Award-Winning Private Physiology Tutoring in Aurora, CO

"This afternoon the student reviewed Unit 3, "Geologic History". Lesson 5 "Records in Rocks" continued to describe sedimentary layers, how they can be dated, and how they indicate past environments. An "unconformity" is a missing layer where there was no deposition or the layer has eroded away. He filled in workbook pages and recalled that a trace fossil is a print where the organism has decayed, a body fossil still shows animal or plant tissues. He scored 100% and 96% on verbal and multiple choice quizzes. Lesson 6 "Index Fossils and Paleoenvironments" was a difficult, advanced lesson on rock layers. He scored 66% on the quiz and will likely revisit this lesson in the future to gain mastery. Lesson 7 "A Geologic Time Line" was interesting as we employed the Internet to see pictures of different past epochs. He knows that a meteorite that left a crater in Mexico is how the dinosaurs died. He did not know that the billowing dust from the impact caused plants to die first, or that 70% of life on earth perished in this great extinction event. With a lot of independence, the student earned a 94% on the Unit 3 test of 18 questions. He reviewed Hutton's idea called "uniformitarianism," relative and absolute dating, types of rock, how rocks are formed and what the arrangement of rock layers can tell us. Having touched real minerals, rocks and fossils, the student has a very satisfactory understanding of concepts."

"The student and I worked on her two Chemistry homework assignments and her poetry analysis homework. For Chemistry, we covered the ideal gas laws, and used the laws to find moles and grams of certain identified substances. The student did very well with this material and seems to be understanding it, she just needs to practice more on her own so it will totally sink in. "
