SOLAR Eclipse 2021

The Annular Solar Eclipse on June 10, 2021 is a once in a lifetime opportunity to view an incredible astronomical event, and will be best seen in the path of annularity in Northern Ontario, Northern Quebec, and Nunavut.
Discover the Universe is excited to help schools learn about eclipses and observe the June 10 eclipse safely. We are offering free Eclipse Kits to teachers, with a priority given to schools located in the Path of Annularity (see map above).  
Thank you for the unbelievable response!
We are no longer accepting orders.

Note that our Eclipse Kits are only for schools and classrooms.

If you are looking to order glasses for you and your family only, please use the order form through The Dunlap Institute.

About the Eclipse

Why is this eclipse special?

Solar eclipses visible from any location don’t happen often! The next total solar eclipse visible in Canada will be in 2024, and the next total or annular solar eclipse visible in Nunavut, Northern Quebec, or Northern Ontario will happen in 2048 at the earliest. This particular eclipse is an annular eclipse, which means that at its maximum, you will see a ring, or annulus, of the Sun around the Moon. Given this once in a lifetime opportunity, take advantage of our kits to teach your students about eclipses and ensure that they have the equipment necessary to view the eclipse safely. Note that everything in the kit can be kept and reused for the next partial, total, or annular eclipse that happens for your region. Some resources can also be used to teach about lunar eclipses, which are more frequent.

What is an annular solar eclipse?

A solar eclipse happens when the Moon passes between the Earth and the Sun, casting a shadow on the Earth. From our perspective, this will look like the Moon is blocking out the Sun. This particular eclipse will be an annular eclipse. This occurs when the Moon is further away from Earth and does not block out the Sun entirely - creating a ring, or annulus, during the eclipse. The annular eclipse on June 10 2021 is a once in a lifetime opportunity to view an incredible astronomical event, and due to the specific locations where it will be visible, has been nicknamed the Arctic Ring of Fire.

What is the difference between an annular eclipse and a total eclipse?

During a total eclipse, the Moon can cover the Sun completely and it gets much darker for a few minutes. This isn't the case for the June 10 eclipse. The Moon will appear slightly smaller in the sky because it will be further away from Earth. It won't cover the Sun completely and a ring of Sun will still be visible. It is important to always use the eclipse glasses to observe the eclipse. Even during the maximum eclipse on June 10, about 12% of the Sun will still be visible and that would be enough to damage your eyesight.

What will happen on June 10, 2021?

Early in the morning of June 10, the Moon will pass in front of the Sun, creating a solar eclipse. Depending on where you live, the eclipse will start before or after sunrise (see map) and will therefore be visible very early in the morning. The eclipse will need to be observed before school. Everyone located in the path of annularity will get to see the best show: a ring of Sun in the sky! People in the path of annularity will see the ring of Sun around the Moon for a few minutes at the time of maximum eclipse. The partial eclipse periods will last for about an hour before and after the maximum. People outside the path of annularity will see a partial solar eclipse, where the Moon will cover part of the Sun, but not enough to create a ring. More detail about exact viewing times for different locations will be provided very soon on this webpage. You can also visit the website for more information about your specific location (once on the page, click on the map for time details):

Why is it dangerous to observe a solar eclipse without eye protection?

It is always dangerous to observe the Sun, but we naturally tend not to look at it on any sunny day. During an eclipse however, we want to look at the Sun and we need to do it safely. The easiest way to do it is to have ISO certified eclipse glasses. Looking at the Sun without proper eye protection, including during an eclipse, can severly hurt your eyesight and even damage it permanently. Each of our Eclipse Kit comes with 50 eclipse glasses, which allow you and your students to view the eclipse easily and safely. The only requirement to use the eclipse glasses is to hold them in front of your eyes while looking at the Sun and the eclipse. There are other ways to safely observe solar eclipses and we will be providing more information on this webpage in the coming weeks. Come back for more information!

About the Kits

Why do you need a kit to get the most out of observing the eclipse?

