What We Learned in 7th Grade Science By acybay Sep 1, 2009 First Week of School What is Science? Period: Sep 1, 2009 to Nov 30, 2010 Diversity of Life Study of Organisms both multicellular and unicellular, Plants and Animals, Cells, and Human Body Systems Sep 5, 2009 Plants and Animals multicellular vs. unicellular herbivores, carnivores, and omnivores heterotrophs vs. autotrophs Oct 12, 2009 Field Trip to the Baltimore Zoo After studying plants and animals, we visited the Baltimore Zoo to take a closer look at a variety of organisms from around the world, both plant and animal. Nov 22, 2009 Science Center and Imax Field Trip Visited the Science Center and viewed and Imax film on the systems of the human body. Period: Dec 1, 2009 to Jan 31, 2010 Change Over Time Study of genetics and how organisms have evolved and adapted over time. Dec 4, 2009 Genetic Tree We examined various physical features and plotted the results on a classroom tree. We were able to see which genetic traits were more common or dominant and which were recessive. Period: Feb 1, 2010 to Apr 15, 2010 Sound and Light Waves Study of the types of waves, characteristics of waves and how waves react in various mediums. Mar 20, 2010 Bending Light Used mirrors to bend and reflect light to hit a specific mark. Studied the Law of Reflection. Apr 8, 2010 Sound Waves Measured the frequency and pitch of waves and how amplitude is affected using Lab Pro and tuning forks. Period: Apr 16, 2010 to Jun 9, 2010 Digging Into Earth's Past Study of types of rocks, rock characteristics, rock cycle, types of fossils, fossil formation, relative and absolute age, and the Law of Superposition. May 3, 2010 Volcanic Eruption Studied the formation of igneous rocks and began with a demonstration of extrusive versus intrusive rocks through an eruption of a model volcano. May 27, 2010 Creating Fossils Created a model of sedimentary rock with a mold fossil out of plaster of paris, sand, water, and a model of a cast fossil.
