We began our new Science topic by working together in groups to discuss what we already knew about 'Earth and Space'. We placed the statements in different places depending on whether we thought they were definitely true, we weren't sure or whether they were definitely false. We then created our own solar systems in our pockets. This activity helped us to consider the order of the planets as well as their distance in relation to the sun.
The Big Question
‘Is there a pattern between the size of a planet and the time it takes to travel around the Sun?’
We explored the planet fact cards to look for patterns and relationships.
We worked with a group to investigate and explore the different phases of the moon. We used our ping pong balls on sticks to model how the moon moves round the Earth and to help us understand why the moon appears to change shape throughout the month. We then worked in small groups to use Oreo biscuits to represent the different phases of the moon.
We have been working on carrying out a fair test to investigate orbit times. We used a ping pong ball tied to a string to model a planet and its orbit. We changed the size of the string so it was a smaller or larger orbit and then timed how long the orbit would take. We will now look closely at our results to determine if we can prove that the further the planet from the Sun, the longer the orbit time.
We used our results from the Orbits investigation and displayed them in a line graph. This helped us to interpret our results more easily. Some of our graphs looked completely different to each others, which led us into a discussion on how difficult it was to keep the test fair.
