Last term a lot of students asked Mrs Baldwin if our next Science topic could be about Space. Their wish was granted because this term we will be learning about the Solar System. We will be looking at the relationship between the Sun, Earth and Moon, we will also look closely at the moon and its phases along with the 8 main planets.
Today we began by discussing the size of the Sun, Earth and Moon. We compared the Sun as a size of a basketball, Earth as a marble and the Moon as a single peppercorn. We asked the question that if the Moon is so small compared to the Sun, then why is it that when we see the Moon in the Sky it is a similar size than the Sun? We talked about that the Moon is very close to Earth compared to the Sun which is why it looks quite large at night time.
Next we then investigated how far away each planet is from the Sun. To do this we used something you would not use very often in a science lesson – toilet paper. We were given the distances of each planet from the Sun and these distances were then scaled down by using toilet paper pieces.
Firstly we counted out how many pieces we needed for each planet.
Then in small groups we went outside and laid out each length of the toilet paper so we could see the different distances each planet has from the Sun. Unfortunately the weather was against us and the strong wind and then rain made it hard to complete. However Room 9 are persistent workers and next week we will complete the measurement activity with the entire class.
We also recorded the distances of each planet from the Sun by drawing a graph.
Mrs Baldwin gave us a moon diary to complete over the next month. Each night we will be recording what the moon looks like and record this in our journal. It will be interesting to see how the moon changes each night. Our results and discussions about the moon phases will be posted on our blog later this term!
