Using ratio to represent relative distance
Team Hope, Team Curiosity and Team Perseverance used ratio to represent the relative distances of the planets from the Sun on the school playing field.
The challenge set was to use the best ratio tor representing relative distances of the planets from the Sun on the school field. The groups used different rations, until the most appropriate was found.
Using the ratio of 1,000,000,000,000: 1, the total distance from the Sun to Pluto is the length of the primary field. This means that every metre that we walked on the playing field is actually 1,000,000,000,00 metres in the solar system!
The photograph below shows the area of the ‘Goldilocks zone’ – the part of the Solar System that is just the right temperature to sustain life. It is neither too hot, nor too cold – itis just the right temperaure.
Scientists are currently investigating whether there was once life on Mars. We know that there was once water on Mars.
Yesterday (Tuesday) we used large paper to divide the distance of the planets from the Sun. We then used a trundle wheel to help us mark the relative distances on the field. On Monday we did the same thing, but we struggled because the paper wasn’t lined. We used lined paper yesterday and got a fun trip to the field. We showed the distance of Pluto from the Sun – the length of the whole field. I acted as the Sun and my friends acted as the planets. whole field. I was the ‘biggest star’ yesterday! Yesterday was fun.
