In this resource from the DfE Standards Unit, students create and solve their own equations where the unknown appears more than once and learn that there may be more than one way of solving such equations. Before doing this activity students should be able to solve equations where the unknown appears only once....

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop the idea that substances in the solid state usually consist of crystals, even though...

This interactive excel program enables students to investigate cubic functions and the relationship between the factorised form and the graph.

The first activities require the student to use the factor theorem to...

This interactive excel file begins with a sheet showing the dimensions of a cuboid beside an oblique drawing of the cuboid. The student needs to calculate the area of the three different faces, the total surface area and the volume of the cuboid. The dimensions can be...

The first two sheets of this excel file shows sets of data about the weight of cows in two herds. The cumulative frequencies can be revealed and the quartiles and median are shown derived from the cumulative frequency graph. The next sheet shows the comparison of the two herds as shown by the box and whisker...

Produced by the Wellcome Trust Sanger Institute, this resource contains an overview of the techniques involved in making a BAC (Bacterial Artificial Chromosome) library. It consists of an animation that covers the key stages in the process:

From the Wellcome Trust Sanger Institute, this animation shows a detailed overview of the processes involved in the dideoxy or Sanger method for sequencing DNA. This is the method used to sequence the human genome. The animation demonstrates the principles and techniques involved in the Sanger sequencing method,...

This animation, from the Wellcome Trust, illustrates how the DNA code is used to build protein molecules inside our cells.

It shows how, during the process of transcription, polymerase unzips the DNA and uses it as a...

In this activity students consider the questions: How does heat energy move around? How can we model the flow of energy and changes in temperature? What can be done to prevent hypothermia? Why do we need to try so hard to stay at the right temperature? In order to survive and be comfortable in hot or cold...

In this activity students consider the questions: Where does rain water go? How can we model the flow of rainwater in real life? What can be done to prevent flooding? When is rain dangerous? Where do floods come from? How can we reduce the damage that flooding causes? Over the last decade some parts of Europe have...

The first sheet of this excel file shows the number of passengers per flight from London to Paris. The raw data is shown in a grouped frequency table and the midpoint of each group can be revealed as well as each stage in the calculation of the estimate of the mean. The next two sheets each show two sets of data...

This series of interactive excel sheets aimed at Year Two students explores data tables and graphs. New questions and data sets can be generated each time by the click of a button.

The first five sheets generates a...

This series of interactive excel sheets aimed at Year Three students explores collecting data, entering data into tables and drawing graphs. New data sets can be generated each time by the click of a button.

The first...

This resource is based on the Inventive podcast. The podcast mixes engineering fact with fiction. Each podcast features interviews with engineers. In this activity, CEO and chemical Engineer Enass Abo-Hamed, and integration engineer Majot Chana are the inspiration for George Sandifer-Smith to write 'Data is Truth...

This selection of spreadsheets, designed by the Primary National Strategies to aid teaching and learning, tackles data, graphs, charts, measures and money, in a variety of ways.

Carroll diagram allows either shapes or numbers to be dragged into an either one or two criteria table. The...
