We are continuing to learn about evolution, focusing on geologic, climatic, and technological aspects. We will learn about ice cores on Monday and how ash and various gas isotopes are trapped to reveal evidence about recent and ancient climates. On Tuesday we will examine evidence of Continental Drift: that plates are in constant motion churned by convection currents in magma underneath the lithosphere. Students will do a student inquiry to fit together continents with matching evidence. Thursday and Friday we will discuss and go through various activities on remote sensing. Remote sensing uses electromagnetic radiation both actively and passively. We will first learn about the electromagnetic spectrum, its various wavelengths, spectral signatures of various objects (including absorption, transmission, reflection of wavelengths), and its applications in society (radar, satellites, weather forecasting, GPS, cell phones, etc). *Please keep in mind that we will have a chapter test next Thursday December 15th. Students will need to review daily, especially remote sensing, so as not to cram for Science the night before. We will probably have more than one test on this day because of Christmas break.
Homework:
Monday night: questions about ice cores
Tuesday night: mapping/webbing of Continental Drift and its Geologic Evidence (pg. 419-426)
Wednesday night: questions pg. 427 all
Thursday night: study guide definitions second column pg. 443 (mid-Atlantic ridge to deforestation) and pg. 438 all
