Within this one hour resource, students play the role of fire safety employees whose task is to find the most efficient placement for detectors. Students are given constraints within which they should work and a series of problems to solve leading to an algebraic solution to the problem.

The activity is...

This one hour activity demonstrates how bimetallic strips work in smoke alarms.   Using the context of the Internet of Things and fire safety, students design, make, test and refine a sensor to detect heat and produce an electrical output that could be used to switch on a fire alarm.  This resource provides a...

A highly technical overview of how sound is represented in a computer, how digitising sound changes the quality of it and how reducing the sample rates can effect the resulting audio. The resource also comes with a number of sound samples to illustrate these concepts, along with both Python and Scratch programs to...

Students arriving in Year Seven may bring with them very different experiences of science. This unit from Salters' Science Focus is composed of over 50 short activities, divided into nine sections, which can be used as a ‘pick-and-mix’ resource to introduce students to the procedures and equipment in a secondary...

This resource contains a shorter and longer version of an assembly which can be used to introduce schools to SAMHE. If your school does not have a monitor, you can use the downloadable presentation below entitled 'Introduction to SAMHE: presentation NO MONITOR'.

SAMHE introductory...

In this activity students evaluate the advantages and disadvantages of using biological control to halt the invasion of common ragweed, Ambrosia artemisiifolia. This is an invasive plant which is spreading across Europe. Because of illness caused by its allergenic pollen and competition with crops, it costs...

This resource from Arkive allows students to investigate the impacts that invasive species have on the environment, the effects that they have on native species and habitats, and the characteristics that make certain species good invaders. The activity looks at the different ways in which invasive species can...

A quick audit for teachers to use to consider their own social and emotional skills.

Inverse Functions. Linear
This file starts with an example of how to find the inverse of a linear function. New examples can be generated and the graphs of both functions...

This interactive excel file has separate sheets which deal with inverse proportion where the functions are linear, quadratic and square root. Each sheet begins with a statement of the proportional relationship and values so that the constant can be calculated and the...

Carom Maths provides this resource for teachers and students of A Level mathematics.

This presentation begins with a reminder of some transformations of the plane before introducing the less well known transformation of Inversion. Students are able to experiment with an Autograph file to explore this concept...
