We used a fish bowl template out of an old Mailbox magazine, but you could always draw the bowl. Step 1 was to make an orange hand print in the bowl with your thumb pointing down.
Next, we added a googly eye and drew a mouth. Most of my kiddos made a big smile on their fish!
To finish students had to cut out labels and attach them to the proper fish parts.
I adapted this lesson off of a pin on Pinterest. There are many versions out there, but this is the one that fit the science standards and goals we were working on.
