How can I form the title for my science fair project to glue onto a backboard?
Acrylic paint and a stencil works quite well.Get an art stencil with big letters, rule some long straight lines (to align the letters), then carefully paint the letters onto the board with a small paint roller. Be careful to let each letter dry before painting the next letter - but Acrylic paint dries quite quickly, so this shouldnu2019t be a problem.If you canu2019t get an art stencil, you could making your own stencil by printing big letters on printer paper, then cut the letters out of printer paper using a craft knife.
I would like to do a science fair project comparing Windows to Linux. I need to come up with a question that can lead to a hypothesis, then apply the scientific method to test this hypothesis. Could someone help me to come up with the question?
Why do you want to compare them? That's a good starting point for coming up with a project.For example, maybe one's faster than the other, in general. You could measure the actual performance difference -- get two identical computing platforms (PC's, tablets, smartphones), and measure how much overhead each is imposing on the hardware.Maybe you think one is more usable than the other. You'd have to find a way to measure user efficiency -- number of compatible device drivers, number of library entries, human efficiency when using the OS...Maybe you think users like using one more than the other. Do surveys, literature searches...Perhaps you believe one is more reliable than the other. You could try to find crash statistics for each. You might be able to find this data for Linux, but I'm skeptical that Microsoft would share theirs. Still, you could try.These two operating systems are products of very different development methods. You could consider trying to elucidate how these methods result in different products and organizations.Or you could do a point-by-point, side-by-side comparison of, say, the new Windows 10 to the latest and greatest Linux distribution. That would actually be of some considerable interest and value to many folks.
