Inside STEM careers: investigating antimicrobial properties

Produced by Science & Plants for Schools (SAPS), these materials look at the work of the plant biologist, Julian Ma. Through seeing how natural and genetically-modified plants can produce medicines, students gain a greater understanding of the career opportunities available in plant biology.

Julian is...

Gum Fun: Investigating Plant Gums

Plant gums are often used in the food industry as thickening and stabilising agents. Gums are water soluble polysaccharides, such as starch and cellulose. In this activity, students investigate what happens to the texture when different polysaccharides are mixed.

When solutions of some polysaccharides are...

What Is Wood?

This student sheet invites students to consider lignification in detail. Students take thin sections from successive internodes of the shoot and calculate the lignification index of each section. These can then be compared with sections from other parts of the plants to consider where lignin is deposited in other...
