Junior Ranger Booklet

You can complete the entire Junior Ranger Booklet and earn your certificate below or select two activities from the book along with one of the other activities below to earn your Junior Ranger Certificate.

Earn a Super Junior Ranger Certificate

Learning new things was very important to Thomas Edison. Here is a way to learn something about another National Park. If you participate in the Junior Ranger program at Patterson Great Falls National Park, Morristown National Historical Park, and Thomas Edison National Historical Park you will be presented with a Super Junior Ranger Certificate.
What park did you visit first? What is something you learned at each park?


While taking a virtual tour of Thomas Edison’s Laboratory, see how many items you can spy. Start by looking for 6 items on each floor to complete the activity. Keep trying and see if you can find all the item. Click here for the tour and items to find. Good Luck!

Design Your Own Invention

Thomas Edison kept his ideas, notes and drawings in laboratory notebooks. Today the park has over 3000 of his and his worker's notebooks. When an idea came to Edison, he would sketch it out in one of the his notebooks. Sometimes he would continue and research the idea, other times he would put it aside for later. What ideas or inventions have you thought about? Now is your chance to capture those ideas. You can save it for a later date or begin to research your idea and see if you can create a prototype. You can draw your idea on a blank sheet of paper or use the form here. Don't forget to name your invention and date it.
