I think my bio teacher, who is also a young mom, is a good teacher. She compares her son and daughter and their ever-coveted goldfish to competitve interactions of interspecific competition. She brings in their pairs of different colored mittens when trying to illustrate mitosis.
The other day she was explaining how both species can benefit in an interaction:
"My son wants to stay up later. So I say, okay, you can have 30 extra minutes, if you play with my hair." Mutualism.
I hope I'm that kind of mom.
