Year 7’s Space Out!
By Tom S. (7K)
This Term in Science, we have been studying Astronomy. As a Key Assessment Task (KAT), we created a presentation explaining natural phenomena such as the seasons, tides and eclipses. We also did an experiment testing how high we could jump on each celestial body in our Solar System. I jumped 0.75m on Earth but on the sun, I only jumped 0.03m – I barely got off the surface! On Pluto, (which technically is not a planet) I jumped a whopping 12.5m! We found out that we could jump higher on Pluto than the sun because of the gravitational pull. The amount of gravity a planet has relies purely on how much mass it has. Jupiter is a huge planet, so it has a huge mass, therefore a huge gravitational pull. Another thing we learnt about gravity was that weight changes depending on which planet you are standing on (but your mass stays the same). Let’s say I weighed one kilo on Earth, on the Sun I would weigh as much as a black rhino!
