Science 7/8 Update: Earthquake-resistant towers

Students in Science 7/8 are studying a comprehensive unit on plate tectonics.  They have started by learning about earthquakes, and how seismologists use earthquake waves to study the interior of the earth.  Currently, 7th & 8th graders are using real engineering techniques to build earthquake-resistant towers out of toothpicks.  The towers will be tested on an earthquake simulation table that models real earthquake waves.  Next, students will be creating an earth’s interior art project as part of our arts and science integration.  After the art project, students will be studying Pangaea and will piece together the continents as they appeared 200 million years ago using the same evidence used by real scientists.  This will immediately be followed by the processes of plate tectonics, i.e., continental drift, seafloor spreading, convection in the mantle, etc., to help explain how the continents could have moved from the Pangaea formation to their current positions.  Finally, the unit will conclude with the different types of plate boundaries and their affect on shaping the earth as we know it today.

Science 6 Update: Rocks, fossils, and earth’s history…

During the 1st term, students in Science 6 covered three units on scientific inquiry, chemistry, and density.  Now that we are in term 2, the 6th graders are diving into an in-depth unit on geologic history.  So far they have learned about rocks, minerals, and fossils, and how geologists use them to date the earth, such as index fossils and the law of superposition.  Students are currently investigating how the six types of fossils are formed and will be moving into relative and absolute dating techniques.  The conclusion of the unit will find students creating an earth’s history brochure, which is an artistic representation of earth’s major time periods including the life forms that existed during each period.
