Stresses and Strains in Plants
From Science & Plants for Schools (SAPS), these practical activities allow students to investigate how woody and herbaceous plants support their shoots, branches, flowers and fruits and shed them at the appropriate time.
A number of investigations are suggested that can be adapted for students over a range of age groups. In measuring the biomechanical properties of plant structures and tissues, students can generate, analyse and interpret data to gain a better understanding of plant biology.
The investigations include:
* testing twigs for stiffness
* measuring the force needed to pull off a leaf
* investigating the forces needed to bend or compress plant tissues
* measuring the forces needed to peel fruits
