The "Chemistry Quint-a-sense" series is a fun way to involve all five senses in the learning process.
Students are given an audio-visual treat that is followed by a second treat that can be touched, tasted, and smelled!
WHAT WILL I GET WITH THIS PRODUCT?
This download, week 27 in the Chemistry Quint-a-sense series: Ethylene, is one of my favorites... it involves a classic combustion demonstration of ethylene in ripened orange skins. After the lesson and demo at the end I allow my students to come up to the candle with their own peels. This installment talks about the connection of ethylene to the manufacturing of multiple synthetics. It is meant to correlate best with the third week in March, around March Madness.
You will get a sharable mini-lesson, which can be presented over the course of 5-15 minutes, and remembered for years, depending upon your audience. The download comes with three sharing formats: Smart notebook, PowerPoint, and PDF.
Note: You will need to obtain the sharable ripe oranges separately. Be sure they have thick ripe skins, and try not to excessively bend/bruise the skin while removing it from the orange so that you don't release the ethylene until you are ready! The best effect is achieved if you pre-cut an orange into 8 slices, eat the pulp, and twist the peel with a quick action directed at a candle flame. While the demo is mostly harmless, producing a brief sparkling flash, I must remind you: run it yourself first, and as always you are responsible for the safety within your own classroom ;)
IDEAS FOR USE:
Although the mini-lessons in this series occasionally tie in with the calendar and build progressively upon each other, each mini-lesson is also self standing and can be used completely independently.
Suggested ideas for use:
1) In the original "once per week" chronological order.
2) As a fun "change of pace", whenever needed.
3) As a "hook" for the start of a chapter, Unit, or lesson.
4) As a "reward" for participation, attendance, or test average
5) In a "continuous series" to start each day or lesson in a particular unit of study or month.
