The Science Castle offers a wide selection of science projects. From kindergarten science experiments to investigatory science projects. And our selection is growing.

If you have a science project idea yourself please click here to submit it.

In order to do or submit a science project you need to be a registered student at the Science Castle. But no worries the membership is completely free of charge. After completion of each project you will earn knowledge points and you will be served with an official Science Castle certificate that you can send to us in order to obtain the original signature of Professor Dr. Franciscan, Headmaster at the Science Castle.
