Now, you’ve made a solar system – let’s get some idea of how vast that solar system is… for this you will need a wide-open space and some skewers. Initially we printed little planets for colouring. (Alternatively you could bring the solar system that you just made, but with a little wind in the air we thought it safer to opt for the smaller representation of each planet!) Attach each planet to a skewer with tape and head to a wide open space (we went to the local sports field). Place your sun in the centre of the field and begin to measure your planets. For accurate measurements of the distances between planets you can look here. We chose to be more approximate in our own measurements, with ‘kids steps’ as our form of measurement, and the furthest being 30 steps from our sun (to allow for shorter counting attention span of the 3yo!) Each time you pace out your planets, place your skewer as a marker. You should end up with a little gathering of planets near your sun, then some so far away that you can barely see them! (Well, 30 large steps away at least!) Before you head out you may like to watch this demonstration that I was delighted to find (after doing ours, but still great to watch!) – he did it on a slightly larger scale but has some great facts about the planets that you might like to include when you are doing it with your young ones. Once all in place have a look at how long it takes to walk around the sun if you were Venus, or perhaps Mars… now how long does it take to you to move around the sun if you were Neptune! (See Neptune (3yo Elka) taking a bit of a shortcut as she orbits the sun (5yo Anica) below) Depending on your young ones you may like to talk about how our Earth year is determined by a rotation around the sun. (We will be looking at weather a little shortly, so we’ll answer some of those seasons questions in the coming week!) – and make sure you bring your planets home again, they will be useful for our upcoming galaxy play-dough!
