My son has a science project due this month on magnetic suction . The
experiment will show how a door bell rings. His teacher would like him to
extent this project by finding other examples for display to compare to his
project(how a doorbell rings) I am not sure what what to do. I need your
help. Science projects always made me stressed, I don'twant My son to feel
the same way.
Thank
you for your help,
Nancy DeRoo
