Bivariate Data, Regression and Correlation: Residuals

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...

Bivariate Data, Regression and Correlation: Ten-Point PMCC

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...

In 'Black flag: a coding club mission', problem solving skills are tested as the reader joins Cal on a dangerous adventure into the underground world of the anarchists who are fighting to restore freedom to the...

Black hole in the Milky Way

In this video from the European Southern Observatory, we go to the centre of the Milky Way to investigate a supermassive black hole. Two scientists describe a 16-year long study, which used several of ESO’s flagship telescopes, to produce the most detailed view ever of the surroundings of the monster lurking at...

Black Hole Mathematics

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...

Black Holes

This animated clip explains in 1931, Subrahmanyan Chandrasekhar, calculated that if a star is big enough, that at the end of its life it can collapse to create a black hole from which nothing can escape. In fact, we are told, you can make a black hole out of anything as long as it is big enough.

Black Holes

This film, from Twig World, looks at how dying stars transform into black holes and are areas of mass so great that even light can't escape.

The key points made in the film are:

•When a star dies, it collapses and condenses into a single point, known as a singularity.

•The gravitational pull...

Black holes

This article explores the relationship between black holes and gravitational waves.
