The amazing concertina cactus
Resource
Do you have a dried up cactus lurking in your classroom? Treasure it – it is a valuable educational resource.
In this investigation involving a commonly found plant (a cactus), pupils will have the opportunity to:
- measure accurately using appropriate scientific and mathematic equipment
- understand how important it is to take repeat measurements
- work in a team
- observe what changes over time
The class is encouraged to explore the changes that can occur when a dried cactus is watered over a period of time. Included in the Teaching Notes is a case study detailing how the investigation came about and providing example results. Cross-curricular links can be made with Maths, Art & Design and Literacy.
