This is the last week of term 3 and in Year 7 Science we are doing another exciting science project with Mr Ardito’s class in New York. This project is to design and test the best paper aeroplane – but what defines ‘best’? We decided that, for this project, the best paper aeroplane is the one that travels the greatest distance in the air. Each group of three students tested one aspect of the plane – such as wing-shape, nose angle, length or style of plane. Then each plane was flown five times and the data was collected to obtain the average flight distance. You can view our videos here:

This week is Science Week around Australia, so we have planned some extra hands-on learning activities. This student is measuring the mass of her sports shoe, in grams and Newtons, for an experiment to test the co-efficients of friction of various surfaces. We use a spring balance to measure the static and sliding friction of the shoe on three different surfaces (carpet, vinyl and asphalt). Students compare their results of shoes with different tread patterns and discuss which sports require shoes with high and low coefficients of friction. Football boots and netball shoes require ‘grippy’ shoes, while ten-pin bowling and ice-skating require ‘slippy’ shoes.

The CSIRO have provided hundreds of do-it-yourself science activities you could try for Science Week – Here are some Physics activities, Chemistry activities and Technology projects. Also, the New Zealand government education department has some interactive science games to improve earth science and environmental education.
