Our Philosophy

The secret to engaging your students is actually not so secret. It’s all around us--it’s the act of looking out at the world.

Too often as science teachers we start explaining the world without spending enough time showing it. We’re so eager to get to the awesome conclusion that we often begin our lesson with it, rather than starting with observations which will lead to the conclusion. It’s like telling the punchline of a joke without the setup.

There is an art to selecting the best observations for students. The perfect video clips, photos, and activites lead students to the conclusion and make it unforgettable. Try out the site, you'll see.

Our Story

You've used many different websites when planning your lessons, but this website is different. Why? Because it's the result of a unique collaboration: a dedicated science teacher joined with a friend who is an expert programmer to create the website that he always wanted as a science teacher.

My name is Doug. That's me pictured above. I spent the last six years teaching every branch of science to 4th through 8th graders. And every night before class I struggled to get all my lessons ready for the next day. The truth is, it's more than a full time job to engage and excite your students every day.

I always felt there must be some way for all of us science teachers to help each other; we're all doing such similar lesson prep. My friend Keith, who is a programmer, is helping create the website I always wanted: a one-stop shop where I can select any topic that I'm teaching and discover a collection of great video clips, photos, activity ideas, and a bank of thought-provoking questions for quizzes and exams. I don't want completed lessons, those never fit my needs. I want the best raw ingredients that science teachers before me have found.

As a science teacher, my job is to unlock the world around our students. I am a tour guide, helping my students to notice things they normally overlook. I take them to amazing places they’ve never been, and show them phenomena they never dreamed existing.

Whenever possible, I want to show my students real examples of what we’re talking about. If I can put a physical sample in their hands, do a live demonstration, or take them out in the world -- that is the best. But second to that, I want to show them striking photos and short videos so they can see for themselves. I want to recreate the process of discovery and lead my students to the conclusion. Diagrams and illustrations have their place too, but as tools to help my students make sense of what they’ve observed. They’re not a substitute for showing them the real thing.

The lesson pieces on this website first came from my own collection of favorites which I amassed over the past six years. But immediately I began talking with fellow teachers and getting their favorites as well. We're curating the best pieces from around the web and from teachers' personal collections.

Enjoy, and any place you can add to make this collection better, please do!

See you on the site,

Here's what other teachers have to say
This website has so many great pictures that illustrate science material. You don't have to look anywhere else. They've already picked out the best ones.
- Suzanne
This is an image repository specifically for science images that have been vetted to make sure they really demonstrate some science content. This will save time not having to weed through all the non-science images.
- Kristen
This is a site with images on, really, any topic in science. If you're searching for a specific image to reinforce what you're teaching, this is a good resource that covers all of the different topics you might hit in middle school. It helps to show students more images, different perspectives, and something with a wow-factor.
