One of the problems with students who are on the ball is what do you do with them when you are letting the other kids catch up?
I have a slew of activities that I use for extra credit that I pull out when students get a day to get caught up. One of them is The Moon the size of a Pixel.
The site is pretty neat. It is a spacial map of the solar system putting the moon the size of one pixel and showing how much empty space is between the two. As you scroll, he will fill in some of the space with comments, usually about how much space there is.
Eventually you pass all the planets (there is a cheat scroll at the top to jump from planet to planet).
So, what does this have to do with English? Well, the assignment for those go getters is to scroll until they find the Shakespeare quote. Then they are to email me the quote and what Shakespeare play it comes from. I do not tell them where the quote is (that would take the fun away from it), but I will tell you. You'll find it between Saturn and Uranus (closer to Uranus). I had to fold the two screenshots up because the quote and explanation is longer than one screenful:
I love how this blends with his science lesson. The sayings that come beforehand talk about how it is impossible for us to comprehend some things such as the amount of space between objects in space.
I like this activity since it keeps students busy while others are working, it blends science and literature, and it practices research skills since the student will need to look up the quote to find which of Shakespeare's plays it comes from. This is even better if you choose to teach this play later on.
