Astronomy has always been a favorite topic of mine. From the time I was a child, I have loved learning about the planets, stars, other galaxies, black holes, supernovas, and more.
One thing that I have always struggled with though is grasping the actual scale of space. This is a common problem for most of us, and something that can really help our students better understand scientific concepts they are learning in school.
So how can we get a better understanding of the massive scale of the universe and the objects contained within it? One option is to use simulations that can help model space. Thankfully there are several excellent online, interactive simulations that can do just that.
See below for four of my favorite space simulation sites. Each approaches the concept of scale a little differently, so check each out to see which ones will work best with your students. And be sure to let me know of other scale simulations you have found that I can add to this list.
