Dear Home Ec 101,
The last couple times I’ve made drop biscuits they’ve been flat as a pancake. I have not altered the recipe. Can you tell me why?

I am willing to bet the culprit is your baking powder. This pantry staple has a relatively short shelf life and should only be purchased in small quantities, unless you are an avid baker. Once opened a tin of baking powder will only last three to four months in a cool dry place. If the weather is warm and muggy, its lifespan will be considerably shortened.
There is a simple method to test my theory. Simply add 1 tsp of baking powder to a half cup of hot water. If active, it will bubble in the water. If nothing happens, it’s time for a new tin.
