WB+6Sept10

Week Beginning 6th Sept 2010

__**To use properties of 3D solids**__

Useful resources for the start of the week; [|Volume of Solids] [|Useful volume and S/A formulae]

What do you already KNOW or WANT TO KNOW about surface area and volume? __Challenge #1;__ Create a square based pyramid of base (w x w) and height of W/2. Create a cube of dimensions (w x w x w). Consider how their volumes are related- use sellotape and sand/ sugar to test your ideas.
 * Monday**

__Challenge #2;__ Create a cone with a base with a radius of r and height of h. Create a cylinder with a base with a radius of r and height of h. Consider how their volumes are related- use sellotape and sand/ sugar to test your ideas.

What do you STILL want to KNOW about surface area and volume? Download the Excel calculator of Volume and Surface Area
 * Tuesday**

Gutter Problem- Back slightly to 2D, but with elements of 3D properties involved in this tricky problem. Extending your understanding of cross sections, areas and volumes of solids.
 * Wednesday**
 * Thursday**
