SCIENCE WEEK

Our challenge is to build a moon buggy which is motorised and that will also use some kind of solar energy. Watch 'Liam' the avatar who helped set our challenge.

We investigated making axles and selecting the best axle for our purpose. We explored circuits with motors and batteries. We harnessed solar power with an LED light powered by a solar panel.

This project was dominated by problem solving, perseverance, helping others to understand and manipulate their materials.

We explored forces acting on the moon buggy as well as circuitry.

SPACE PROJECT - Does the height from which a meteorite falls affect the crater made?

Class 11 have investigated how craters are made on a planet. For this first experiment we changed only one variable - the height from which we dropped the meteorite. All the other variables such as the meteorite we kept the same for this investigation.

Our results were unusual! Most of us had predicted that the higher the fall would result in the largest craters. This did happen in the main, but the craters were not dramatically larger e.g. 20 cm compared to 100 cm fall was on average only affected the crater made by a couple of cms deeper or wider.

 

With unusual results, our scientists reacted like professional scientists and repeated the investigation.

 

Superb teamwork was shown and many children were able to record and analyse their results and form their own conclusions.

TOILET PAPER SOLAR SYSTEM!!

 

Class 11 used toilet paper and fruit to represent the solar system to understand the enormous distances between the sun and the planets. The fruit helped us to understand how the size of the planets also varies so much. For example, Jupiter was represented by a watermelon compared to Pluto which was a tiny blueberry. Earth and Venus are similar in size so we used an apple.

 

The scale used for the toilet paper was; 1 sheet of toilet paper represented 25 million km in space. We used in total 236 pieces and Leah worked out the total distance!

 

We were amazed at the size of our universe!
