I really like trees. They're pretty, and green, and provide shade from the hot sun. But my
friend Joe says we really NEED them. Is that true?
My grandfather always mutters that the world is getting too crowded.
Is that true?
My teacher says I'm part of a food web. That sounds scary. Am I really?
Am I going to get tangled up in it? What is it?
My family and I recently went to a house made to look just like it did over 200 years ago during
Revolutionary War times. How come the front door was so short, and the bed so small?
Could it be that people are taller now than they were back then?
I had x-rays taken. How can they see inside my body?
