### Fractions: Mixed Numbers

Converting between mixed numbers and improper fractions – The explanation begins by showing the difference between a proper fraction, an improper fraction and a mixed number. Pictorial representations of the fractions are used to aid understanding of how a mixed number and an improper fraction represent the...

### Electrical Installation *suitable for home teaching*

Produced for Future Morph, these resources contain a video in which a student talks about her apprenticeship course in electrical installation at Exeter college. She describes the entry qualifications needed for her course, contrasts her experiences at college compared to school and briefly...

### Electric Sausage

In this video, produced by the National STEM Learning Centre and Network and the Institute of Physics, Michael de Podesta has a unique twist to demonstrate static electricity and charge. Small pieces of paper are attracted to a statically-charged balloon. Amazingly, so is a sausage. This short video illustrates...

### Itching for more

Designed for students who have advanced through Scratch and are ready for additional challenge, this resource explores Build Your Own Blocks (BYOB) as a tool for learning modular programming using procedures.

After examining, briefly, the history of the computer and the Turing Test as a measure of their...

### Starting from Scratch

Scratch is widely used in primary schools to teach children basic programming. This resource goes deeper, making use of the familiar Scratch environment to take students deeper into programming concepts such as:

• Algorithm design
• Parallel and sequential instructions
• Event-driven...

### I love my smartphone

Mobile app development is an engaging way for students to learn programming and interface design as many do, indeed, "love their smartphone".

This complete learning package teachers the origins and development of the smartphone, helping them to appreciate the amount of technology packed into their pocket. It...

### Demonstrations for the Christmas Dinner Table

In this National STEM Learning Centre and Network video, Simon Quinnell demonstrates four experiments, with the theme of Christmas, that teachers can do in the school laboratory.

These are:* Tea bag convection - see how a burning teabag mysteriously rises on convection currents in the air around it.* The...

### Dry Ice Demonstration

In this National STEM Learning Centre and Network video, Simon Quinnell demonstrates an experiment using solid carbon dioxide (dry ice) and sodium hydroxide which is likely to impress students. The experiment can be used to talk about the properties of solids, liquids and gases, acids and alkalis or used as an...

### Ice Melting Blocks Demonstration

In this National STEM Learning Centre and Network video, Simon Quinnell investigates the way different materials conduct heat using conductivity blocks and ice cubes. The video shows how the ice cubes melt at different rates depending on the thermal conductivity of the materials they are sitting on. Simon...

### Cannon Fire Demonstration

In this National STEM Learning Centre and Network video, Simon Quinnell demonstrates a spectacular and noisy experiment showing the oxidisation of hydrogen peroxide using ethanol and potassium permanganate. An exciting illustration of energy changes, the...
