Germination Practical (RP 8). This practical was completed in 2 lessons. Students are required to collect data outside of lesson time. I’ve attached both lessons, mock data (lesson 2) and a sign in sheet so you can create your own groups and student rota. Good luck! Lesson 1: Demo provided, students set up their practical, three conditions were created; full light-by windowsill, partial light-underneath windowsill and darkness-cupboard. The remainder of the lesson was spent discussing how to collect data, the student rota was explained. Students also used this time to assign roles to one another. Opportunity to collect data at break/lunch over 7 days (excluding weekends). Lesson 2: Interpreting data, working out averages, plotting graph, biological drawings. Conclusion and evaluation of practical was given as homework. Overall, this practical was very easy to set up but very fiddly to organise. Students need to take active approach as this practical needs to be done over 7 consecutive days, ownership to students. Mustard seeds were quick to germinate but were very poor at demonstrating phototropism. I would probably use coriander seeds next time. Also in the dark condition shoots grew very long, this confused students as light was absent (due to Etiolation), to complex for GCSE students to comprehend. Spec ref: 5.4.1 Required practical: Investigate the effect of light or gravity on the growth of newly germinated seedlings. Record results as both length measurements and as careful, labelled biological drawings to show the effects.

This lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). I taught this lesson after the required germination practical. Includes: slide animations, embedded video and practice questions with mark scheme. This resource is for separates ONLY. *NOTE-using plant hormones-Higher tier only* AQA spec link: 5.4.1, 5.4.2 Relevant chapter: B11.9/10- AQA Biology third edition textbook-Page 176-179 *The new specification requires students to know the following; Plants produce hormones to coordinate and control growth and responses: to light, phototropism; and gravity, gravitropism (geotropism). Unequal distributions of auxin cause unequal growth rates in plant roots and shoots. Gibberellins are important in initiating seed germination. Ethene controls cell division and ripening of fruits. The mechanisms of how gibberellins and ethene work are not required. Students should be able to describe the effects of some plant hormones and the different ways people use them to control plant growth. Plant growth hormones are used in agriculture and horticulture. Auxins are used as: • as weed killers • as rooting powders • for promoting growth in tissue culture. Ethene is used in the food industry to control ripening of fruit during storage and transport. Gibberellins can be used to: • end seed dormancy • promote flowering • increase fruit size.

Infertility treatments lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded video, worksheet and practice questions with mark scheme. This resource is suitable for combined science students. *Note-For higher tier only* AQA spec link:5.3.6 Relevant chapter: B11.8-Infertility treatments . AQA Biology third edition textbook-Page 174-175. *The new specification requires students to know the following; Students should be able to explain the use of hormones in modern reproductive technologies to treat infertility. This includes giving FSH and LH in a ‘fertility drug’ to a woman. She may then become pregnant in the normal way. In Vitro Fertilisation (IVF) treatment: • IVF involves giving a mother FSH and LH to stimulate the maturation of several eggs. • The eggs are collected from the mother and fertilised by sperm from the father in the laboratory. • The fertilised eggs develop into embryos. • At the stage when they are tiny balls of cells, one or two embryos are inserted into the mother’s uterus (womb). Although fertility treatment gives a woman the chance to have a baby of her own: • it is very emotionally and physically stressful • the success rates are not high • it can lead to multiple births which are a risk to both the babies and the mother.

The artificial control of fertility (contraception) lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded video and practice questions (homework) with mark scheme. This resource is suitable for combined science students. AQA spec link:5.3.5 Relevant chapter: B11.7-The artificial control of fertility . AQA Biology third edition textbook-Page 172-173. *The new specification requires students to know the following; Students should be able to evaluate the different hormonal and non-hormonal methods of contraception. Fertility can be controlled by a variety of hormonal and non-hormonal methods of contraception. These include: • oral contraceptives that contain hormones to inhibit FSH production so that no eggs mature • injection, implant, or skin patch of slow release progesterone to inhibit the maturation and release of eggs for a number of months or years • barrier methods such as condoms and diaphragms which prevent the sperm reaching an egg • intrauterine devices which prevent the implantation of an embryo or release a hormone • spermicidal agents which kill or disable sperm • abstaining from intercourse when an egg may be in the oviduct • surgical methods of male and female sterilisation.

The human Kidney lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). This is a printer friendly resource it includes an: embedded video, slide animations and a mini exam question. As i taught this lesson in two parts it's only fair i upload the other presentation also (2 for the price of 1). **Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required.** AQA spec link: 5.3.3 Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 185-186 *The new specification requires students to know the following; Students should be able to describe the function of kidneys in maintaining the water balance of the body. The kidneys produce urine by filtration of the blood and selective reabsorption of useful substances such as glucose, some ions, And water. Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required. Students should be able to translate tables and bar charts of glucose, ions, and urea before and after filtration. Students should be able to describe the effect of ADH on the permeability of the kidney tubules. The water level in the body is controlled by the hormone ADH which acts on the kidney tubules. ADH is released by the pituitary gland when the blood is too concentrated and it causes more water to be reabsorbed back into the blood from the kidney tubules. This is controlled by negative feedback.

Removing waste products lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations and worksheet. AQA spec link: 5.3.3 Relevant chapter: B12.2-Removing waste products . ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 184-185 *The new specification requires students to know the following; Students should be able to explain the effect on cells of osmotic changes in body fluids. Water leaves the body via the lungs during exhalation. Water, ions, and urea are lost from the skin in sweat. There is no control over water, ion, or urea loss by the lungs or skin. Excess water, ions, and urea are removed via the kidneys in the urine. If body cells lose or gain too much water by osmosis they do not function efficiently. The digestion of proteins from the diet results in excess amino acids which need to be excreted safely. In the liver these amino acids are deaminated to form ammonia. Ammonia is toxic and so it is immediately converted to urea for safe excretion.

Thermoregulation lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). This is a printer friendly resource it includes an: embedded video, slide animations and a mini exam question. AQA spec link: 5.2.4 Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 182-183 *The new specification requires students to know the following; Body temperature is monitored andcontrolled by the thermoregulatory centre in the brain. The thermoregulatory centre contains receptors sensitive to the temperature of the blood. The skin contains temperature receptorsand sends nervous impulses to the thermoregulatory centre. If the body temperature is too high, blood vessels dilate (vasodilation) and sweat is produced from the sweat glands.Both these mechanisms cause a transfer of energy from the skin to the environment. If the body temperature is too low, blood vessels constrict (vasoconstriction), sweating stops, and skeletal muscles contract (shiver). Students should be able to explain how these mechanisms lower or raise body temperature in a given context.
