Echinoderm dissection

Yesterday students read information about echinoderms and completed the pre lab questions. They then observed and labeled the external parts of a starfish.

Today students continue with the sea star dissection and find the digestive system, tube feet, ampules and ossicles just to name a few of the internal features.

Tomorrow students will finish with the dissection and answer all the questions on the lab sheet.
