<span class="newwin">[https://www.echinobase.org/entry/literature/article.do?method=display&articleId=42133 '''Sea Urchin Fertilization Laboratory''']</span><br />
Vic Vacquier developed a handout for university students on how to observe sea urchin fertilization in a university lab class setting. All that is needed are sea urchin gametes, a microscope, a few solutions and this handout. The handout works well for both 1 or 2 three hour labs. The student reads through the handout, makes the simple observations, and does the simple, direct experiments to gain insight into the fascinating process of sperm-egg interaction and egg activation.


<span class="newwin">'''Ocean Life Class for K-5'''</span><br />

<p>Class objective is to instill a sense of wonder and curiosity at the diversity of invertebrate life and forms in the ocean.</p>
<p>The worksheets that follow are suggested to be used in a class involving live marine invertebrates purchased from marine animal suppliers.</p>
<p>The discussions and activities depend upon the facilities available and the area of study of the host aquarium and lab.</p> 


<span class="newwin">'''Ocean Life Introduction'''</span><br />

The oceans are rich with life, this sheet shows common marine invertebrates.
