Imagine that you are Karl's friend and he is asking your advice about what to do with the meteorite. Write Karl a letter or make him a video with your advice.
Dear Karl,
I'm so excited to hear that you've found a meteorite! It's a really special and unique discovery, and I'm sure you're wondering what to do with it.
My advice is to first research the meteorite and find out as much as you can about it. You can look up information about its composition, age, and origin. This will help you understand the meteorite better and make an informed decision about what to do with it.
Once you've done your research, you can decide if you want to keep the meteorite or donate it to a museum or research institution. If you decide to keep it, you can display it in your home or office, or you can even have it cut and polished to make a beautiful piece of jewelry.
No matter what you decide to do with the meteorite, I'm sure it will be a great addition to your collection.
Good luck!
Sincerely,
Your Friend
