Unit 2-Practical scientific procedures and techniques Learning aim D: Review personal development of scientific skills for laboratory work. How did i teach this? This assignment allows students to review the skills they attained in this unit. It also reiterates the importance of H&S as well as professional practice. Before setting the assignment i first taught three lessons covering the content in Pearson BTEC national-Applied science-Student book 1. Due to the complexity of this assignment i provided my students with a template which covered the P/M/D criteria (download the free template). This prevented students from going off on a tangent and also ensured they had mentioned the key skills for both assignment B and C. NB: Interpersonal skills is the second lesson of the three lessons. Worksheets attached and videos embedded for ease of use.

Types of reproduction lesson created in accordance to the NEW AQA Specification (9-1). Designed for a TRILOGY 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. AQA spec link: 6.1.1 Relevant chapter: B12 Genetics and reproduction. AQA Biology third edition textbook-Page 162-163. Specification requires students to know the following; Students should understand that meiosis leads to non-identical cells being formed while mitosis leads to identical cells being formed. Sexual reproduction involves the joining (fusion) of male and female gametes: • sperm and egg cells in animals • pollen and egg cells in flowering plants. In sexual reproduction there is mixing of genetic information which leads to variety in the offspring. The formation of gametes involves meiosis. Asexual reproduction involves only one parent and no fusion of gametes. There is no mixing of genetic information. This leads to genetically identical offspring (clones). Only mitosis is involved. Good luck with your lesson!

Eukaryotic and prokaryotic cells lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability class, although content can be adjusted to suit any ability. Includes: slide animations, embedded videos and practice questions with answers on slides. AQA spec link: 1.1.1 Relevant chapter: B1 Cell structure and transport. AQA Biology third edition textbook-Page 8-9 Specification requires students to know the following; Plant and animal cells (eukaryotic cells) have a cell membrane, cytoplasm and genetic material enclosed in a nucleus. Bacterial cells (prokaryotic cells) are much smaller in comparison. They have cytoplasm and a cell membrane surrounded by a cell wall. The genetic material is not enclosed in a nucleus. It is a single DNA loop and there may be one or more small rings of DNA called plasmids. Students should be able to demonstrate an understanding of the scale and size of cells and be able to make order of magnitude calculations, including the use of standard form. MS 1b, 2a, 2h WS 4.4 Use prefixes centi, milli, micro and nano.

Cell division in sexual reproduction, otherwise known as meiosis lesson created in accordance to the NEW AQA Specification (9-1). Designed for a trilogy class, although content can be adjusted to suit any ability. Includes: slide animations, embedded timers, practice questions with answers on slides, quiz and 6 mark past paper question with ms. *Knowledge of the stages of meiosis is not required.* AQA spec link: 6.1.1 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 198-199. Specification requires students to know the following; 6.1.2 Students should be able to explain how meiosis halves the number of chromosomes in gametes and fertilisation restores the full number of chromosomes. Cells in reproductive organs divide by meiosis to form gametes. When a cell divides to form gametes: • copies of the genetic information are made • the cell divides twice to form four gametes, each with a single set of chromosomes • all gametes are genetically different from each other. Gametes join at fertilisation to restore the normal number of chromosomes. The new cell divides by mitosis. The number of cells increases. As the embryo develops cells differentiate.

Investigate the effect of pH on the rate of reaction (RP 5-separate science). This practical was completed in one lesson, students were asked to construct a graph from their data for homework. How did i deliver this practical? I used 5 different buffered pH solutions (4,5,6,7,8). I split my class into two groups ( 2 x 15). Within each group there were 5 sub-groups. This allowed me to gather two sets of results for each pH. Group A Group B | Student group 1-pH 4 | Student group 1-pH 4 | Student group 2-pH 5 | Student group 2-pH 5 | Student group 3-pH 6 | Student group 3-pH 6 | Student group 4-pH 7 | Student group 4-pH 7 | Student group 5-pH 8 | Student group 5-pH 8 AQA spec link: 4.2.2.1 Relevant chapter: B3 Organisation and the digestive system. AQA Biology third edition textbook-Page 46-47 Students are required to know the following; Required practical activity 5: investigate the effect of pH on the rate of reaction of amylase enzyme. Students should use a continuous sampling technique to determine the time taken to completely digest a starch solution at a range of pH values. Iodine reagent is to be used to test for starch every 30 seconds. Temperature must be controlled by use of a water bath or electric heater. AT skills covered by this practical activity: AT 1, 2, 5 and 8. This practical activity also provides opportunities to develop WS and MS. Details of all skills are given in Key opportunities for skills development.

B10 and B11 revision pack created for biology separates. It includes a series of practice paper questions and a mark scheme, I've tried to include a question from each topic. Total marks out of 33. Perfect to set over the half term, or for a quick progress check at the end of the topic (formative assessment).

I have designed a set of past paper questions for the plant hormones and responses topic, total marks /21. A marking grid has also been included. Contains a range of short and longer answer questions also requires students to interpret diagrams. This is a great piece of homework or mini class test, that can allow you to determine whether your students have understood the topic. I’ve attached the mark scheme separately as it’s a great self/peer-assessed activity (reduce the marking load).

AQA A-Level New specification-The cell cycle-Cells 3.8 (3.2.2) Includes: questions, embedded videos, slide timers, slide animations, interactive answers on slides, and a plenary. Also includes a mini topic test, with markscheme. AQA Specification reference: 3.2.2 ALevel Biology Textbook: Section 2 Cells, Chapter 3.8

Dont’t know if you’ve felt the same but my year 11 students really struggled to grasp punnett squares through a couple of worked examples so I designed a booklet solely focused on punnett square PPQ’s with some very challenging questions. As always total marks /21, not too short or too long to take up an entire lesson. A marking grid has also been included. Contains a range of short and longer answer questions also requires students to interpret diagrams. This is a great piece of homework or mini class test, that can allow you to determine whether your students have understood the topic. I’ve attached the mark scheme separately as it’s a great self/peer-assessed activity (reduce the marking load).

Complete lesson Includes: embedded videos, slide timers, slide animations, interactive answers on slides, and a plenary 3.2.1.1 In complex multicellular organisms, eukaryotic cells become specialised for specific functions. Specialised cells are organised into tissues, tissues into organs and organs into systems.

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.
