🦇Yesterday, OPG enjoyed hosting the Bat Ecology and Research Workshop with Dr. Brian Hickey and the St. Lawrence River Institute education team at the Saunders Hydro Dam Visitor Centre. A huge thank you to Brian and his team from the River Institute for organizing the event and making it so memorable!

🦇🌙Guests had the opportunity to engage with Brian throughout an educational presentation about bats, participate in various crafts for kids, a family-friendly scavenger hunt, and even observe four real bats that were caught, studied, tagged, released and tracked!

🦇🌙The event welcomed 45 people with an interest in learning about these nighttime creatures.

🦇A big thank you to everyone who joined us at the visitor centre last night. Your participation and enthusiasm were much appreciated! We hope to see you at our future events.

🧪Get ready to dive into the fascinating world of all things icky and discover the science behind the things that make you say “eww!”🧪

Join us and Scientists in School at the Saunders Hydro Dam Visitor Centre on Monday, July 20 (10:00am - 11:00am) for a hands-on science workshop where kids will explore viscosity by creating their own “snot,” identify different animals by examining their s**t (yes, p**p!), and discover the wonders of digestion by producing a burp in a bag.

✅Admission is FREE, but registration is required.

Recommended for ages 4–12. Families are encouraged to participate together, and one activity kit will be provided per family.

🎢⚙️ What an incredible afternoon of science, creativity, and hands-on learning!

On July 9, the Saunders Hydro Dam Visitors Centre partnered with Scientists in School to host our Ride ‘n’ Roll with Science workshop, welcoming 39 participants for an exciting STEM adventure.

Participants explored the science behind amusement park rides by building spinning rides to investigate gravity, creating bumper car arenas to learn about forces and collisions, designing ziplines to discover potential energy, and constructing roller coasters while experimenting with motion, speed, and energy.

Thank you to everyone who joined us for this fun-filled afternoon, and a special thank you to our partners at Scientists in School for delivering such an engaging and interactive workshop. We hope to see you at another event soon! 💙🔬

🐠On Friday, July 3, OPG had the wonderful opportunity to be part of the annual Family Fishing Event, hosted by the Raisin Region Conservation Authority.

🛟OPG hosted a booth where families stopped by to learn about water safety around dams, discover how hydroelectricity works, and take home a variety of fun giveaways.

🎣The event was a great success, with families enjoying a day of fishing while exploring the different booths of our amazing community partners. To end the day, prizes were given to five winners for different fishing category awards.

☀️With beautiful, sunny weather and plenty of smiles, it was a fun day that everyone enjoyed!
