printer paper in half seven times? Give it a try. It doesn't matter how thick or thin the paper is, once you get to the seventh fold, the paper will not bend or budge.
Sun catchers. To create a translucent, stained glass ornaments effect, apply a bit of lemon oil to the back sides of paper ornaments to create a.
Hang the ornaments on trees, in windows, anywhere bright colorful decorations are desired.
Construct a large paper-tree for the wall with shades of green construction paper. Draw a large tree on a sheet of easel pad paper to tack onto a wall or other flat surface, then decorate with paper ornaments.