We built the kit to make it easy for you and your students to learn about eclipses and to observe it safely. Since it is dangerous to look directly at the Sun, even during an eclipse, we are providing ISO certified eclipse glasses for your entire classroom. Observing with these glasses is very simple and safe: the only requirement is to hold them in front of your eyes while looking at the Sun and the eclipse. We're also providing the best educational material we know of to talk about the eclipse to your students. We think this is a unique opportunity for your students and your community and we want to make it easy for you to enjoy the show safely! Make sure to order your FREE kit soon, and tell your colleagues about it. While eclipse glasses are the easiest way to observe the eclipse safely, you could also enjoy the eclipse without one of our kits. We will be providing information and tips on this webpage as we get closer to the eclipse date. Come back for more information!

What is the purpose of the kit?

The purpose of this kit is two-fold. From a safety and accessibility view, we want to ensure that everyone in the path of annularity will have the safety and information tools they need to observe the eclipse. ISO certified eclipse glasses are one of the easiest ways to observe the Sun and the eclipse easily and safely for students of all ages. From an education standpoint, we want to ensure that every teacher has the educational tools they need to teach their students about this incredible celestial event and enable their students to observe the event meaningfully.

What comes in the kit, and why are these items included?

A standard kit comes with: • 50 eclipse glasses; • 1 eclipse demo activity; • 1 USB key with educational material; and • 50 information sheets; The eclipse glasses are included to ensure that everyone is able to observe the eclipse safely and make the most out of the experience. These are to be distributed to your students so they can observe the eclipse at home since the eclipse will happen early in the morning, before school. These eclipse glasses are ISO certified and are safe for direct solar viewing. Our glasses look like rectangles with a dark filter in the middle, as shown below. To use the glasses, hold them in front of your eyes as you look at the Sun and the eclipse. The eclipse demo activity is, in our opinion, the best way to demonstrate eclipses in the classroom. More information here: The USB key and educational materials are intended to remove the pressure on teachers to create their own lesson plans and content on this topic and provide ready-made, curriculum-connected material. The information sheets are intended for students to share with their families so that the community is included in this remarkable event and everyone can observe the eclipse safely. The information sheet is available in English, French, Inuktitut (Nunavut), Inuktitut (Nunavik), Swampy Cree, James Bay Cree, Oji-Cree and Ojibway.

How do you order a kit?

Kits are completely free of charge, so all you need to do is tell us what to send and where! We will require a complete address (including postal code), the name of the contact person who will receive the kit, an email address to follow-up with your order, and if you would like a standard size kit (recommended for 1 classroom) or to customize your kit (if you're ordering for multiple classes). We recommend ordering a standard size kit per participating classroom, and encourage teachers to distribute any extra glasses to other staff and to students with siblings at home. If you are ordering on behalf of a school, please feel free to order extra glasses and info sheets along with your kits. SAMPLE ORDER: An order for a school should consider how many teachers will use the eclipse demos and educational material and the total number of students in the school. For example, if there are 3 science teachers in a school and 500 students, we would suggest ordering 3 standard size kits and an additional 350 eclipse glasses and info sheets.

What is the timeline for receiving a kit? When should you order?

These kits are designed with teachers and students in mind, and would be best used before the eclipse to help your students understand the phenomena they are observing. We would recommend incorporating lessons from the kit at least 1 week before the eclipse, but the earlier the better! At the latest, you should plan to receive your kit 1 week before the eclipse, preferably in late May 2021. Considering packing and shipping timelines, we recommend schools in Nunavut, Northern Quebec, and Northern Ontario to order by APRIL 10 2021.

These kits are specially designed to support teachers in educating students on eclipses! They contain everything you need to teach a module in advance of the Annular Eclipse on June 10, 2021. They include a demo you can build with your students, as well as resources and activities for in-class use on a USB stick. 
Don't miss your chance to get all the tools you need to educate your students on eclipse safety!
You should NEVER look directly at the sun!
However, we are including eclipse glasses that will protect your eyes from the damage direct sun rays can cause. Make sure you are safe when observing this Solar Eclipse, order your free kit today!
