Activities should challenge, but not overly frustrate. If your child does not seem interested in doing a particular activity, suggest another one, or try it again at another time. Keep children's natural yearning for learning burning by not forcing them to do something they are not interested in doing, but by engaging them in motivating activities. Share your science interests. If you have a science-related job or hobby, such as keeping a fish tank, repairing cars, or feeding birds, share the excitement.
Nothing is as contagious as honest enthusiasm.
Do activities together. Bridge from the media. Older students may enjoy discussing whether the science presented in science fiction stories was real or fictional. In outer space there is a vacuum. Since sound waves cannot travel in a vacuum, space travelers would never hear the sound of a space craft as it passed by them.
