Use clues to put Pangaea pieces together into a super continent.
First, we practiced plate movement diagrams and finished notes on transform plate boundaries. Find and color-code the 7 major plates. Notice the type of boundary where the large plates meet. Are the boundaries convergent, divergent or transform? We also took down some extra notes. ![]()
Convection observation and notes What parts of Earth's interior make up a plate? crust and upper mantle (solid) What is underneath the plates? plasticlike asthenosphere What is causing the plates to move? convection Mark plate, lithosphere, asthenosphere and convection on Earth's interior model. Afterward, observe Mountain Maker, Earth Shaker Interactive and record observations on handout. ![]()

Practice making models... Density, pressure and temperature trends with evidence What travels through Earth and can tell us about its inside? earthquake waves Demonstration: P and S body waves in wrestling room After demonstration, we sketched and wrote down information about P and S waves. We figured-out trends for p and s waves traveling through the Earth: When P waves travel through the earth's inside (interior) then... When S waves travel through the earth's inside (interior) then... and then taped in handout showing these trends into our notebook. Continue writing trends from yesterday...
Why do we make models in science? Trying to study or look at something to big or to small In our case, the earth is to big to study without making a model of it. So we need to scale it down... Crust = 0-22 miles Mantle = 22-1790 miles Outer Core = 1790-3160 miles Inner Core = 3160-3954 miles How do you make a scale model?... want to make a model of Earth's interior 1) How big is the model? 3954 miles - 0 miles = 3954 miles 2) How much space to you have? find center of paper and measure to side with shortest distance (~10 cm) 3) Scale = how many miles in each centimeter 4) Use scale to make each measurement listed smaller. 5) Mark these measurements and use compass to make circles to model Earth's interior. ![]()
To start class, we worked through some models of Earth's interior to brainstorm ideas about what we know or can figure-out about the inside of Earth is like. Read "What's the Story" on page 223-224. What don't we know about the earth's inside? What questions about the earth's interior would you want answered if you could take a robotic device to the core? ![]()
