Solar Eclipse 2017

We are excited to announce that on Monday, August 21, 2017, all Grayslake Central High School students and staff are invited to participate in a special GCHS Solar Eclipse Celebration.  In an effort to provide our students relevant, engaging and authentic learning experiences, we are choosing to alter the instructional day for this rare celestial event.

To help understand this event, here are some basic Q&As:

Q: What’s happening on August 21, 2017 – and why is it special?
A: A partial solar eclipse at 88% of totality. Only portions of the world are able to view any solar eclipse, so the opportunity for our students to view this size of an eclipse is a rare opportunity.


Q:  How are we going to safely view the eclipse?
A: Our primary goal is keeping our students and staff safe. Event participants will wear special, medically-approved solar eclipse glasses purchased from Flinn Scientific (AP9562) to protect their eyes, because they filter out 100% of harmful ultra-violet, 100% of harmful infrared, and 99.999% of intense visible light, and meet NASA approved guidelines (ISO 12312-2).  Additionally, students and staff will be trained on safe eclipse viewing practices.


Q: Who gets to participate?
A: Assuming weather is clear and calm on the eclipse day, all GCHS staff and students who have not opted out will participate directly in the viewing assembly. 


To request a student opt out and remain inside during the eclipse, please complete this form:, or leave a voicemail message including student name and grade identifying that a student will opt out for Deanna Mazanek, Science/CTE Department Chair, at 847-986-3300 x5503.  Students who opt out will watch the live stream of the eclipse event inside the building.
