M.L.K. weekend... No School :)
Tuesday or January 19, 2016 C.E.:
Today we came back from a three-day weekend to start a new unit. It is Unit 6 which goes into detail about Weathering and Erosion which is something we covered in the past unit as well. We took notes about the first section. It talked about the two types of weathering. The first is mechanical and the second is chemical. Mechanical happens by scraping and other mechanical things. Chemical weathering changes the chemical composition of the material it is weathering. One example of Mechanical weathering is rock scraping on another rock. An example of chemical weathering is the rusting of iron in rock causing them to crumble. We also did a cool skittles lab today. We each took a skittle and dropped water on them with a pipette.We saw how the water shaped the skittle and how the runoff was colored. It was quite a cool lab.

Today we started a Weathering and Erosion lab. It has seven stations and each one represents a type of weathering. It was really cool. Today I did the first four stations. The stations included frost action which is the freezing and expanding of ice and carbonation, a chemical reaction. It was cool to see erosion hands on. Tomorrow I will do sections 5, 6, and 7. They are about water's erosion and abrasion (scraping) among other things. I can't wait to keep doing this lab.

Today I did the last three sections of the lab. I had to make a description of a picture of natural eroded coastline. I also had to explain how it formed. On it were cliffs and caves, but my favorite phenomenon is the cliff blow hole. Water is pressed into the cliff over time. Eventually the water bores a hole through the cliff all the way to the top. It then spews out the top of the cliff in a "blowhole". It is really cool and I have always wanted to see one in real life. We finished our labs and turned them in today.

Today we worked a little more on another lab. It is the Seeds to Shoreline project in which we cultivate marsh grass in class and replant it in wetlands. Since the 15th we have been waiting for our seeds to germinate. Today we counted and we had 2 germinated seeds. We also made a cover page for our lab. It has a drawing of Spartina Alterniflora, the name of the grass and a wetland on it. We wanted to make the cover page nice looking. In the coming weeks we will see how the seeds germinate and grow. It will be a cool multi-month lab.
Summary: This week was good. We came back from our 3-day weekend refreshed and ready to learn. We learned more about weathering and erosion from our new unit and we took part in interesting labs. I need to work on finishing my blog swifter, like always and I need to work faster in general.
