In this activity, students collect and record data1 and use it to create 2D and 3D images of an unseen surface. They will then understand some of the processes involved in mapping the unknown.
By the end of this activity, students should be able to:
- use a probe to scan data points of a hidden surface
- create a data sheet for the hidden surface
- use the data to create 2D and 3D images of the hidden surface
- briefly explain how nanotechnologists use tools to create images of things at the nanoscale2.

Probing fridge magnets – in this activity, students investigate the pattern of magnetic fields on a fridge magnet3. This will give them an idea of the principle behind scanning probe and magnetic force4 microscopes.
In the Multibeam seafloor survey activity, students create a model seafloor and create a map of it through taking depth readings.
Modelling animal cells in 3D imitates what can be seen under high-resolution microscopes. Using lolly slices to build 3D images and Using shadows to build 3D images model how scientists interpret microscopic data.
- data: The unprocessed information we analyse to gain knowledge.
- nanoscale: Refers to dimensions below 100 nm. Also refers to the small size, often only a few nm, at which the properties of a substance are different to properties of bulk material.
- magnet: An object that generates a magnetic field that can influence magnetic objects such as iron and other metals.
- force: A push or a pull that causes an object to change its shape, direction and/or motion.
