This lesson provides students with the opportunity to analyse the relationship two variables and how biotic and abiotic factors affect distribution and abundance of species. Fill worked examples of Pearson’s Linear Correlation included.

The lesson starts with identifying and describing the terms ‘ecosystem’ and ‘niche’ and then how the different levels that biodiversity can be assessed at. The lesson concludes with an explanation of the importance of random sampling, suitable random sampling methods and use the Lincoln Index. Full worked examples included.

This lesson starts with a review the meaning of the term ‘species’ and then students learn of the three domains: Archaea, Bacteria and Eukarya. The lesson progresses to look at the characteristics of the four Eukarya Kingdoms, finishing off with an outline how viruses are classified.

This lesson starts with a recall of the structure of phloem tubes and their companion cells. Students then learn of the process of translocation from source to sink. Finally, the lesson covers why some parts of the plant may be a source and sink at different times of the year. Fully resourced, exam questions included.

In this lesson, students learn about transpiration in terms of water potential how water moves from the soil through a plant and into the air. They learn of the three pathways by which water is transported from soil to xylem and the three mechanisms by which water is moved from roots to leaves. Exam questions included.

This first lesson starts with a recall from KS4 of the outline of the structures and roles of phloem and xylem. The lesson then progresses on to describe their distribution in roots, stems and leaves. The second lesson progresses onto identification of the vascular bundles on micrographs, to look at the structures of the xylem and phloem in detail and describe their internal structures to their function. The lesson concludes with an overview of the role of companion cells.

This lesson starts with a recall of what a ‘gene mutation’ is before moving on to learn how gene mutations occur. Lesson concludes with an explaination on how mutations affects the formation of the polypeptide.

In this lesson students recall the process of mitosis and learn how it works. Students then learn how meiosis results in the formation of haploid cells. The lesson then progresses to explain how mitosis and meiosis are used in the formation of an embryo. Fully resourced. Exam questions included.

This lesson starts with the different types of proteins that DNA codes for and how chromosomes are used to make proteins - transcription and translation. The lesson concludes with why not all genes are expressed at the same time. Fully resourced with videos and exam questions.

In this lesson, students learn about the role of chromosomes and the relationship between chromosomes, genes and DNA. They then learn of differences between genes and alleles. Differences between the X and Y chromosomes are learnt and how gender is inherited. Lesson concludes with a brief overview how genes code for proteins. (Transcription and Translation comes in another lesson). Fully resourced with videos and exam questions.

In this lesson students learn what an STI is with reference to what HIV is and describe how HIV can lead to AIDS. Students learn how HIV is transmitted and how transmission of STI’s can be controlled (B). Fully resourced with exam questions.

In this lesson, students learn about the stages of the menstrual cycle and the changes in the uterus and ovaries during the menstrual cycle. For higher tier students, they also learn of the role of hormones FSH, LH, progesterone and oestrogen in controlling the menstrual cycle. Lots of resources, activities and exam questions.

in this lesson the students learn about what happens to the zygote after fertilisation. They then learn about the role of the placenta, umbilical cord, amniotic sac and fluid, and how nutrients and waste products are exchanged between mother and fetus (B). Fully resourced with exam questions.

In this lesson, students identify the reproductive organs and describe their roles in fertilisation. They then progress to describe and explain the features of the gametes, finishing with outlining stages of fertilisation and the formation of a zygote. Videos and exam questions included.

This lesson covers the conditions needed for seed growth and provides the opportunity for an investigation into these conditions. Exam questions for the whole plant topic included.

This lesson starts with a recall of the differences between cross pollination and self-pollination and then the process of fertilisation. The lesson then covers the effects of cross and self-pollination. Fully resourced.

This lesson identifies and describes the functions of the reproductive organs of insect and wind pollinated flowers. Students then identify differences between wind and insect pollinated flowers and distinguishes between two different types of pollen grain and describes the process of pollination. The lesson then progresses to look at the differences between cross pollination and self-pollination. Fully resourced.

This lesson starts with KS3 recall of the similarities and differences between asexual and sexual reproduction. It progresses to describe the advantages and disadvantages for both types and how some organisms can reproduce using both methods. The lesson uses a YouTube video link for students to summarise into bullet notes. The transcript is also provided for EAL learners.

This lesson starts with a review of different classes of drugs and thenwhat antibiotics are used for. The lesson then explains how they work with an analysis of how antibiotic resistance can occur and how we can stop the spread of antibiotic resistance. Fully resources with videos and exam questions.

This lesson starts with recall the structure of proteins and the structure of a gene then to explain how genes code for the amino acids in a polypeptide. The lesson finishes off with principle of the universal genetic code.
