Thanks everyone. Good information here.

This is a Grade 6 project and I was a little distressed to find that even
the basic concepts of electricity haven't been taught yet they are supposed
to build a basic circuit and working model.

For instance, my daughter assumed that to power two 6v lights, she needed a
12v power supply. Yikes.

So what's the problem? Connect them in series.

Or in parallel if the power supply is big enough. C cells may not be.

If you connect two 6V lamps in parallel to a 12V supply, you're quite likely
to see the two lamps doing an excellent imitation of fuses -- especially "if
the power supply is big enough".
