I could only think of these two ideas:

The siblings play a board game to pass the time.

OR

The power to the basement goes out, scaring everyone.

The story could end with the power to the house coming back on and the kids are happy that they don't have to stay in the basement any longer, or the storm would stop (but the power is still out), and the kids walk outside to get some fresh air.
