We developed a number of questions and put them on clip boards.
In our research we discovered that there are a number of types of bridges including arch bridges and beam bridges.
We observed that Harold’s Cross Bridge is an arch shaped bridge
while Portobello Bridge is beam shaped.
Portobello Bridge has a lock. The ropes can be released to open
the lock gates and increase the water levels and allow boats through.

Eco Friendly Newspaper Bags

Take a look at our Eco friendly bags. We researched gift bags and discovered that the majority of them are made in China. We wanted to reduce the air/land and sea miles used and thereby reduce our carbon footprint by making bags of our own using old newspapers.

Design a Bridge Challenge

Task: Design a bridge


Using blocks, paper, books and crayons to test we designed bridges to see which ones were stronger and could hold the most amount of crayons. We manipulated our structures to increase their strength by folding the paper used, using double layers of paper, creating arches and structures for extra support.


The material from which a structure is made is important but you can strengthen a material by changing is shape. Bridge designers often use different shapes for example: arches and triangles. The curve of the arch spreads the load on the bridge and makes it stronger.

STEM Activities in Room 10!

We completed two light experiments last week to show the splitting and mixing of light/colour.

Experiment 1: We made rainbow spinners to show that when the rainbow colours are spun quickly, your eyes can’t keep up and the spinner appears white.

Experiment 2: We explored white light and colour by placing skittles and the outer circle of a plate. We added water and observed what happened. The colours moved towards the middle and created a whirl of colour.
