Based on what I have learned, and in my reading of the unit texts, the changes to the New World because of Christopher Columbus’ arrival were both positive and negative. Columbus and the European arrival in the New World also had a hugely profound impact on the Americas. Disease would destroy native cultures, and change the landscape. Technology and goods that were a result of the Columbian Exchange would transform the lives of Native Americans in a positive way. This technology as well as disease would have a negative impact on the landscape, including the animal population of the Americas. Paragraph 2, Columbus’ goal, opinion of the natives

Paragraph 3, Columbus and European interaction with the natives

Paragraph 4, positive impacts of Columbian Exchange FOOD and GOODS

Paragraph 5, positive impacts of Columbian Exchange TECHNOLOGY

Paragraph 6, negative impact on natives due to Columbus and European arrival

Paragraph 7, negative effects on the landscape of the Americas

Paragraph 8, CONCLUSION

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
