Science Experiments Elementary

Question: What are some good ideas for a science experiement involving dogs?
I was thinking about hiding some dog food somewhere and trying to see if my dog can find it, but that’s to elementary.
I need to do a more complex hypothesis statement experiment, example: IF dogs have good sense of smell THEN they’d be able to find hidden things.
Any ideas on what i can do? thanks
Answer: At first seeing your question I thought that you were going to do something that would harm the dog I was about find out were you live and equip my hidden blade……..
You should try to put some sort of food that smells on top of something high and see if they notice it by smell………i dont know
