As a science teacher, I’m a stickler for the use of a pencil because I dislike wading through cross-outs to find an answer, the smear of ink on my fingers, and the general lack of neatness involved with students and ink.
This presentation gives students a bit of the history and chemistry of the amazing pencil. From the reason we call it a pencil “lead” to what it means to be a #2, students will appreciate what was once the most remarkable educational technology!
Use it to create a positive atmosphere about using pencils in your classroom, as a presentation on the history of ordinary things, or to illustrate a point (LOL). It is appropriate for grades 5-12. I use it in pre-AP chemistry and physics and AP Physics. It is also an excellent addition to your math class if the use of ink is an irritation.
