Ever wondered what it actually looks like as samples are collected from the floor of Lake Michigan?  A science teacher from Elk Grove High School in Illinois got to the bottom of it for you.
When it came time to lower the multi-corer and hydraulic extruders, Quinn Loch strapped on a GoPro video camera to go for the 158-meter ride to the bottom.
 
Loch, along with 14 other educators, is working with 4 scientists as a part of the Shipboard Science Workshop aboard the U.S. EPA R/V Lake Guardian.
 
The cores will be used to study dissolved oxygen and phosphorous levels in the water just above the cores.
 
The educators and scientists stand on the dock in Manitowoc, Wis.
Be sure to follow the educators on twitter at #lakeguardian and on the Teacher Features page on the CGLL website
 

They will continue tweeting and blogging until the trip’s conclusion on July 18.

When participating in a crayfish participatory science activity, be sure to snap plenty of photos of any crayfish you catch or observe. Not only is it a great way to capture the fun and excitement of the day, but it also helps document the species present. To ensure accurate identification by scientists, it’s important to provide clear photos from multiple angles. Dorsal (top), lateral (side), and ventral (underside) views of the crayfish should always be photographed.To learn more about the specific features to highlight in your photos visit the link in bio or InvasiveCrayfish.org/Management/#Community
Who says “Back to School” means back indoors? While the weather is still warm, take your students on an outdoor science adventure by exploring crayfish in your local waterways.The Invasive Crayfish Collaborative invites grades 2-12 educators to take part in a hands-on participatory science activity. By catching, identifying, and reporting crayfish species in your area, students contribute valuable data that helps scientists better understand where native and invasive crayfish live.Check out what other educators have found and get involved: inaturalist.org/projects/great-lakes-crayfish
