Looking for a fun, hands-on way to engage your students this year? Check out our new curriculum about crayfish and freshwater ecosystems! This curriculum teaches students about the importance of native crayfish, the threats posted by invasive species, and the health of Great Lakes ecosystems. It includes 9 ready-to-use lesson plans, with one featuring our participatory science activity! All lessons are aligned with NGSS, CCSS, and CGLL Principles.
Download the curriculum and start exploring at InvasiveCrayfish.org/Crayfish-Curriculum

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

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.

Come round up some rusty crayfish and help remove this #invasivespecies from the Fox River at the 7th Annual Rusty Rodeo. Join us at this FREE event and help collect, identify, and remove rusty crayfish from the river using aquatic nets and buckets. Prizes are given to the participant who collects the most, the largest, and the smallest rusty crayfish. Learn more about native and invasive aquatic species at educational pop-
up exhibits.
Participants will need to provide their own supplies. We suggest bringing an aquatic net, a bucket, and clothes and shoes you don’t mind getting dirty. This is a partnership program with: Forest Preserve District of Kane County, St. Charles Parks & Recreation Department, Fox Valley Park District, and Friends of the Fox River. No registration required.
