• Unit 4 Review Package and Answer Key

  • Review Activity: https://sepup.lawrencehallofscience.org/geology-unit-plate-boundaries/

    • • Pick an option (type of plate boundary)

        • Pick a time (start with a long time period)

        • Click "Run"

        • Observe what happens and figure out why

      • Click on "Home" to try out a different type of plate boundary

      • Try out all five types

Bonus Activities

• • Plate Tectonics Activity: https://phet.colorado.edu/en/simulations/plate-tectonics

    • • • click on the button to download the animation

        • Go into your downloads folder, and click on the file (plate-tectonics_en.jar)

          • • • this should work on the Room 200 computers, it may or not work on other computers

        • The Crust tab lets you see what variables cause tectonic plates to be oceanic or continental

        • The Plate Motion tab lets you see how the different types of crust interact

          • • • Drag one type of crust to the left

              • Drag another type of crust to the right

              • Play around with the different options to see how it works

    • Radioactive Dating Game (tricky): https://phet.colorado.edu/sims/cheerpj/nuclear-physics/latest/nuclear-physics.html?simulation=radioactive-dating-game

      • • • • Click on the link above, it may take a while to load

            • To start

              • • Half Life: Select Carbon 14

                • Decay Rates:  You can see that after a bit less than 6000 years, half of the Carbon 14 that the organism had in it's body when it died will have decayed to Nitrogen 14

                • Measurement: Choose Tree

                • Click "Plant Tree"

                • Click "Kill Tree"

                • Watch what happens to the percentage of Carbon 14 in the dead tree over time (object).

                • Compare that to what happens with the percentage of Carbon 14 in the atmosphere over time (air)

            • Play around with Uranium-238 levels to figure out how that can be used to measure the age of objects

            • Try out the Dating Game

              • • hint: sometimes you'll need to use custom probes
