In this cluster of articles, students investigate aspects of plant biology and behaviour including chloroplast genes and how they have helped biologists understand plant evolution; how plants monitor the intensity, direction, colour and duration of the light they receive and if attacked by herbivores or pathogens...

This task assesses understanding of scatter diagrams. A scatter diagram is presented that shows the lengths and widths of the eggs of some American birds.

The task involves plotting additional points on the diagram, describing correlation, interpreting a point on the diagram, and estimating the width of an...

This task assesses scatter diagrams and lines of best fit.

A scatter diagram is shown of the length and width of birds eggs. There follows a series of five short tasks on:

• Plotting an additional data point
• Making a statement about correlation
• Making an estimate of width from a...

In this resource from CensusAtSchool. students compare data on month of birth from 45,000 South African students given in a table to the same data represented in a bar chart. Students are asked to consider reasons for month of birth and why it is appropriate to use percentages for large data sets.Students are then...

In this activity the goal is for students to understand how the regression line is chosen. Autograph has a built-in facility for showing the squares of the residuals and is required to make this task work. Students are asked to explore what the lines that give the sum of the y-on-x residuals equal to zero have in...

In this activity, students are challenged to produce a scatter diagram consisting of ten points that give a product moment correlation coefficient of exactly 0.99. Students are expected to appreciate that the points will lie almost exactly on a straight line with at least one point being slightly out. The answer...

This Core Maths resource includes data from which students can calculate correlation coefficients. The resources includes a card sort that matches up scatter-graphs, data tables and product moment correlation coefficients. 

The teachers' notes give detailed teaching suggestions on how to introduce and...

This series of activities from NASA take a mathematical approach to looking at black holes. They are intended as supplementary problems for students looking for additional challenges in the maths and physical science post-16 curriculum. Problems consist of a student page and an answer sheet. Students need to be...

This resource includes data on blackbirds caught and ringed in a single garden in the UK across a period of several years. It includes interesting background information on the migratory habits of these birds, and the characteristics of European and ‘British’ resident birds.

The data, which is a rich source...

In this activity learners will to countdown backwards using different steps i.e. 1s, 2s, 3s, 5s and 10s. This will prepare learners to count to and across 100, forwards and backwards, beginning with zero, or from any given number. To enhance engagement, learners will release balloon ‘rockets’ when each countdown...

This STEM activity supports pupils to follow a set of verbal instructions to successfully navigate a maze made from tables whilst blindfolded. Pupils will understand the importance of clear instructions when instructing others and to be able to use mathematical vocabulary such as whole, half, quarter and three...

This excel file has four interactive sheets dealing with the order of operations. The first shows groups of calculations involving addition, subtraction and multiplication where the answers can be revealed. The second interactive sheet is similar, but it deals with...

In this activity, from the Institution of Engineering and technology (IET), students investigate a use of electronic systems to improve health care.

They study a case where a Body Centric Antenna (BCA) increases the...

Body centric communications is any communication on, within or around the body using wireless technology. In this film, engineers give examples of the applications of this technology, including wireless devices which monitor blood glucose and communicate directly with a device which can administer insulin. This...
