This PowerPoint relates to the Properties of Water section of the BY1 specification. Students learn about the: Importance of water in terms of its polarity, ability to form hydrogen bonds, surface tension, as a solvent, thermal properties, as a metabolite.

This PowerPoint relates to the Plasma Membranes section of the BY1 specification. Students learn about the: (a) Principal components of the plasma membrane and the fluid mosaic model. Factors affecting permeability of the membrane. (b) Transport mechanisms: diffusion and factors affecting the rate of diffusion, osmosis and water potential, pinocytosis, facilitated diffusion, phagocytosis, secretion (exocytosis), active transport and influence of cyanide.

This is a series of PowerPoint presentations, produced for students to aid their understanding of topics encountered throughout the biochemistry component of the AS Biology course. It is also a useful revision tool for student when used with the guidance notes. (WJEC)

This PowerPoint relates to the Inhibitors section of the BY1 specification. Students learn about the: Principles of competitive and non competitive inhibition (references to reversible and irreversible action not required).

This PowerPoint relates to the Cell Membranes and Transport section of the BY1 specification. Students learn about the: Principal components of the plasma membrane and the fluid mosaic model. Factors affecting permeability of the membrane.

This PowerPoint relates to the Immobilised Enzymes section of the BY1 specification. Students learn about the: Determination of water potential by measuring changes in mass, and solute potential by measuring the degree of incipient plasmolysis. The permeability of cell membranes using beetroot.

A series of resources including video, animation and whiteboard materials that address the skills, knowledge within the GCSE specifications. This unit helps pupils to understand that at each stage in the food chain energy is lost in waste materials, in repair and maintenance of cells and as heat during respiration. The activities include interpreting the effects of eating from different trophic levels in a food chain and comparisons of vegetarian and meat diets and eating from different trophic levels.

A series of resources including video, animation and whiteboard materials that address the skills, knowledge and understanding of how science works within the GCSE specifications. The unit requires pupils to explore information about the causes of the destruction of habitat and reduced biodiversity including the effects of pollution on the river environment. Examples show how invertebrates can be used to determine pollution levels and how the levels of nitrate/oxygen in water samples can affect organisms.

A series of resources including video, animation and whiteboard materials that address the skills, knowledge and understanding of how science works within the GCSE specifications. The resources discuss the advantages and drawbacks of intensive farming methods, such as using fertilisers, pesticides, disease control and battery methods to increase yields.

The scheme of work includes thinking skills activities and covers the following areas: Drugs Introduction Caffeine Insulin Paracetemol Steroids Addiction

6 interactive activities to support WJEC Biology 1, that can be used on a whiteboard with a whole class, or for individual study/revision. Topics include: * competition/adaptation, * inheritance * temperature regulation * natural selection.

This PowerPoint presentation brings together all the learning outcomes of Biochemistry units in the BY1 specification for the Biology and Human Biology AS courses. The relevant section of the Teacher’s Guidance material follows, together with some explanatory notes.

A series of resources including video, animation and whiteboard materials that address the skills, knowledge and understanding of how science works within the GCSE specifications. Using data from data from ICT and food labelling pupils are encouraged to explore and discuss energy and additives in highly processed and less processed foods, and the implications, particularly for health.

The Flipcharts included in this activity deal with DNA, genes, Mendel and genetic problems, cystic fibrosis, deciding the sex, genetic engineering and variation.
