About this worksheet

Five small pictures show how a fossil forms on this 3-page 3rd grade science sheet. Students number them from 1 to 5, from a fish sinking to the bottom of a lake to a scientist finding the fossil. Page 2 then asks them to complete five sentences with the words buried, layers, minerals, bones and discovered. The answers page gives the order of pictures A to E and the five missing words. It suits the Fossils topic as a first look at the process.
