Unit studies in High school -Geography

I am using MFW highschool curriculum but wanted to add in some Geography this year just starting with some countries that we didnt get to when we did MFW in 4th grade like China, Vietnam, Iran (especially with recent events) do you think that is do-able? I thought maybe do an extra week or so since if we go with our current schedule we will be getting done by May and might not have all the hours in. I would add this when my boys are getting burned out by what they are doing now as a “break without a break”. I would do animals found in the country, the people, the environment, for language maybe a paper at the end of the week on something they learned. Does this seem like something you would find in high school (its been a while since i have been in high school) I also thought that they could find a recipe that is from those countries and we would make a meal. I would love opinions…
