Class finished 5 minutes early…. now what?

As much as we would love to have our lessons end 30 seconds before the bell rings, it rarely happens. Even if it does work out perfectly in 1st hour, 2nd hour is a completely different group of students and the lesson might require more or less time. It sometimes happens that the lesson is over and I still have 5 minutes left of class. It drives me crazy when students try and wait by the door! If you are a science teacher, here is a great idea to fill those last 5 minutes.

There is a show on science channel called Outrageous Acts of Science. During the show they show video clips and have scientists explain the science behind the video. The videos are all about 2 minutes long and fun for students to watch. Go to and type in “Outrageous Acts of Science” in the search bar. You will get a ton of results. Pick out a few that are interesting. Then, head over to and copy the youtube URL into the keepvid site. I like this website because it allows you to download youtube videos and save them to your computer. That way you don’t have to worry about commercials or streaming/buffering issues.

Another fun youtube channel is from Steve Spangler and is called “Sick Science.” Click here to view the youtube channel. It shows simple science experiments and allows the students to brainstorm why they happened. It is great to have students discuss why they think something is happening and not just have it explained to them.

You are probably aware of Ted Talks on YouTube, but did you know they have Ted riddles? You can find a playlist of them here!

If you have some of these videos already picked out and ready to go, it will save you time later. I think you will find these clips are way more valuable than the students trying to sit on their phones or wait by the door. Any other ideas you use for those last 5 minutes? Drop them in the comments!
