Why should teachers care about what happens in the brain?

 How can a scientific understanding of how the brain works inform the way you teach?On our free Science of Learning online course, teachers from all over the world have come together to work out their meaning to the big question ‘what is learning?’ Throughout the course, participants are exploring the science behind how students engage...

What are antibubbles and how are they changing the world?

Add a twist to your lessons on states of matter by investigating antibubbles.What are antibubbles?Most students will be familiar with bubbles that can be created by blowing air into a film of soapy water. These bubbles consist of a volume of air enclosed by a membrane of liquid. The bubble is held as a sphere by forces between the liquid molecules...


Teaching secondary science outside the classroom

Going outside can add a sense of occasion to learning and make a lesson memorable. With better weather on the way, we asked around the office for some favourite ways to take the lesson outside. Here’s our top six physics activities and top four chemistry activities: Top six outdoor physics activities:Model the...

Top five resources from Scientix

It is always exciting when you come across new resources to use in the classroom, especially when you know they will motivate and engage your students. I recently decided to take a look through some of the many resources that Scientix have to offer. Scientix promote and support a Europe-wide collaboration among STEM teachers,...


Ideas for enrichment and enhancement from the Triple Science Support Programme

All teachers recognise that some parts of science can be difficult or less exciting to teach and this can be even more problematic if it is outside your area of expertise. Similarly some areas lend themselves to extension through links with external agencies or by direct contact with ‘real world scientists’.The Triple Science Support Programme has...


Teaching A level chemistry: modern analytical techniques

Modern techniques of analysis have revolutionised the determination of the structures of organic molecules. Until relatively recently, the history of the Nobel Prize for chemistry is littered with prizes won for determining the structure of natural products (natural product synthesis). The only way to identify the structure of a molecule was to...


Teaching A level biology: human impact on ecosystems

Humans are part of the ecological balance and their activities can affect ecosystems, both directly and indirectly.In this topic at A level, students are required to consider the effective management of the conflict between human needs and conservation to maintain sustainability of resources and promote biodiversity for the good of the local,...


The Amazing D30

A material with a split personality, combining Textile, Product Design and Engineering!D30 is runny, like orange slime, when it’s moving slowly. But if you hit it with a hammer it’s as hard as metal. Wow!Helmets, motorcycle jackets, footwear, phone cases, clothing for stunt actors, and even boxing gloves can all be made using D30. You can see some...

Tales of parasites

We have just been given permission to host a series of TED Talks in the eLibrary, which meant that I had to spend a few days searching through the 1700 videos to find talks which were suitable for the classroom - in other words, those with age appropriate language and good links to the curriculum. It wasn’t a chore! The talks are strangely...


How bacteria talk

Part of my job recently has been to create resource packages linked to each statement in the 2014 KS3 Science National Curriculum to support teachers in their planning and preparation. Of course, while I was looking for resources for one topic I was distracted by resources for other topics which looked too interesting to pass by...One such...
