Going deeper ... students build 3D water molecule structures to understand the cohesive properties of water and how each molecule (H20: 2 hydrogen + charge and 1 oxygen - charge) bonds together.
Hydrogen bonds and surface tension give water some amazing properties. Here students see how many drops of water fit on 5, 10 and 25 cent coins. How many drops of water do you think you could fit? There was only one way to find out… by adding one drop at a time!

In this simple memory game, students were encourage to work together, exploring mathematical patterns.
Students from each group have four 15-second opportunities to look at and 'memorize' a printed sheet of related mathematical patterns. The groups then have to reproduce the information they've seen on the sheet for themselves.
The principle behind the activity is that the sheet is easier to reproduce by using mathematical insight than by trying to remember the whole thing 'cold'.
Students learnt about the tallest structures in the world and the structural engineering that goes behind building these amazing towers. Click here to see what students learnt.
Later students were given a challenge: Build the tallest structure! However, each group only had 3 pieces of paper and 70 cm of masking tape. In addition, each structure had to withstand a gust of wind for a minimum of 15 seconds (we used a hairdryer). Before they began building, they needed to brainstorm, draw out drafts and answer questions that would help them with their design.
