Week of January 19th
Last Tuesday we focused on rocks throughout the week. On Tuesday we watched the inauguration. Then on Wednesday our teacher gave us different rocks. My group and came up with ideas on some of the rock. Eventually on Thursday we defined all the rocks. But on Friday I got sick and missed the work. I will go in during study hall to get the work i missed.

Week of January 19th
On Monday we began learning about the Law of Superposition and how to find which is the oldest to newest rock. There are pictures with descriptions on the HEATING link on my my page. The next day our teacher had us observe some rocks. We ended up finding out that the rocks were igneous. The were ridged, grey , shiny , and had a crystal in the side. Then the second rock had many holes. This rock was igneous too. The difference was that the first had a long time to cool and the second had a short time. We then did an experiment to see if we were right and we were right. The one from the experiment that had little time to cool was thin and had holes with small crystals, the one with a long time to cool was one huge crystal. On Friday we started a work sheet and didn't finish.
***We also worked on answering our study guide which i did. I had some questions. Here they are:
1. How do you calculate spreading of sea floor rate.
2.What was the fearless video, i thin i was absent that day, what was it on.
3.Riffle zone??? is that a Rift Valley???

Week of January 11
This week in science we learned a lot of new things which I found very interesting. We started off on Monday talking about heating not heat because heat is not a thing. We talked about the three different types of heating:
Radiation: transferring through space/air
Conduction: heating through touching
Convection: heating by movement of fluids
The next day we talked about the uses for gloves and we saw how they worked. They kept your hands warm and also protect them from heat. Mr. Finley drew two models on the board. The pictures are on the link on my blog called HEATING. The next day we went over how particles move when heated and how a lava lamp works. We also looked at how the lava lamp relates to how plates move. To see how the plates move click on the HEATING link. Then we saw how you can tell which rock is the oldest and which is the newest. You can tell by a volcano which is the newest because when it erupts the lava dries up on top of the previous rock and this happens over and over again. It is the law of Superposition.
