In this activity students are presented with a calculation of the standard deviation of seven athletes. Students are asked to comment upon the result. It is intended that students will spot that the standard deviation is too large given the data, but can students spot the error? This resource highlights the errors...

This activity highlights the difficulty finding quartiles for small samples sizes as there appears to be more than one method to be found dependent upon the book being used. In this activity a sample size of 11 is chosen as finding the quartiles for this sample size is straightforward. Students are told the number...

A Catalyst article looking at how to measure parts of carbon cycling as it happens in forests. Two of the processes used, flux towers and soil chambers, are described.

From the Integrating Mathematical Problem Solving project by Mathematics in Education and Industry (MEI), this activity shows that income is not equally distributed among all the inhabitants of a country. This can be shown visually using a graph and also measured. The mathematical ideas covered are:
•...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A reliable way to demonstrate photosynthesis in the classroom. When the pond-weed Cabomba is placed in a solution of sodium hydrogen carbonate in the presence of light of appropriate intensity, it...

A Catalyst article about experiments on surface tension based on a simple test that can be conducted at home or in a school classroom.

This resource is part of a collection of Nuffield Maths resources exploring Personal Finance. The demand is roughly equivalent to that in GCE A level.  The resources include slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant materials.

This explores how to...

This is a good introductory lesson to get students used to using a variety of measuring devices they might be unfamiliar with and which one you would select for a certain job.  The measuring devices are:

• vernier callipers
• micrometer screw gauge
• travelling microscope
• a metre...

Purpose: Finding the speed of an object is a fundamental step in understanding the relationships between forces, acceleration and motion. Practical measurement of speed in a classroom can be challenging as methods employed can be complex and time consuming. Using the camera function in a mobile computer (smart...

This action research report, published by LSIS, describes a project undertaken by Newcastle College. The study focussed on the impact of coaching or ‘active’ mentoring activity on the teaching practice of three additional diploma trainees.

The teaching unit ‘...
