The Lesson Pony

I have developed lessons designed primarily for middle and high school students in science. These labs have been classroom tested for many years. Awards 2007-2005 Professional Learning Grant from the Waltham Chamber of Commerce 2001, and my name is on Mars 2001 Mars Rover for my contributions to NASA educational system.

Chemistry Invisible Ink Lab History

(0)
Teach physical and chemical change thru the science of “steganography” in this easy-to-implement yet highly engaging lab. No chemistry experience is required. However, this lab is a great addition to working with your history department to make the Revolutionary War come alive. George Washington used this technique to send coded messages throughout the war. Students will discover that the juice of lemons contains carbon which will enable them to write a secret message in the same manner as the Continental Army did in the 1770s. MATERIALS ½ Lemon Saucer Water Teaspoon Cotton swab White paper Lamp (any heat source)
