🧪 Science with Sarah: A pinhole projector for a solar eclipse🌞

👉 Watch the video of Sarah’s science experiment at Bonnie Ellison Elementary here!

Hello parents, teachers and students! Need a fun and safe way to view a solar eclipse? Try making perforated displays for these cereal boxes. It’s sure to dazzle you and your kids, even if you don’t have solar eclipse glasses. Even if you do, this is an engaging way to get our young students interested in eclipses!

Remember: It is never safe to look directly into the sun… even with sunglasses. Therefore, during a solar eclipse, you need to use proper eye protection.

Be sure to check out GMSA@9 on Wednesdays when meteorologist Sarah Spivey demos and explains the science behind it.

  • Step 4: Place aluminum foil over one slot.

  • Step 5: Using a printing pin, make a small hole in the aluminum foil.

  • Step 6: Use the pinhole projector to go outside and place your back facing the sun. Look through the open side of the top and move the box until the sun is focused in the hole and you can see the sun’s reflection on the white paper at the bottom of the box. If it’s cloudy or you’re under a tree, you’ll see these too!

How it works

The hole focuses strong sunlight into the grain bin. A perfect projection is made on the white paper in the background!
