NEED help with a mnemonic

Hi guys, I am in my third semester of nursing school and currently putting together my very first community teaching project, which I will be doing for an elementary school. I am super excited! However, I am stuck, I have all these creative demonstrations and visuals for my teaching one of which includes a poster using a mnemonic with the word GERM, since my topic is preventing the spread of germs. My problem is I used a thesaurus and came up with a bunch of relevant words for each letter, however the ONLY mnemonic I could come up with using these words seems like it might not be age appropriate for the younger kiddos in the school. My mnemonic is:

G=germs

E=enter our bodies,

R=reproduce and

M=make us

S=sick

I was hoping you awesome allnurses ladies could help me create a more age appropriate mnemonic using this words, to help kids remember what they do or how to prevent them, ect. FYI....I give credit where it is due, and will give credit in my report, as to where/how I came up with the mnemonic, as I did for all of my research for this presentation.
