The Digital Declaration of Independence

The Digital Declaration of Independence is a cool use of the Neatline mapping and timeline tool. The Digital Declaration of Independence is an interactive display of John Trumbull's painting Declaration of Independence, scan of the text of the Declaration of Independence, and a map of the hometowns of the signers of the Declaration of Independence.

When viewing the Digital Declaration of Independence you will see that each person's head has been highlighted. Click on a highlighted head to be taken to that person's name, to see that person's hometown on the map, and to view a short biography of the person.

Applications for Education
The Digital Declaration of Independence could be a good reference for students to learn about some of the men who signed the Declaration of Independence. Aside from that, the Digital Declaration of Independence is a great model of what can be done with the Neatline mapping and timeline tool.

Measure the Speed of Light With a Chocolate Bar and Microwave

A few years ago I wrote about Jefferson Lab's YouTube channel that includes a playlist titled Frostbite Theater.  Since the last time that I watched Frostbite Theater the playlist has expanded to 68 videos. The videos offer short lessons on chemistry and physics topics.

One of the Jefferson Lab videos that I watched this evening is titled Measure the Speed of Light - With Chocolate! The three minute video is a demonstration of an experiment in which students use a chocolate bar and a microwave to attempt to measure the speed of light. As Jefferson Lab pointed out in the comments, the experiment could also be used to attempt to confirm the microwave's frequency. The video is embedded below.
