4. Shark tagging. My friend David Shiffman needs volunteers to help him with his research for school. Do you like Shark Week? Then, you're going to love being a citizen science with David. He tags (small) sharks for his research in sharking feeding behavior and ecology; and his research also helps to measure the size and health of the shark populations in the Coastal South Caroline sea. Over 30 different species of sharks call that coast home. It's very interesting work and definitely will give you something to talk about at parties forever. You can learn more about his research here and follow his blog about sharks, marine biology and conversation of the ocean and its creatures at Southern Fried Science and on Twitter @WhySharksMatter.
