We started the day with our warm up. We read the article listed below, "The $1 billion mission to reach the Earth's mantle." Next we reviewed the evidence we looked at in class the other day: animal fossils, plant fossils, climate change, rock samples, etc. Even after all the Wegener's evidence, people still didn't believe in Continental Drift. Since Wegener could not explain how the continents moved, he died with out getting any credit. Once they started mapping the bottom of the ocean floor, scientists located the mid ocean ridge which helped to explain the movement of the continents. Here are the notes that go on page 42 in your notebook... Evidence from the Sea Floor. Next, we did a little lab on Convection Currents on page 43. Convection currents happen in the mantle, and this circular movement helps push the continents. If we have time today, we will continue on page 44 on Plate Boundaries. If you open the file below you will have all the links.
Watch the following video on the deepest hole on Earth. 1.What layer of the Earth were scientists able to dig to? 2. What percent of the way did scientists dig to the center of the Earth? 3.What did we learn from the Russian’s drilling the Kola Superdeep Borehole ? 4.What are two reasons why scientists couldn't dig any further?
Warm up - Watch the following video on the Layers of the Earth. Next, we did a quick review of solid, liquids, and gases. We took a few notes on page 40 in our notebooks. The reason we are reviewing solids, liquids and gases is because we have a special lab today that we can only do today. It is top secret!! Here are the notes from for page 40.
Finally we finished up with a review of the vocabulary on page 39. Here are the notes we added to the vocabulary on page 39. If we have time, we will start taking look at the evidence that supports continental drift.
We are going to tackle a ton of objectives today. We are going to cover Layers of the Earth, continental drift, Pangaea and Alfred Wegener. To accomplish all this, we are going to use the following blendspace. Each mini assignment has directions listed. You will be using your Layers of the Earth flip books as well as page 39 in your notebook. Here is the blendspace link
*** Definitely, make sure you take a look at A Journey to the Center of the Earth, it is a very cool *** graphic of the Earth. Lastly, we took some notes on solid, liquids and gases (page 40)--- to prepare for our lab next week.
Use the starred sites for more information from the website. Definitely take a peak at the Journey to the Center of the Earth---pretty amazing to think how far down we haven't gone.
After our test, we did a little research on the 3 rock types. I understand that rock types and the rock cycle is not new to you, we will just spend this one day reviewing both. Using the any of the websites below to find the following pieces of information about each of the rock types.
Igneous Rock - make sure you identity the differences between extrusive and intrusive igneous rocks. http://geology.com/rocks/igneous-rocks.shtml http://www.sciencekids.co.nz/sciencefacts/earth/igneousrocks.html http://www.scienceforkidsclub.com/igneous-rock.html Sedimentary Rocks http://geology.com/rocks/sedimentary-rocks.shtml http://www.sciencekids.co.nz/sciencefacts/earth/sedimentaryrocks.html http://www.scienceforkidsclub.com/sedimentary-rocks.html Metamorphic Rocks http://geology.com/rocks/metamorphic-rocks.shtml http://www.scienceforkidsclub.com/metamorphic-rock.html http://www.sciencekids.co.nz/sciencefacts/earth/metamorphicrocks.html Please finish this up for homework so we can review the rock cycle next class.
Our warm up was a review of Law of Conservation of Mass. Remember, Mass cannot be created or destroyed, only changed into something new. Whatever you start with, you end with. If you star with 50 grams of reactants, you have to end with 50 grams of products. Next we went over last nights homework (balancing equations on page 33). Balancing equations will be included on the test next class. Most of you did a great job and caught on super fast. If you still need help, here is a video to help you out, or come see me Monday morning at 7:00am for some last minute tutoring. I will meet you up front at 7:00. Next, we did a KAHOOT review of Chemistry. Reminder---Your test will cover everything from the beginning of chemistry all the way to balancing equations. Next, we completed a review activity using Task Cards. The answer to the task cards will go on page 33 in your notebook.
Here is a copy of the entire table of contents if you did not copy it in class.
