End the Week With a Bang

Cultural Considerations

None- these demos cross cultural barriers and excite any students. It is particularly useful for lower-track or learning-disabled students, who may otherwise have a hard time relating to chemistry.

Actions

Many of these demos are easily found online and on youtube and, with tinkering, can be adapted to your classroom setting. For example, the alcohol rocket is just an empty water bottle sprayed inside with rubbing alcohol and attached to a string by a straw. Make sure there is safe distance between you and the students and provide safety gear to the closest students. Smoke-producing reactions should be performed in a fume-hood if possible.

Resources

Safety gear- goggles and gloves; lab-coat for teacher
Common chemicals- rubbing alcohol, hydrogen peroxide, potassium permanganate (a water purifying agent), sulfuric acid (CAUTION!- can be found in auto shops for car batteries)
For rocket- water bottle, nozzle (from squirt tops or a hole in the cap), straw, string
Beakers, long-necked lighter, dropper or pipette

Description

End the Week with a Bang is the idea to have an exciting, explosive, demonstration at the end of chemistry class once a week that is relevant to the material being learned. I was motivated to start this when I realized that students were finding abstract ideas such as calculations and chemical equations boring, not realizing the exciting reality they are based on. I do these demos either in the lab or in the classroom using various fiery reactions found online or in chemistry demo textbooks.

For us, the highlight of the week was when Mr Goldberg would End the Week with a Bang. He truly loves science, and I honestly miss his class.

As a former student of Mr. Goldberg, I can testify that not only did these experiments have relevance to exactly what we had been learning about each week, but they kept the class engaged. Science (chemistry especially) is a hard concept to directly identify with and demonstrating the science and how we can apply it is a very difficult thing to pull off as well as Mr. Goldberg has and continues to do. Vote Mr. Goldberg!

I wish that Chayim Goldberg was my science teacher. Awesome experiments, state of art teaching techniques
