Rock-it Science Experiments: Free Videos

“Science, which is basically just knowledge, is growing so fast, there’s no way the schools or the books or videos or anything else can keep up with it. It’s up to the child to want to do this on their own. So we create it. We present it in a way so that they’re hungry to learn more and they’ll always be hungry to learn more.”

-- John McChesney, Founder & Director, Rock-it Science

Boy lighting match

“How to Light a Match”
In Rock-it Science lessons, we do dangerous things. We use hot glue guns, sharp knives, matches, high voltage, and dangerous chemicals. In the process, the students learn how to deal with dangerous situations in a manner that will enable them to keep themselves and others from harm. In this short video, Rock-it Science students learn the correct way to light and handle a match, then get some practice using flames in their experiments.
