Visit science centers in your area, watch science shows and documentaries, watch rocket launches together. We have science nights where kids can ask how something works and then we white board explaining how it works. Or we just pick a topic and white board it. Lego mindstorms, check out Lego First Robotics League, if you can't find a team to join you can create your own team. They have a few options for different age groups. Do science kits, chemistry and electricity. Do your own experiments like rubbing a balloon then holding it by a stream of water in the sink. There are thousands of cool experiments and projects out there. Kids are naturally interested in this stuff. When they are a little older arduino projects are good fun for the kids and adults.
