New+England's+prehistoric+past+by+Rebeca

Introduction: Hi, my name is Rebeca I’m from Amigos school and I’m proud to say that is a great school. I say that because like you know not every school has the chance to have all this extraordinary fieldtrips. Where you learn a lot.

Location: 26-Oxford street, Cambridge Massachusetts- museum of Harvard location. This museum of natural history was established in 1998 as the public face of three research museums: the museum of comparative zoology, the Harvard university herbaria, and the mineral logical and geological museum. For more information

I’m going to tell you one of our fieldtrip. This fieldtrip was about ‘[harvard.edu/about_the_museum/about_the_museum.html|New England’s prehistoric past] ’. We learn in different time of their lives. I can say this fieldtrip was an actual lad that taught us that way before we were born and before Humans existed, 400-600 million years ago there were different things.

1-	What is a fossil? [[A fossil is the remains or traces of any organism. An organism is any living thing. Like you can know fossils can give you a lot of information but do you know that it doesn’t give you a complete Picture of lived in the past. 2-	450-600: in this time or ages the environment was most with SALT water, warm, quiet water and it was shallow. This means that before there was more water than land. When time past that ocean slowly disappeared lands were forming.   3-	450-350: Granite-big crystals it cooling rate is slow   and it formed in underground. Basalt- small crystals it cooling rate is fast and it formed in surface. Do you know what caused the holes in pumice? The thing that caused that is gas in the lava. The rocks can change with the function of boundary transform. 4-	220-190: Have you seeing a mud transform into mudstone? Well I haven’t but I had learn how they transform mud used to be mud for a long time and then they transform. 5-	190: today- what caused the rocks to become sand? Some forces the caused rocks to become sand is erosion. What make this move across the state is wind, rain, and rivers. Over 20,000 feet tall, New England Mountains average only 3,000 feet today. What happened to over 15,000 feet of mountain? Well what had happened is that soil is falling.

That is great how earth can change in a second don’t you think. I think that more schools should have the opportunity to learn all this great stuff!
