Biscuit experiment - ingredient functions

Experiement looking at the ingredient functions in biscuits spread over two lessons.  Powerpoint and differentiated worksheets to complete based on the experiment. 

Magic Melting Ice Cubes

Simon Quinnell, from the National STEM Learning Centre and Network, shows how to carry out some ‘magic’ at the Christmas dinner table using ice cubes, a plastic chopping board and a frying pan.

When asked to feel the plastic and the metal, people usually describe the plastic as warmer to the touch. They are...

Jelly Liquidiser

In this Christmas table experiment, Simon Quinnell, from the National STEM Learning Centre and Network, demonstrates why pineapple should not be added to jelly. When he adds pineapple to a bowl of jelly, the jelly liquefies due to the action of an enzyme in the fruit which breaks down the gelatin.

This is...

Jumping Candle Flame

Simon Quinnell, from the National STEM Learning Centre and Network, shows how to carry out some ‘magic’ at the Christmas dinner table using a candle and a match.

After letting the candle burn for a minute, Simon blows the flame out so that the smoke continues to rise above it. Then when a match is placed...

Magic Gas

Simon Quinnell, from the National STEM Learning Centre and Network, demonstrates the properties of gases in this surprising Christmas table experiment. He drops an effervescent digestion tablet into a wine glass containing some water to generate carbon dioxide.

The carbon dioxide is heavier than air, and...

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...

Flying Tinsel

Simon Quinnell, from the National STEM Learning Centre and Network, demonstrates static electricity and charge using a balloon and a piece of plastic tinsel. Rubbing the balloon on a jumper builds up a negative charge on its surface.

When the positively charged tinsel is dropped onto the surface of the...

Go with the Flow: Investigating Bouncy Fluids and Other Strange Materials

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). There are a wide variety of materials that have unusual and interesting flow properties, and which find applications in industry and consumer goods. The booklet introduces a selection of...

Extraction of DNA

In this experiment, students can extract DNA from a variety of animal and plant materials that can be found in a household kitchen. The video shows how DNA can be extracted from an onion, and can be performed as an individual or group...

Cutting Edge Materials: Practicals

Six groups of practicals produced by the Institute of Physics (IOP) that help students to find out more about how science is applied to using and testing new materials.

In addition to the guidance included for specific activities, please refer to the generic health and safety information before commencing...
