Activity 1

In your pairs you have been given a set of different weights (with no labels) and a set of scales.

Use the scales to sort the weights into order from heaviest to lightest.

Use the scales to sort the weights into order from heaviest to lightest.

Activity 2

Write down a list of steps that tells someone else how to sort the weights into the correct order.

This list of steps is your**sorting algorithm**.

Activity 3

Use the lego and flip cams you have been given to create your own example of a bubble sort.
