Here is an introduction worksheet to The Nucleus video from Teacher's Pet (video link is embedded at the top of the worksheet). There are twelve questions that go along with the video. There is one HOT question short answer response that students can use their just learned material about the topic to design an experiment to test the nuclear force of an element/atom.
This worksheet can be used in class, at home, or for review. Great for middle schools students who are being introduced to this topic. Good review for high school students who need to have a quick review.
