Some excellent watery demonstrations this week!

Cleo resource

A resource I use regularly to demonstrate ‘real life graphs’ comes from the excellent **CLEO Resources** (Cumbria and Lancashire Education Online).

**Fill the various flasks with water and investigate how the height of the water varies with time.**

Archimedes from Colmanweb

Or you might like Archimedes in his bath!

From the **Connected Maths Project** (Michigan State University) comes this very clear demonstration for exploring the relationships between the **volume of various geometric shapes. **

Connected Mathematics Project

Fill a shape with water then drag it to another shape to empty the water into that shape!

(Other activities I particularly like on this site include tessellations and the isometric drawing tool from the **6th grade resources, **Virtual Box from the **7th Grade resources **and the Painted Cubes investigation from the **8th Grade resources**.)
