Performing Number Magic A9

In this resource from the DfE Standards Unit, students analyse simple number 'tricks', and explain how they work, using algebra. They then try to create their own variants of the trick, making it more impressive. Students will: develop an understanding of linear expressions and equations; make simple conjectures...

Loci in the Argand Diagram

This MEI resource for complex numbers demonstrates loci in the Argand diagram. In the complex plane the horizontal axis are real numbers and on the vertical axis are imaginary numbers.

The excel file uses sliders to alter the position of the point on the plane. The point can be picked up and moved into all...

Interpreting Distance-Time Graphs with a Computer A5

In this DfE Standards Unit resource, students interpret linear and non-linear distance-time graphs using the computer programme Traffic. This program provides a simple yet powerful way of helping learners to visualise distance–time graphs from first principles. The program generates situations involving...

Genes and Inheritance *suitable for home teaching*

In these resources from the ABPI students are introduced to genes and chromosomes, the role of genes in determining protein structure, mitosis, cloning technology, meiosis, inheritance, mutation, cystic fibrosis and possibilities for gene therapy.

Histograms

This is a series of interactive excel sheets that look at histograms.

The first sheet contains a histogram displaying a summary of time spent travelling to work. A new set of data can be generated at the click of a...

Vectors 2

The first two sheets use maps of New York to show how vectors can be used to specify journeys. Answers in terms of a and b can be revealed.

The third sheet shows that the vectors a and b used to describe relative...

Vectors

This interactive excel sheet deals with a variety of vector topics. It begins with sheets which require students to identify column vectors from line...

Nervous System: Synapses and Nervous Control of Muscle

From the National Learning Network Materials' Biology collection, this interactive resource looks at the nervous control of muscles. Animations look at neurotransmitters and the transmission of impulses at synapses and the neuromuscular junction. Muscle fibre motor units and the control of muscle contraction is...

Nervous System: Action Potentials

From the National Learning Network Materials' Biology collection. This interactive resource shows how nerve signals, or action potentials, are transmitted along a nerve cell. Students see the cell's resting potential and how an action potential is generated and propogated along a nerve cell. ...

Enzyme Action

This unit of learning material, from the National Learning Network Materials' Biology collection, explains enzymes and enzyme action. Animations illustrate the lock and key model of enzyme action. Students see how temperature and pH influence the enzyme's active site and therefore the rate of reaction.   The files...
