In this activity students use chromatography to separate the dyes in sweets. The resource looks at the information on food labels and provides some questions for students to answer about fat, sugar and salt content.

Students then place sweets on filter paper, adding water to dissolve the food colourings....

From The Centre for Industry Education Collaboration (CIEC), these activities investigate the crystallisation of sugar in the fondant of creme eggs.

Complaints of 'glass' in creme eggs, and other sugar confectionery products, are sometimes the result of the growth of very large crystals of sugar. In these...

Produced by Science & Plants for Schools (SAPS), this investigation looks at the taste of different fruits and vegetables. Domesticated fruits and vegetables have all been selectively bred so that they contain a particularly attractive taste for humans.

In this activity students carry out an activity to see if they can tell the difference between drinks that contain sugar and those that contain sweeteners.

Students learn about chiral molecules and how sweeteners can...

In this activity, aimed at primary level children learn about micro-organisms and hygiene by looking at swine flu and its symptoms. Using data on the number of cases of spine flu in the UK children discuss how viruses are spread, consider how they can be contained and learn how scientists use current data to revise...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Understand that a chemical formula provides information on the composition of a substance.

• Select an appropriate chemical formula for a given, simple, molecule.
