They compare how point mutations and frameshift mutations have very different overall impacts on the final amino acid ]]> https://www.biologycorner.com/2018/02/17/dna-proteins-and-mutations/feed/ 0 Evolution: Fact, Fiction, or Opinion https://www.biologycorner.com/2018/02/11/evolution-fact-fiction-or-opinion/ https://www.biologycorner.com/2018/02/11/evolution-fact-fiction-or-opinion/#comments Sun, 11 Feb 2018 22:01:26 +0000 https://www.biologycorner.com/?p=6276 This lesson can be used to introduce evolution and establish what your students already understand (or misunderstand) about evolutionary theory.    Statements can be printed and cut into slips and students work in small groups to categorize each statement as either Fact, Fiction, or Opinion.    The included answer key has quick explanations as well as links to authoritative sources to explain the positions, sources from Berkeley’ Understanding Evolution and New Scientist. Evolution misconceptions are fairly common for beginning biology students.  For example, many think that evolution leads to greater complexity, or that natural selection is the only process that ]]> https://www.biologycorner.com/2018/02/11/evolution-fact-fiction-or-opinion/feed/ 2 Concept Map on Blood https://www.biologycorner.com/2018/02/03/concept-map-on-blood/ https://www.biologycorner.com/2018/02/03/concept-map-on-blood/#respond Sat, 03 Feb 2018 16:54:16 +0000 https://www.biologycorner.com/?p=6267 Students studying blood and the lymphatic students can get overwhelmed with the terminology used to describe blood and how blood is categorized.   This project is designed to help students organize these difficult terms by creating a large concept map which groups related ideas together and connects them to other ideas – a concept map!   Students use color, sketches, containers, and arrows to develop a creative project that will help them build a mental map of the blood and the lymphatic system. I usually give them some guidance at the beginning by suggesting they start with the erythrocytes, leukocytes, and thrombocytes ]]> https://www.biologycorner.com/2018/02/03/concept-map-on-blood/feed/ 0
