Question

Julie finds a snail on the sidewalk and wants to know whether or not the snail moves throughout the day. She places a single mark on the sidewalk next to the snail.
What will Julie use the mark for initially?

Answer 1

To make a base line mark to know where she started measuring the snails movement, at the end of the day she can measure from her first line to her last to see how far the snail went.
Hope this helped!
