Students always need practice in number system conversion. This resource gives them instant feedback and allows them to progress from conversion to binary addition. This would make an ideal homework activity. the file is a macro enabled worksheet and can be downloaded from the zip file.

The workbook contains a number of simulations designed to aid students understanding of the Binomial distribution.

Binomial distribution: simulated tossing a coin ten times. The probability of achieving 0,1,2… heads is calculated and displayed in a frequency table and a bar chart. The...

Most binomial questions define the binomial distribution and ask students to calculate the most likely value for x. In this activity, students are asked to explore whether the value for p can be found given the value for n and the most likely value for x. Subsequent pages of the presentation provide the solution to...

In this activity, students apply their knowledge of the binomial distribution to establish whether each of three rules, regarding the most likely outcome and the expected value, are true. The presentation contains a link to an applet which allows experimentation, and shows the binomial probabilities for various n...

This activity begins with the definition of the mean and the variance of a binomial distribution. Students are then challenged to take each definition and prove that they work for the binomial distribution B(3,p). The first task is for students to construct the probability distribution then calculate the mean and...

This Biochemical Society careers resource is aimed at students and provides an overview of the impact of biochemistry on other areas of science, a description of what biochemistry is and an illustration of the range of organisations which employ biochemists.

There is also a description of the types of...

This colourful leaflet from the Natural Environment Research Council (NERC) looks at what biodiversity is and why it matters. It also explains how human activities threaten the natural environment, endangering species and habitats and what we are doing about the problem. The resource includes a list of research...

This booklet contains a range of suggested teaching activities and contexts for teaching about biodiversity at A level.  Topics covered include: sampling, species, Simpson's, diversity, conservation, population, and ecology.

Although produced to support the teaching of OCR AS and A Level Biology A...

From ARKive, this hands-on activity is designed to remind post-16 students about the concepts of biodiversity, evolution and Darwin’s theory of natural selection. By investigating biodiversity and the process of evolution students learn how traits beneficial for survival are selected for and genetically passed on...

This briefing discusses how bioethics issues affect us all and how we hear about issues which fall into this category on a daily basis. News items about...

This issue covers the background in selective plant breeding over the centuries and then describes the more recent advances and the introduction of...

This edition covers issues concerning assisted conception and "designer babies", which is a term which is often heard in the popular media. Today an ever-...

As human-to-human transplantation has become more and more successful, it has almost become a victim of its own success. There is a shortage of donor organs...

Stem cells have the potential to develop into different cell types in the human body and as such, can be used for tissue repair or, perhaps in the distant...

This unit looks at biofuels and how these relate to the climate crisis, fossil fuels and the food industry and whether they are the future of fuels.

In this unit students consider the relationship between the growing of crops for food or for fuel and conduct independent research to write a policy brief on...
