Allopatric & Sympatric Speciation

Allopatric & Sympatric Speciation

Loaded as part of a Lesson. Feel free to alter the Power Point as required to suit you. I get the pupils to describe what they see and then link the keyword to this. A mind map is provided for reinforcement/development - encourage pupils to find or add their own words when writing this up. A slide with useful words is provided on the Power Point and this can be displayed when pupils are completing their mind maps. Loaded onto 'My Lessons' - https://www.tes.com/my-resources/lessons/eZqSMkj4vnz-9g Unfortunately, flash game won't load properly onto this platform. A Mix and Match game has been added as a plenary.

AQA new specification-Screening genetic disorders-B13.10

AQA new specification-Screening genetic disorders-B13.10

Screening for genetic disorders lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability TRILOGY(combined science) class, although content can be adjusted to suit any ability. Includes: slide animations, embedded videos and practice questions with answers on slides as well as a quiz. This video contains many videos and is a great lesson to spark a debate. I'd appreciate a review after your lesson :) AQA spec link: 6.1.7 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 214-215. Some disorders are inherited. These disorders are caused by the inheritance of certain alleles. • Polydactyly (having extra fingers or toes) is caused by a dominant allele. • Cystic fibrosis (a disorder of cell membranes) is caused by a recessive allele. Students should make informed judgements about the economic, social and ethical issues concerning embryo screening, given appropriate information. WS 1.3 Appreciate that embryo screening and gene therapy may alleviate suffering but consider the ethical issues which arise.

AQA new specification-Inherited disorders-B13.9

Inherited disorders lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides and an interactive quiz. Included a set of past paper questions, with level 1-3 demand questions, this is an excellent way of reviewing the lesson and differentiating within the classroom. Mark scheme has also been attached separately. AQA spec link: 6.1.7 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 212-213. Students are required to know the following; Some disorders are inherited. These disorders are caused by the inheritance of certain alleles. • Polydactyly (having extra fingers or toes) is caused by a dominant allele. • Cystic fibrosis (a disorder of cell membranes) is caused by a recessive allele.

AQA new specification-More about genetics-B13.8

AQA new specification-More about genetics-B13.8

More about genetics lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides and an interactive quiz. AQA spec link: 6.1.8 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 210-211. Students are required to know the following; Ordinary human body cells contain 23 pairs of chromosomes. 22 pairs control characteristics only, but one of the pairs carries the genes that determine sex. • In females the sex chromosomes are the same (XX). • In males the chromosomes are different (XY). Students should be able to carry out a genetic cross to show sex inheritance. Students should understand and use direct proportion and simple ratios in genetic crosses.

AQA new specification-Inheritance in action-B13.7

AQA new specification-Inheritance in action-B13.7

Inheritance in action lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides and an interactive quiz. AQA spec link: 6.1.6 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 208-209. Students should be able to explain the terms: • gamete • chromosome • gene • allele • dominant • recessive • homozygous • heterozygous • genotype • phenotype. Some characteristics are controlled by a single gene, such as: fur colour in mice; and red-green colour blindness in humans. Each gene may have different forms called alleles. The alleles present, or genotype, operate at a molecular level to develop characteristics that can be expressed as a phenotype. A dominant allele is always expressed, even if only one copy is present. A recessive allele is only expressed if two copies are present (therefore no dominant allele present). If the two alleles present are the same the organism is homozygous for that trait, but if the alleles are different they are heterozygous. Most characteristics are a result of multiple genes interacting, rather than a single gene. Students should be able to understand the concept of probability in predicting the results of a single gene cross, but recall that most phenotype features are the result of multiple genes rather than single gene inheritance. MS 2e Students should be able to use direct proportion and simple ratios to express the outcome of a genetic cross. MS 1c, 3a Students should be able to complete a Punnett square diagram and extract and interpret information from genetic crosses and family trees. MS 2c, 4a (HT only) Students should be able to construct a genetic cross by Punnett square diagram and use it to make predictions using the theory of probability.

Human Evolution Reading - The Fossil Record and Extinction

Human Evolution Reading - The Fossil Record and Extinction

RocketLit articles are all written at 7 reading levels. Our writing is analogy driven and focuses on giving students a conceptual basis of understanding This article explicitly defines the following terms: fossil record, bipedalism, extinction, diversity This activity gives students an introduction to the history of the modern human. The article talks about how the fossil record allows us to see the diversity of early humans, their eventual extinction, and the development of bipedalism.
