Amazing Annelids

Annelids? Okay, we're talking about ordinary earthworms...but annelids are their scientific name. The fifth graders are working on an animal unit in science class and we have started with the invertebrates.

On this day the students spent some time observing their worms and then they designed an inquiry science experiment to explore worm behavior. Here are some of their experiments:

This group designed a maze and timed the worms as they crawled through it. They sprayed one worm with water and kept one dry to see which would be faster.

In this experiment the students are discovering if worms like cold or warm temperatures. The lab tray contained a pile of snow and a warm paper towel.

This student designed a black cylinder to see if the worm preferred dark or light areas.

Can a worm untie itself from a knot? This student found out!
